air conditioning

New 2025 Encore GX Sport Touring. Hearing a hissing sound every 15 seconds when using AC.

Hi all, I’ve been running the air conditioning on Max AC I’ve noticed condensation building up on the outside windshield. It looks like some of the cold air is directed through the windshield vents and not fully through the mid vents causing that part of the windshield to get cold and build...

A month ago when I got the car, the a/c was blowing at a slower than usual rate. We replaced the blower motor resistor and that seemed to fix it, the fan was back up to correct speed. Then after 3-4 trips, the a/c shut off completely (nothing coming from fans at all). We replaced the a/c control...

I’ve recently noticed that the AC fan slows dramatically once my vehicle speed goes over 40mph. I am assuming this is not normal? Anyone else ever had this issue? Tbanks!! Rob

My 2005 Buick LeSabre recently had the AC go out and after some research, I believe it was due to the compressor seizing. It no longer blows cold air and there is a significant knocking / screeching noise if it is turned on, in addition to the engine RPM's being reduced. Current estimates for...

Hello! I recently came into possession of a 2005 Buick LeSabre Custom. It's my first car, and in all honesty, I'm loving how comfy it is. It has a majority of its suspension recently replaced, so many of those issues are gone, but I'm running into other trouble. I work at an auto parts store...

Does anyone have any experience diagnosing the AC buzzing sound in the cabin of these cars? There was an older thread with a similar question but it no one really reached a consensus on the solution. One person said it was fixed after adjusting the AC lines so that they were further away from...

Hi, Earlier this week my girlfriends car got rear ended and naturally it belonged to her grandma and holds a lot of sentimental value. Side note, my girlfriends grandma passed and she's selling me the car since it reminds her of her grandma so that way she knows it will be taken care of but she...

Compressor kicks on and off, pressure on AC Pro was right, ac pro only checks high pressure side though I believe... It has manual dual zone controls, which I already replaced (with a used unit) The heat is super hot, but when it's on max ac it still feels a little warm, and having AC on or off...

I recently purchased a 2019 Buick Encore. I live in Florida and in the early morning and into the night I have a condensation problem on the outside of the window. The AC blows through the defrost constantly. The defrost feature does not seal off like every vehicle I have ever had. The Service...

Does anyone know the low and high side port pressures for a 1998 Buick century air conditioning.

Hi, all! Just discovered this forum. I've a host of issues that I hope y'all can help me with, but this is the most important one, so I'll start here. Car: 1999 Regal LS, just turned 100,000 miles (!). Engine, drive train reliable, but anything to do with the body, total crap. Me: Been...

Hi - 2014 Encore, whenever the fan for heat or A/C is up more than one notch, there's a super high pitched squeaking / whistling sound...any suggestions on how to fix / lubricate or even where to look? Am not a car person, but am pretty handy.

1998 Buick Park Avenue Ultra Issue started with no cold air. In the past year I have had issues with that & have added stop leak and freon. A couple times I again added freon when it would start not working again. The last time, was several months ago & it has held quite well. I thought I...

It is hot out here and of course the AC doesn't work! It all started when I noticed the AC clutch was leaving filings and the compressor was no longer turning. I bought the tool and the parts and replaced the clutch and coil. It does not engage. I don't seem to get a voltage reading at the...

Hi, Found the forum via google while trying to figure this out. Specifically, a thread about replacing the heater core on a 1994, which I believe is somewhat redesigned from the 1993 - I know they changed the engine and parts of the AC system. Can I do the evap core without pulling the...

My vent flow only switches from defrost to middle and lower no matter what the heater head unit says. Thanks

Can someone tell me where the ac low pressure switch is located on my 2004 Lesabre? I'm thinking that this might be the problem. Thanks,Jim

2004 lesabre There is no voltage on the wire cable going to the ac compressor. I have replaced the relay and check the fuse but still there is no voltage going to the relay. Yet I can short out the relay and the clutch will engage but there is no cold air. It worked fine last summer. does...
