Buick - Century :: A/C Not Working Properly - Compressor Malfunction


Jun 23, 2015

I recently put in a new compressor and accumulator. I didn't change the orifice tube since it is almost impossible to get to. I added freon and oil with dye and it would work fine sporadically sometimes it wouldn't get cold at all other times it would be freezing. This lasted about a week. I noticed that when it was hot the clutch was engaging fully but I felt the pipe near the firewall and it wasn't cold as if the compressor wasn't compressing and then it would start compressing and it would get cold. The compressor sounds different when it was making the car cold. This led me to rule out a problem in the air control doors. Now there seems to be a leak which is bad since it runs out almost immediately. The problem is finding it since there isn't any oil residue or freon dye where I can see.

(Looking for some shortcuts where I don't have to remove the vacuum brake, brake booster to change the orifice tube?)

Buick - Century :: 2000 - Windshield Wipers Won't Working Properly

I have a 2000 Buick Century. The wiper controls are all goofy. The delay seldom ever works, just goes into slow steady speed most of the time. And they go through several more cycles when wipers are shut off. No doubt some entire multifunction module will have to be replaced.

Buick - Lesabre :: ABS Malfunction - Brake Pedal Not Functioning Properly

My brake pedal needs to be practically be pushed to the floor for the car to stop. I went to a Munro Muffler and they replaced all brake pads and turned the rotors. The problem of the pedal to the floor did not go away. The Munro tech struggled with this then popped me with this estimate - brake lines master cylinder to ABS / brake lines ABS to front brake flex hoses connections, / brake lines - ABS to rear junctions fittings at the passenger front door. Also they want to sell me a rear wheel bearing because the temperature at one point was very high. The total estimate is $840. I can remove the Rear wheel bearing to bring the estimate down to 500. I asked if we could do lines from ABS to Master Cylinder only and the tech advised against it. I feel like I am about to get ripped off and am going for a second opinion.

Buick - Century :: 2001 - Digital Odometer Not Working

I drive a 2001 Buick Century. Sometime last month (or maybe the month before), my digital odometer was on the fritz. There's a little sub-partition to my dash that houses my digital odometer as well as the indication as to what gear i'm in (PRND32). So it started fading a little, then on some days it wouldn't light up at all. I know the odometer is still working, because on the days when it would light up, it didn't pick up where it left off, rather it had been working the whole time I couldn't see it. And this started going in and out more and more frequently until now it hasn't lit up in about a month.

So, i take my car into my mechanic for an oil change (just had to guess at how close i was to 3,000 miles) and I ask him about it. He tells me that it'd cost so much in time and parts that I might as well not even fix it.

So now what? I'm fine just driving around without it. I know what gear I'm in without my car having to tell me, and I guess I can just estimate when to get my oil changed, although it's rather inconvenient. But what do I do when I want to sell it or trade it in? The longer I go without knowing my mileage, the farther afield an estimate will be.

You know, what I was thinking is that I really just need someone to run a red light and total my car. Then insurance would cover me and the odometer would be low on my list of worries. I just hope the airbags still work...

Buick - Century :: 2001 - Fan Stopped Working On The First (low) Setting

I have a 2001 Buick Century which is more or less reliable. Last year the fan stopped working on the first (low) setting, but continued to work on levels 2-5. Air came out of all of the vents, using the fan, A/C, or heat with no problems. A few days ago, level 2 stopped. The next day levels 3 and 4 stopped. The fan still works on the highest setting, but it's just starting to be summer in Minnesota and I'm worried that level 5 will stop on the hottest day of the year. Is this a simple fuse problem I can fix myself? Complicated repairs are probably beyond me, but I can do basic repairs.

Buick - Century :: 1996 - Brake System Won't Working?

I have a 1996 Buick Century that I started having problems with tonight.

As I was driving, I pressed the brake pedal down and it felt like I lost most if not all of the pressure in the brake system and it was a bit difficult to come to a complete stop for the rest of the trip.

I admit that the system hasn't been maintained in quite some time, but I recently filled up the brake fluid reservoir (2-3 weeks ago) after the brake dashboard light came on and the brakes worked just fine after this.

What is wrong with my car, and how do I fix it as cheaply as possible (or is it a cheap fix?)?

Santa Fe (CM - 2007-12) :: 2009 A/C Malfunction Blowing Hot Air Randomly - Control Not Working Properly?

My wife drives a 2009 Hyundai Santa Fe Limited which we bought new back in 09. she has put roughly 140,000 miles in that time span. We have religiously followed all required maintenance routines; this is the first major issue we have EVER had with our Santa Fe. The issue we are having involves the AC unit. Instead of blowing ice cold air, the air vents are blowing hot air as if the heater is on. I have check all major AC components and everything is working properly. I believe we are having a controls issue.

At one point, all vents would only blow hot air. The other day, the passenger side vents started blowing ice cold air while the driver side still blew hot air. The driver's side has not blown cold air since this issue started about a week ago. We do have dual climate control; I have tried every possible combination of controls to see if it's a particular switch or button; however, I have not had much luck.

Century :: 2000 Buick Cannot Get To Start

I have a 2000 Buick Century that I cannot get to start. While my wife was driving home it started to sputter (like running out of gas) and did a little back firing. She made it home and I put in some gas (Just to make sure) and the care cranks over but will not start. I have replaced the fuel filter, checked the spark plugs and replaced the CAM Sensor. The car still will not start.

Buick - Century :: 2000 - Oil Getting Into Coolant

My wife has a 2000 Buick Century with about 150,000 miles on it. It has been relatively trouble free. Recently, the "low coolant" light began to come on.She took the car into a garage where she was told there was oil in the coolant and the sensor had been compromised. The cooling system was flushed and cleaned and a new sensor installed. The "low coolant" light continued to come on. She took the car back in. She was told the wrong sensor had been installed. When she went back for the car the second time, she was told the oil in the coolant was preventing the new sensor from working and there was nothing more the garage could do. I went in and asked questions, primarily how serious was the condition, and couldn't get a straight answer.

We are due to drive to Florida in November. My wife would like to take it to a garage there. Is it save to drive it as is? What are the implications of oil mixing with coolant? What is causing it to happen?

Century :: 1994 Buick 3.1L Running Hot / Not Overheating

I am having a very tricky problem with my Buick.

For approximately the last 4 months, it has been (at least according to the heat gauge on the dash) running pretty hot. Not overheating, but getting close. And it doesn't take long for it to get there. This all seems to have begun right around the time that my father and I flushed the coolant system.

Since then, I have replaced some parts, and learned a few things in the process.

I learned that there are bleeder screws which can be opened to let air bubbles out. And I have heard that the 3.1L is especially susceptible to them.

New parts which I have installed:

- thermostat
- coolant temperature sensor
- radiator cap
- upper radiator hose
- lower radiator hose

I have checked the water pump and it seems to be perfectly fine. No leaks. No signs of bad bearings. And it circulates coolant just fine. I have not been witness to either cooling fan, primary or auxiliary, switching on in a while.

The exact symptoms are these:

The heat gauge does not take long to get to mid-way point, but will sit at that point for a bit if the vehicle remains stationary. Once the vehicle is in significant motion, the heat gauge will climb fairly quickly, especially with moderately high RPMs. It WON'T touch the red though, but will get very very close to it. The car runs fine. It does seem to be a bit underpowered, but I am comparing it to my fiance's 1996 Olds Cutlass Ciera, which I believe has a different transmission. My Buick does not seem to have lost power since this problem arose. The cooling fans no longer kick on. The oil appears fine. The coolant as well. With the radiator cap off, coolant does not bubble out or shoot out.

I made sure after changing upper and lower hoses to fill the radiator, let the car run long enough for the thermostat to open, and then slowly poured more coolant into the radiator until it was full again. And the reservoir is at proper level and the the reservoir hose s not clogged.

I am not SURE, but I don't believe the radiator is clogged. I believe that covers it, at least as well as I can.

BTW, I do not know where the fan relays are, otherwise I would test the fans to see if they still work.

What the heck is up with my Buick? Also, it has 97,xxx miles on it, and the transmission fluid is at proper level and looks normal.

Pump :: 2002 Buick Century Will Sometimes Not Start

2002 Buick century will sometimes not start. Seems to correlate with warmer weather and happens after long drives. I try to restart within 10 minutes of turning off and it will start and then in a few seconds the car shakes and the engine dies. I can restart multiple times, but it will always die in a couple of seconds. If I wait an hour and retry, no problem. Once someone banged on the gas tank and that solved it. Mechanic cannot diagnose problem unless it dies while he is there. Should I replace the fuel pump or could it be something else?

Buick - Century :: 1995 - Idle Getting Rougher

My grandpa's old wood paneled station wagon is sick. The idle seems to be getting rougher and rougher with every time I kill the battery (I've somehow left my headlights on four times in the past two months and needed a jump). It's to a point now where if I don't throw it in neutral at stop lights and keep a tiny bit of gas on the engine it stalls out.

Notes:*When it first gets jumped after being dead, if I stop even for a second, it dies instantly.*While cruising - it is fine. *It idles smoother stopped in neutral than it does stopped and in drive. *It seems a bit rougher with the engine is cold, but still rough and can stall with the engine hot. *Some random times it idles just fine (like for example the first few seconds on start up, and then it sounds like the engine is decreasing in rpm automatically, and then it is rough again).

Could the dying battery and rough idle be related?? The battery guy says "if it starts fine, the battery is fine" (it does start fine, although keeping the radio on for 20 minutes without it running will kill it).

Also other problems with my car in case this has anything to do with it: *I have a leaky tail pipe*my ABS has recently been randomly engaging at low speeds (next problem to work on...)

Buick - Century :: 2001 - Sounds Like A Jet Engine

I have a 2001 Buick Century that started making a noise from what seems to be the engine. It sounds like a jet engine when I accelerate. The noise is still there when I cruise, but it evens out. It is loudest when going between 40 and 50mph. The car is not overheating, and other then the noise it drives fine. My husband at first thought it sounded like the catalytic converter had been stolen, but he rarely knows what he is talking about. What could it be?

Buick - Century :: 2002 Turns Over And Over But Does Not Start

Most of the time it has no problem what-so-ever, but once in a while it just doesn't start. It will turn over and over but that's it. Most of the time if I just let it sit for a few minutes (5-20) it will start right up no problem, but I've noticed when it does it often revs up as if I had my foot on the gas. (that took me a while to realize since I often touch the gas anyway.) Once it's running it runs great. The idle settles down to normal after a few seconds and the car runs as if there was no issue. It does this randomly.

I can drive it for days or hours with no problem, and then suddenly it just decides to leave me stranded. Usually i wait and it gets me home, but a couple times it didn't. I've drained the battery twice on two different occasions months apart trying it, and waiting and trying it. Both times with barely enough juice the following day to turn it over, it fired right up, rev'd the engine, then ran fine. I don't think it's an issue with fuel because on one occasion while trying to start it I laid into the peddle until I could smell gas under the hood- and it never has issue while running, only on start-up.

So far the only thing I've done is replace the spark plugs- it runs better now, but doesn't start any differently.

Buick - Century :: 1996 - Car Just Quits Without Any Warning

Driving this 1996 Buick Century limited,4 cylinder car normally, the car will just stop running without any warning, nor rhyme nor reason. Most of the time this has occured, a tow truck has been called, but prior to towing, the car started normally and ran without problems for quite a while. The car has been in the chevrolet garage multiple times, at least over nine, for this problem, but will never show up for the mechanic. There is no specific driving pattern to cause this to occur: it dies in normal driving on the street, starting from a stop, in parking lots,

Buick - Century :: 2001 - No Air Coming Out Of Vents

There's been an interesting progression of trouble with my 2001 Buick Century:

My heat/AC had been working fine for years. About a year ago, the dial which controls the force of air (off, low, high, max, etc.) broke. But the 'off' and 'max' portions still worked. I could get full blast, or nothing. I didn't do anything, because I could still get what I wanted.

Just yesterday, I switched my heat to max - and nothing! No air comes out at all now. Obviously this is problematic for the upcoming winter.
