My 2002 Suburban 115k miles a/c warm


Please help if you know Suburban a/c problems. Thanks!



I may have actually lost some pressure when I added the small can, seems the static "after" is lower than "before". I am new to using one of these manifolds. I had a leak at the can, cheap walmart 134a can did not seal properly.

If the A/C system is related at all to the C5, check the vacuum line at the back of the intake manifold. If its cracked or some off, then the blend door my stick hot. At least thats what I remember when I had that problem with the C5. Could be I'm misremembering the fix though.

Thanks, it's not the blend door, I can hear it move and the under the hood symptoms (the lines not getting cold enough & hot enough) point elsewhere.

Froggy I had the a/c belt jump of the pulley on my C6 once, not sure if this may be your problem.

Thanks, my belt is fine & compressor cycle on/off.

Here is how I fixed it, start around 8:00 if you already watched the first video.
