Silverado :: 2001 - AC System Making Lot Of Noise
Jul 14, 2015
I have a 2001 Silverado 5.3 liter extended cab. Recently have been having issues with the A/C system making lots of noise. I have identified the noise to two spots and I believe 2 actuators..
1) behind the glove box to the fresh air / recirc door there is a constant clicking / grinding noise. Toggling the recirc button causes the noise to oscillate and the recirc door can be moved by hand, so seems the actuator is basically gone...
2) When the mode is to face only there is a gurgling / clicking noise. When I move the mode selector a little bit off of face only, the noise seems to stop.
I have been looking and looking for a solid write up for the recirc door, can't even seem to find anything that is solid on the part number for that. Seems like I could probably get my hand up behind the glove box to take off that actuator and get the part number, read a couple of write ups that seem to suggest that it is incredibly tight and hard to get to, but it can be done.
Wondering if I just remove the top of the dash while going after the mode door actuator to make life easier? And do I need to get in there with the blend door actuator while I am doing the other two? No dual climate control, so does that leave me with only three actuators? I have the "automatic" a/c controls which are knobs on the dash, I believe these are automatic, not the slides that I believe are referred to as manual?

I was at the bank today and when I put it in reverse to back out, the car jolted and then it rolled forward slightly while at the same time sounding like there was grinding. I immediately put it back into park and the noise stopped. Then I tried to reverse again and it started making a clicking and whining noise and wouldn't back up. It sounded like it went into gear but it won't move. I was able to get it pushed out and the drive still worked. So I was going down the road and got up to speed and the shifting was significantly delayed.
It's an automatic by the way. So I tried to take it on the highway and it won't shift out of 2nd gear or 3rd. I know for a fact that overdrive isn't working so i'm doing 50mph down the road and hitting 2500 RPM. I don't know what the deal is but for about 8 months there has been a rumbling vibration when it tries to go into overdrive and when I accelerate quickly I force it to downshift and the rumbling goes away but it still shifted into overdrive when it got passed the rumbling and vibration. It's a 1997 C1500 2WD 5.7L Silverado.

My climatic A/C system is making a buzzing noise when I press the recirc button. After I press the button it sounds like the recirc flaps are trying to actuate but are broken or the motor is not working. It makes two different distinct noises when going into recirc and out of recirc. How hard this is to fix since I'm sure it is located in the dash.

A couple of times in the past few months I've been listening to music and a shrill sound has come through the system. It doesn't stop and I have to turn if off and back on to get it to go away. This has happened with both Sirius and my iPod. Yesterday the song was showing in the display but no sound was coming out. The volume didn't work. I had to stop/restart the car and it came on.

Trying to load the CD ... I put in 6 discs I've tried them label up, label down, Compact Disc Digital Audio, and regular CD-RI hear the changer making noise when installed. The system won't play the CDs. It just says "No CD" At one point it put up a "Bluetooth connectivity problem" message. The rest of nav sys seems to work. 2005 Nav Sys Factory Changer. I've never used it and just got the car.

So the problem seems to be the climatronic system is constantly trying to adjust the temperature but the problem is that the motors or servos are making an annoying ticking noise as it adjusts. I already had the blend door assembly replaced but the noise is still there. My Touareg has climatronic and doesn't make any noise, so don't believe I should be getting this noise in my Passat. Service advisor claims its normal to make some noise since his Passat does the same thing, but I don't buy that. So who has had the same issue and got it fixed properly? What did they replace?

I have a 2001 Chevy Prizm that I just had the front pipe replaced on. It was not accelerating well and making noise. New front pipe and it feels like a new car. The check engine light came on. i cleared the code, drove it for a day or so, and the light is back on. My exhaust mechanic says we don't really need to worry about the cat con hurting our engine unless we see a decrease in performance. Are there any mechanics out there who would say that is true. The car has 160,000 miles and we want to see it go another 100,000 or so, and not do anything to damage the engine.

My 2001 SL2 is making a lot of rattling noise. I think I have isolated it to the A/C compressor. I noticed that on the back side of the A/C clutch the plate where the signal wire connects into is very loose when the A/C is not on. The noise seems to be loudest when the A/C is not on. But when I turn on the A/C, that plate tightens up. But the noise continues. Could it just be the A/C clutch or a bearing or something? Or is the noise coming from somewhere not even related to the A/C? The A/C still works really well. I just notice the noise.

My girlfriends car is making noise while turning and I'm sure it is cv axles i have done them before on my old jetta so I'm sure i can do it.
Question is I'm just not sure which ones she needs it is a automatic and I don't see any wires going to the caliper but i have not removed the wheel to check and the dealer said that the front is abs and the rear is not so I am lost here is the vin.

2004 Santa Fe AC fan has started making a rattling noise. It gets louder when the fan is turned up. How can I check it? Noise seems to be under the glove box.

Okay, I have a 2001 Saturn SC2 with 180,000 miles racked up. Lately, when I'm out driving, it sounds like a small prop plane. Yet, when I move the steering wheel just a bit to the left, the noise vanishes, until I steer back toward the center.
I'm dreading taking it to my mechanic, even though the shop is quite good. What this might be before I head in to the Temple of Doom?

Ok, probably about 1/3 times i start my 96 f150 4.9 with true duals, the left pipe has a higher pitched howling noise, its a steady tone whether I rev the truck up or not it just gets louder. It will do it for about 6 seconds and then stop. The truck doesn't run badly because of it, but i took her to autozone to get her scanned and they said that the oxygen sensor on the first manifold bank has a slow response on startup. Is that what causes this strange noise, I don't even know how it would make it, it sounds much different from the engine. The right pipe doesn't do anything.

2001 Buick Regal , 125000 miles ..
A couple weeks ago I notice that my car has started making some noise and has become a rough drive. Whenever I rev, especially between 0-30 mph, its like a mini jackhammer, or a sputtering/rumbling sound when I drive.
What it could be, and what I should do?

I charged my AC a few weeks ago. After I added oil it began to make noise. Like metal on metal or a bad bearing. Could be the clutch pulley, bad bearing from what I've read. I don't want to replace it, nor do I want to spend the time and money putting in a bypass pully. I'd like to simply bypass the AC compressor by putting a shorter belt on. Problem is I can't seem to find any clear info on how and what size belt to use. I see a few saying it can be done and one saying it can't. Also, is the 2.4 the same as the 3.0 in regards to the belt diagram?I need to fix this asap, before it seizes up and I lose the belt or damage other stuff.

I have a 98 K1500 Z71, having trouble with a ABS brakes going off every time I come to a stop, occasionally I don't even have to push on the brake just turn a corner and they go off. The brake light or the ABS light on the dash don't light up. I have taken the speed sensors off front axles cleaned then and sanded the rust off where they mount and still the same problem. Also, in the world of OBD scan tools, I know what ABS stands for ( brakes ) but what SRS stands for?

Any fix for the rear brake noise I am getting on a 2001 Elantra. I pulled the drums off and inspected the drums and shoes all looks fine. Then I adjusted the brakes cleaned everything and still get noise. It occurs as the vehicle is coming to a stop last 10mph to stop.

So I recently bought a Hyundai Elantra Gt 2003 that I totally love. But ever since I bought it, it struggles to turn on. It makes a cranking noise before it turns on, and it takes about 2 to 3 times for it to fully turn on. I changed the crank shaft sensor and the fuel pump. What can it be?

I just bought a b5.5 Passat 5-speed glx... fully loaded, a nice package. It has 67k. I just did the timing belt, valve cover gaskets, and cam tensioner adjuster gaskets. I park on a slanted driveway so the car sits on an angle all night. Only when i start up first in the morning, it makes the noise as if the oil isn't rushing up through the engine all the way, and makes the clicking noise in the motor..but any other startup throughout the day is fine.
Only the first in the am. you guys think its just because i park on a hill type driveway? What else it could be.. After I start driving for like 10 minutes, I also hear like a little whining/vacuum noise more noticeably in first gear, idk if that has anything to do with it? I haven't checked the oil level since i got the car back from the shop, but i know i should maybe they forgot to add an extra quart or something.

Currently own a 2001 vw golf gls 2.0 with 223000 kms on it. used specifically as a beater car. Noticed that it has all of a sudden started to make a creaking sound when it has run for a long period of time. Stops when you hit a speed of around 50 kms/hr.

I got a call from the wife at work telling me the vehicle was making a loud noise when being driven. I told her it was a bit hard for me to diagnose since I was at work and to leave it parked till I got home. She really had to go out so she decided to drive it a short distance and come home.
I got home and discovered the drivers side spring was sitting on top of the inside of the front tire. The spring had done a superb machining job of the tire tread to the point I was amazed that the tire still held air. Anyway long story short the beast is in the shop having both front springs and struts,tires etc. being replaced. The spring actually broke.
I just bring this to the group as I did a search on google and this is not an uncommon, occurrence on these santys. We /she are just lucky this happened at a low rate of speed,as a highway speed incident like this would not have been pretty.
