Why doesnt the air conditioning or heating work in my '92 Buick Lesabre?

Question:
I have a 92 buick lesabre. About four months ago my air conditioning stopped working. By that, I mean that it would blow air, but the air wouldnt be cold. Then yesterday my heater stopped working in the same way, so now my car blows the same temp air out the vents regardless of the setting. Any help narrowing down the source would be great!

The A/C problem and the heater problem are probably not related... but could be. They are both electrically controlled by the HIVAC control head. The cause of your A/C not blowing cold could be caused by alot of different things. The lack of heat also.
On your lack of heat issue.. There is something simple that you yourself may be able to check, that is, your coolant level in the radiator. If your coolant level is low (from a leak) there may not be enough coolant to circulate through the heater core and this may be the cause of your lack of heat. Make sure the engine is cold before attempting to check or have anyone else check the coolant level. If the coolant level is low
you will need to have the source of the leak fixed.
