Re: 2012 GMC Acadia SLT

After researching a little, I found that this problem normally means the system is low on refrigerant but the weird thing is that I just charged the system about 2 months ago. Would this mean a bad leak? Sounds like a leak to me as well. Have a real AC shop find the leak for you. Most likely GM add...

Re: 2008 Mazda 3 troubleshooting

2008 Mazda 3 2.3L Replaced old A/C Compressor and dryer due to the old compressor pulling a higher load than normal when engaged. What does "pulling a higher load than normal when engaged" mean ? 90F. At 1500 rpm the low is 27psi and the high is 225psi. Check your electric cooling fans, e...

Re: Finding leak in r134 conversion - tried UV... sniffer next?

One can try to identify evaporator leaks by using a sniffer in the vents or at the condensate drain tube without removing the evaporator case or dashboard. However, about 15 years ago I confirmed a leak in my 1988 Mazda B2200 truck evaporator using plain old soap bubbles. So that's also a good techn...

Re: 1998 Chevy Suburban Won't Cool Over 90 Degrees outside

See if bohica2xo in Las Vegas is willing to work on this. We've had 1994 Suburban and still have 2005 Yukon with dual AC in Arizona, both factory R134a, and the systems do cool well.

Re: 2006 denali cooling problem

Check the front blower fan for operation. Also there are like three solenoid valves under the dash that direct the air flow, maybe the air is being directed to the windshield (defrost) or under the dash (heat). I guess another issue could be a clogged cabin filter (if your 2006 has one) or debris in...

Re: No low pressure

Just thought I’d post a final report on this. Had it finished at a local shop. Here’s what was found. Blocked expansion valve. Dryer had the desiccant loose inside which is what plugged the expansion valve. You could here it rattle. Also a leaky oring on the condensor. New valve, dryer and recharge...

Re: Mechanical Fan AC delay

I'm in Phx too. Your seats, dashboard, interior are all 150-160F after sitting in the sun. That heat needs to be removed, sounds like typical Phx AC operation.

Re: Compressor won’t stay running.

It's possible that your manifold gauge hook-ups aren't depressing the port's Shrader valves, which will prevent refrigerant from entering the system. If you have the type of connectors with the small blue and red thumb-wheels, ensure that they're rotated all the way CLOCKWISE after connecting them ...

Re: 2010 GMC Sierra AC Issue

So far it's looking like it was just low on refrigerant. I added about 6-8 oz. of R-134a yesterday. I noticed before I added it that the low pressure side had some frost on the line and the drier wasn't really sweating. It wasn't freezing over, just a light frost. The AC had been running for probab...

Don't do more until you buy real gauge set or get Autozone loaner.

I sure hope that you didn't add refrigerant that contained SEALANT !
