hey guys,
so my heat and A/C wont wrk ive done everything i can think of from putting antifreeze in to switch the thermosat and the heater core nothing is working and my switch that makes the air come out of the front or the floor or the defrost wont work ethier any ideas of what it could be?
thanks guys

 

is the temp knob hard to tuen, did u check fuses

 

blower motor could be pooched...

 

yes knobs are hard to turn and dont stay in place they snap back to random places on the dail if that makes sense lol yes fuses are fine

 

^ yea that makes sense...
there are a few threads about the temperature control knob being hard to turn. If you changed the heater core out before, then this job will probably be about the same pain the ****.

 

I had the same problem. Mine was a voltage regulator that tells the blower how hard it should be blowing when set to the different speeds.
