Santa FE SM (2001-06) :: No Cooling From AC / Compressor Not Running
May 22, 2013
03 Santa Fe, 2.7 L engine. No cooling happening. Compressor not running. Jumpered both sides of the triple pressure switch. Jumpering Low/high side resulted in slight increase in engine rpm, Jumpering medium side and something turned on (didn't get a chance to investigate) but still no clutch operation on compressor. Wondering what to try next other than disconnecting and dropping compressor ?? Checked AC relay on the bench and the coil operates and contacts close, so that's good. Also10A fuse before relay contacts is OK.

99 lumina. Ac was not working. I added a few oz's and the compressor clicked on but cooling fans were not running. After 10 min of idling the fans did come on but went off after 1-2 minutes. It seemed like they were responding to coolant temp more than ac pressure. Do the fans run when the hi pressure rises to a certain point where the computer will turn on fans?

Have an issue with my front air con not working.....
When you start the car there is a rattle/squeaking noise, this sounds like a worn pulley, when you press the air con button to turn it on the noise stops. It does not make any sound changes to the unit/engine to indicate the compressor engages and the is no cooling from the unit.....
Is it a new compressor or is there a common fix for this issue?

I've decided the first issue w/ my new-to-me jetta I want to focus on is the cooling fan constantly running. I suspect this is potentially related to the temp gauge not reading anything, which I suspect might be because of the coolant temp sensor.
So basically, when I turn the key to on (I'm pretty sure it's on, not start), one of the cooling can comes on. It's the fan on the right side as if you are sitting in the driver seat. I've been looking at the wiring diagram for this issue as well, and the only other thing I can think of that isn't a computer involving issue would be the thermo switch. But it seems like both fans should be coming on in that case, and it's definitely only the one fan that is coming on.

Have a 2001 Subaru Legacy GT, 5 speed manual, 194,000 miles.
A few months ago, I started noticing that my cooling fans are running more often. Even when it is cold out and the temperature gauge was at normal temperature. The fans would turn on, and just keep running. Obviously, they would turn off when I shut the car off, but if the car is on, they will stay on. However, I found a trick to get them to turn off. If I am in neutral, and I race the engine up to around 3000 RPM's or so for about 10 seconds, and let it come back down to idle speed, the fans are now off. Works almost every time, not just a coincidence.
I know my car, and this has never done this before. I know it is not normal. I have replaced the following- thermostat, coolant temperature sensor, flushed the system, changed the fan relays, and most recently, I put a brand new Subaru radiator in. All of this, and the issue is still there. I am beginning to wonder if it is the water pump. Coolant not circulating fast enough, so the fans come on to cool down, but when I race the engine, the water pump works harder circulating coolant faster? Also recently, the temp gauge starts to climb going up long steep grades. If I pull over and race the engine, the temp gauge drops almost immediately back to normal. The pump is not leaking or making any noise, so I'm not sure if it could go bad any other way.

Drove my son's '01 Santa Fe and the AC is not cooling. The compressor seems to be working but there is a clicking sound coming from under the dash on the passengers side. The clicking is louder when you turn up the speed of the fan. The coolant does not need to be charged.

I'm driving a 2002 Santa Fe (4WD, 6-cyl) without AC. The problem is that the compressor is dead and needs to be replaced - it was diagnosed by both a Hyundai dealership and a local repair shop. I understand that when replacing the compressor, you want to replace the receiver/drier and expansion valve and clean the system to remove any metal shards in circulation. What is unclear is whether or not the condenser also needs to be replaced. This is complicated by the fact that the receiver/drier is physically a part of the condenser. While shopping around, some repair shops said I would have to replace the condenser as well, and others did not.
My questions are these:
- Can I just have the desiccant bag inside the drier replaced, or do I need to replace the entire condenser + receiver/drier unit?
- If replacing just the desiccant bag is an option, is it still smarter to replace the condenser as well in case there is compressor debris lodged in there that can't be flushed?

I have a 2006 2.4l Santa Fe, has been diagnosed with failing ac compressor. Quoted exorbitant amount of money to replace. As far as I know, this vehicle was available without the ac option, and at this point I don't car if I have it or not, looking for the cheapest fix. Can I bypass with a shorter belt? Does it need to be removed completely, and if so, can it be done without affecting anything else?

My mother in law has a Santa Fe 2004 with a ~2.4. The AC compressor quit working over the winter. The AC compressor does not react to turning on the AC button.
I checked the fuses. I also tried changing out the AC relay with another one and it still didn't respond. The relay also didn't sound as though it was clicking over. The AC indiacator light is working.
Could it be the actual button has failed or is there a way to check if the button is functioning?
How does the compressor know to engage? Is there a place I can test 12v at the compressor?

2004 Santa Fe (GLS 2.7L)
First off, the A/C has not worked since I bought the vehicle used. I have checked all the SMALL fuses (10-25 amp) that can be easily determined good or bad, both under the dash and under the hood, so this basically rules that out (right?). I was unsure of how to check the larger, plug-like fuses under the hood. I am about 85% sure the A/C compressor does not engage when the A/C switch is pushed (yes, the light on the A/C button inside does come on and stay on). This is because I am unsure of which pulley is the A/C compressor and where exactly it is located under the hood. My research showed that it should be the bottom-right pulley when looking at the car from the passenger side, but I could be wrong on this. The fact that I just moved to Florida from the midwest a few weeks ago makes this a rather urgent problem.
Next, after a recent oil change there has been a harsh knocking, diesel-like noise coming from the front-right (passenger) side under the hood. Further inspection seems to show that it is coming from the area of the A/C compressor (or where I'm assuming it is). Again, I'm wondering if this is related to the A/C compressor. This noise is not normal, and has only recently begun to be a problem. It happens during initial startup, can be heard during acceleration, and only seems to quiet down a bit during idling after the vehicle has been warmed up. But it is now always present.
Finally, when fueling I have noticed that filling the car prevents it from starting! I am forced to shift into neutral and rev the car while simultaneously turning the ignition. This does the job, and once the car is started, it runs fine and the problem only ever happens immediately after fueling...any thoughts from the more "mechanically-inclined" out.

I have a '03 V6 3.5 Santa Fe. The clutch on the AC compressor went out and was making a loud racket. When I was pulling the compressor off I noticed the wire harness connection to the compressor was damaged. Either by me or previous change.
So the end of the harness on the car side is damaged. Can a new one be purchased and spliced? I cannot see where it goes to see if it can be replaced.

After 9 solid years of service, my a/c compressor finally failed. According to the shop, its leaking at the center seam of the compressor. If the system is charged, then the compressor will operate until the low pressure switch shuts it down. My question is this: Can this compressor be rebuilt? If so, where can I get the parts (I'm assuming the shaft seal is leaking).
Also, a quick search on eBay provides several compressors that fit my car; however, some of them are listed as HS-17 compressors and others are HS-18. My car (according to the A/C sticker on the hood) says I have an HS-18 compressor. Are these two interchangeable? I'm asking because if the current compressor can't be rebuilt, then I will have to buy either a reman. or new unit.

Recently I began hearing noise such as a rattle on the right front of the vehicle. It is a 2003 SF 2.7L front wheel drive with almost 180k mi. At first I thought the noise was from the Serp belt tensioner. Now I believe it originates from the compressor clutch.
Does the a/c clutch have a history with its bearings ? Is the clutch replaceable on the compressor or is this a single unit replacement ?

My daughter has a 02 stang with the 3.8 . the other day she complained that her ac was not cooling so i put my gauges on it and checked the freon. the compressor was on and the low side showed about 35 and high side was about 225. it was cooling good, now today it was not cooling at all and the compressor was not on so i jumped the pressure switch on the dryer and it came on, pulled the jumper and plugged it back in and compressor came back on and started cooling. I might have a bad pressure switch also about the pressures could the orfice tube be getting stopped up. this car must have had ac problems before with the previous owner because someone has wired the ac clutch 12v+ wire to the outlet side of the pressure switch and the 12v- side to a ground screw.

I have an 05 Prius with 53k miles and the ac just recently stopped working. The blower fan still comes on, but neither the compressor nor condenser cooling fan will come on. I've checked the fuses and relays, and they check out ok. I'm hoping there may be one I missed? It just stopped working with no warning signs. What could be causing this? If the compressor was bad, the condenser fan would still work, right? I'm fearing it's the ac inverter. Do the symptoms match?

We have a 2003 Nissan frontier pickup (automatic).The AC recently stopped cooling, but the fan works. It was cooling perfectly great when all of a sudden, it stopped. If we turn the AC on, the compressor (I'm guessing) starts to click and continues to click until turned off. (started to grind under hood). It's not a rattle, definitely a click as if it wants to turn on but can't make the electrical connection. It kind of sounds like when a starter has gone bad and it clicks. Except, it does it repetitively until turned off. This doesn't happen if we turn on the fan but leave the AC off. Does it sound like the compressor went out? How can we troubleshoot it?

I have a 98 Grand am with the 2.5 and recently noticed first that the a/c compressor wasn't coming on. It had freon added recently and did okay for a few days,then no compressor coming on again. (It still has freon) Then I noticed that the engine cooling fan was running as long as the engine is running on cold or hot engine with heat controls off (I know the compressor runs when on on defrost position as well as a/c). I thought the 2 problems may be related? I found 5 relays at R/F strut tower and the 3rd relay cut off the fan,so I swapped some of the relays, but made no difference.The fan only quits when I turn the engine off, and I can't get the a/c compressor to come. I don't if I have 2 seperate problems or not. Could it be the PCM?

The issue I'm having is the A/C. When I got the truck the A/C was completely freezing. Recently however, the compressor was having issues not engaging and I fixed that by simply plugging the cord to the accumulator thing. . Now the compressor engages, but is not cooling really at all. It is an old truck and the compressor is a little worn from what I see maybe 2mm space when not engaged. I checked the levels of freon/coolant with a gauge and the amount is perfectly fine. Plus there seems to be no leaks.

2007 Ford F150 half-ton. No cooling of air at the outlet of the ductwork. Freon charge is good, I watched the tech pull the system down and hold it for the prescribed time period. Compressor will not start. I am being told that this means a failed compressor, but I am of the idea that the pressure switch for low pressure must have failed, or the orifice is stopped up. I am also being told that the compressor, evaporator, and orifice tube needs replaced in order to remedy this issue. The counter man at my local parts house cannot find in his computer any pressure switches, kinda making me think that everything is in the unit. In short, if I can avoid buying the compressor, I would like to.

Other than lack of cooling ,will a failed ac compressor on a 2006 Volkswagen Beetle cause other issues if not repaired? it is a convertible.

My 6.0 is cooling poorly . Clutch is engaging , condenser free of obstructions, static charge L95 , H. 105. Running psi at 94 ambient is 50 and 225. This morning with cooler ambient in mid 70's it was 40 and 200. I'm thinking compressor .
