    A/C Compressor Lost all of it's oil last night.

    So unfortunately, my a/c system that I had completely rebuilt a few months back failed last night. The one night I had to park it outside, I came back out and found a puddle of trans green oil under it. Opened the hood and the compressor let out pretty much all of it's oil. It seems so...

    2 Problems - Engine Not Warming Up To Operating Temperature

    I have a 1994 GMC Yukon. Engine is a L31R crate (based on 96+ vortec) that is stock aside from aluminum intake and headers. I live in Canada where it's normal to get -30 c / -22 f. I'm having a hard time getting it up to operating temperature in the winter. It seems to want to stay around...

    Air Conditioning Over Charged?

Unfortunately, it's looking like it's still not working properly. After about 10-15 minutes of driving with the air conditioning on, the...

    I have a 1994 Yukon. The cab mount bolt just behind the driver's side seat broke and I'm unable to access it properly from underneath. I've been told that there is an inspection plate underneath the carpet and I can access the bolt from the top. Before I begin to disassemble things, I want to...

    Air Conditioning Fuse Keeps Blowing

    Just replaced the compressor and pressure switch on a 94 Yukon. The A/C runs well for a short time but blows a fuse. Any ideas on what the issue may be?

    Problem with cab mount bolts.

    I just purchased my first GMT400 truck. A 1994 2 door GMC Yukon. I needed something to kick my feet on due to all the snow around so I bought some nerf bars / side steps. They mount right on the existing cab mounts. To install them, I needed to remove the bolts that go through and secure the...
