Question about 1999 Chevrolet Tahoe
Just bought it and while the unit blows and it soiunds like the compressor kicks in...it's not cold at all. I have a cheap set of guages, and after checking...the pressure was waaay high. I let a bunch out,....below the green line anyways....then added a little to get it where it supposed to be on the guage....still not cold

the 100% for sure cause of this problem is the sending unit for the fuel guage, it is located in the gas tank. U may have to replace the fuel pump module to get the sending unit, as a rule they are one piece, if u have over 100,000 miles that is a good idea anyway.

Probably the electric clutch of the compressor is not working. This is the part that uses the power generated from the drive belt to drive the compressor. Normally if this is working, you would hear a sound in the engine compartment once you turn on the ac. Otherwise you may have only the AC blower spinning. If they check out OK, the thermostat may not be working. Your AC will not engage because it may be getting the wrong signal thermostat.

Its a leak ...probably concealed like in an evap housing or rear air unit and lines (if it has that). Prob at this juncture I would remove all the freon and bring system into a vaccuum with a pump and see if it will hold vaccum for an extended period of time. A bad leak will not hold srong vacuum very long and much cheaper than wasting expensive and enviromental un0friendly refrigerants.

That "thing" is part of the compressor clutch. When it’s spinning the clutch is engaged, when it stops the compressor is off. If it’s constantly cycling, you probably don’t have enough freon in the system. But remember, however the gas escaped before, it will escape again, unless you fix the leak.
