I had the same problem and just fixed it. I looked behing the door that opens and shuts when you turn your heat /ac knob on and off (it's located behind the glove compartment) and there was a mass of insulation (probably from a mouse) balled up and blocking the blower from turning. I removed all of it and it works fine.

Ase mechanic:

Sounds like a problem with the front blower motor. there is a blower motor resistor for the front blower motor that controls the speed of the blower and tends to go bad or fry out the blower motor. thats the most likely scenerio since you stated the control head was lighting up and responded to button changes.

    sometimes the resistor is the problem and either item can be difficult to change. they are under the glove box "usually" and under some panels. most are tiny screws that are either 7mm or 9/32

No air in front but i have air in rear is there a belt in front ??


Can you hear the front ac/heater fan? They use the same AC compressor so that should be okay. The fan switches fail quite often on those. That controls how much air is pushed by the fan for AC, heat and defrost. The switch is attached to the fan knob on the dash.

My climate control only blows out cold air but the rear climate control works as it should


Could be the controller or a faulty blend door.
The blend doors direct air thru the heater core and evaporator along with the vents. The controller uses electric motors to change the direction of air flow.

What's your problem?I have a 1996 Chevrolet Suburban. The AC is blowing out hot air. I have had the truck for 6 years, every Summer its the same thing. The ac does not get cold, I take it to the m


To clarify - - if the truck has rear and heat, you have two heater cores and two evaporator cores. The evap cores carry the freon.
If the leak is in the evap core in the front, the price is probably right.

You are going to need to use a multimeter and have a professional test the relay voltages. This should probably only take an hour, make sure they have the proper electrical schematic for your vehicle year make and model.

1999 Suburban, A/C on warm air from front vents, cold air in rear


The car uses the same freon in the front as it does in the rear. If the rear a/c is working, you either have a plugged evaporator in the front unit, or perhaps a bad heater switch. Try switching the heater to hot and see if it blows even warmer air from the front vents. If so, the heater switch is working and then it sounds like a plugged evaporator or maybe a plugged orifice tube. That is a good place to start looking. Hope this helps.
