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.

2004 CHEVY SUBURBAN FRONT A/C WORKS BUT THE REAR DOESN'T TURN ON


There is a blower motor control processor for the back blower - it takes input from the front control and the rear control and decides the fan speed. That processor could be faulty, or the blower motor, or a 30amp fuse in the engine compartment.
In the front system you have a controller and blend doors that direct air thru the heater core and evaporator. You would need to check the operation of those blend doors.

Where's the fuse for the AC on 98 Olds 88?


So what does the fuse that blows, protect?

You need a wiring diagram & start to test
the components most likely to cause a high
current draw & blown fuse.

Don't keep replacing it.

You know the fan control circuit works, but the
compressor doesn't stay on. Did you monitor
the compressor as the fuse blew?

May have a module for compressor & fan
If so one side failed
The compressor clutch could be bad

I hear loud noise when I turn on air conditioner in my 2001 Chevy Suburban, it only makes noise when I accellerate or push gas in park. No noise when I am idled. But air blows cold still.


Check for wear or other faults all of the following: The belt, fan clutch, Check A/C compressor&clutch for damage. Check A/C compressor for damaged or faulty temperature switch switching compressor off and on too rapidly, or low oil level.Check A/C hoses for metal A/C Lines vibrating against other components under the hood, or faulty blower motor bushings. Hope this helps you out.

2001 Chevy Suburban rear a/c warm front ice cold


I believe there is a expansion valve located on the back part of the air conditioner on the back right side i believe that could be the problem. I think if I am understanding you correctly, your back air is not as cool as it should be or not cold at all. Might want to check this. If I am not understanding you correctly please let me know again what your problem is.

1995 Chevy Suburban blows cold once charged then hours later hot


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.

A/C BLOWS COLD BUT COMPRESSOR IS NOISY WHEN ACCELERATING


it sounds as if the Bearing is out on the A/c compressor you can just replace the bearing and save a lot of money but you need the right tools to do this to get your air gap set right on the clutch again i suggest takeing it to a shop you can trust for the repair
