Question:
I drive a 1999 F-150.
Crown Vic suitable for long distance travel?
About a week ago, my air conditioner stopped responding to any changes on the temperature knob. It makes no difference where the knob is. Whether it is set on the extreme hot or cold setting, the air comes out warm. Because I can't even get hot air and there was no decline in the A/C leading up to this, I am asuming the problem rests with the temperature knob or some compenent downstream of it.
I am hoping someone can give me some insight as to where I should start looking. Would this be caused by a failed potentiometer in the dial? Or maybe some actuator under the hood?
Where to find a wiring harness for Idle air temp. sensor, mine broke??
Thanks.

your truck uses vaccum pressure to move the fins regulating cold/how setting, so before you go and buy something new look under the dash and under the hood for broken or loose vaccum lines.Actually you have a stuck(broken) door actuator. it is under the dash in your a/c-heat case and yes you have to pull the dash to get to it. It sounds like the main door is stuck or broke in the center position.
Sounds like you have a problem with the heater/ac controller part and need to replace the "head assembly" on the dash. You can probably locate the whole assembly at a parts recycling center (wrecking yard). Should be a simple fix, just look at the new/used unit to see how it attaches.
