a/c

G'Day! Can answer if the green o-rings are supposed to replace the aluminum washers with the black rubber core? I ask for a couple reasons. First, everywhere I look, the green o-rings are plentiful while the others have to be special ordered. Secondly, I am having a hell of a time getting my...

My AC compressor on my 2003 Tahoe 4.8l wont engage. Here’s what Ive done so far: -replaced low pressure switch located on accumulator and checked wiring. I have 4.8 volts at the switch -replaced oriface tube -vacuumed system and added as much freon as I could (almost 3 - 12oz cans) with the...

2009 Tahoe / Police SSO with rear A/C unit. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> My current controller is the non-digital version. P/N 20787116, Four color coded plugs, Green / Beige / Blue / Brown plug into the rear of the controller.. Does anyone know the appropriate digital...

I have a 1995 Hoe LS 4dr/4wd I'm having some issues with. First question would be, is it feasible to take out the compressor entirely and use a shorter surpentine? If so how long of a belt would I need. I don't need AC and a little better MPG would be nice

My Tahoe blew cold air up till this summer. It has dual front climate control. I tried to refill it and it still doesn't blow cold air. I'm at a loss. The compressor I don't think is spinning. The belt spins around it but I don't think it moves. I'm not to familier with the A/C system. So I hope...

I have a 99 Tahoe LS 5.7L with rear A/C. Have a leak in the high pressure line. I purchased a high and low rubber pressure lines to run to the back. The problem I have is the down tube on the evaporator got boogered up. It is 8-10" long has a few bends, but is removable. I cannot find a...

Hi, I have a 1998 Yukon 4x4 with rear a/c. Ever since I purchased it 11 years ago, the a/c has slowly been getting worse; And has always had a slight leak. It was tolerable until last year when the front and rear a/c started blowing hot air. This year, I added a little freon (it was...

I have 04 tahoe, I start my tahoe and instantly everything sounds different. The idle is really low, my exhaust isn't loud like usual. And it feels like it's running out of gas.,i let it idle for awhile and it goes up and down. If I rev the motor, my oil gauge goes up and when released it...

Until today, a/c ran nice and cold. All of a sudden, front a/c stopped blowing any cool air. But the kicker is that the rear a/c still blows very cold air. any thoughts on the source of the issue? I'm hoping it's a simple fix. Keeping my fingers crossed.

My interior fan will stop blowing completely, on all settings, (a/c, heat, normal) It doesn't happen very often, maybe once a week (I drive about 350 miles/week), but it will stop, and then start back up on its own. I am not sure if this is the cause, but the very first time it started...

I am a new owner of a 96 Tahoe. i cannot get my ac to work. i got it checked for free at place and they drained the whole system. told me to put in 4 bottles of freon. it wouldn't take any. i checked all fuses and the relay but everything was OK, put new fuses and relays in just in case, also a...

I have a 1994 Yukon and ever since I got it I have had a rather weird problem. When I run the A/C, a/c does work to a point, the truck will heat up quick and keep going past the 210 degree mark when I am stopped or running the A/C in high and just doing normal around town driving. When I stopped...

The a/c blower on my 99 Tahoe quit working on low and medium speeds but would workfine on high. Next it was intermittent on high and now it doesn't blow at all. I suspect it is a relay but I can't find the a/c heater blower relay. I checked the fuse / relay box in the engine compartment there...
