In this episode of the "What a Nightmare" series, The Greg tackles the air conditioning system on his beloved 1997 Chevy Tahoe 4WD four door, with no rear air.
The Problem: warm air coming out of the vents when the AC is on.
Troubleshooting: with the car off and not driven for a couple of hours I hooked up my trusty Harbor Freight special AC gauges and the reading was 0 on the high side (red hose) and 0 on the low side (blue hose).
By the way the hoses will only hook up to the right inlets as they are of different sizes. Also the vertical high pressure nipple (if you will) is physically "higher" than the horizontal low pressure one which is below or "lower" on the hoses on top of the AC compressor.
Normal reading would be around 125 per side with the system equalized after the vehicle has been sitting for about an hour (to be on the safe side)
So I am [ahem] low on AC juice, actually I am completely out, which unless someone "evacuated" my system when I wasn't looking, means there is a leak somewhere.
