AC/Vent/Heater Only On High....

[gabe8496]

What would cause any of these functions to work on HIGH? If I set it to low, Med...it feels as they are off...but set to high and they work.

Could this also "possibly" cause my ac compressor clutch to burn up? I've replaced the ac compressor and for the 2nd straight time, the little black discs that hold the metal spacer between the pulley/clutch begins to melt and then the spacer becomes free.

Any ideas would be greatly appreciated.

Someone else here had the same problem, I suggested the switch, dont know if that worked or not for them? I dobut the AC compressor has anything to do with it.

If you AC keeps goin bad just get a AC delete for it. Wont keep costing you money to fix it, and a lil less going on in the engine bay.
