Heater ac panel


There will be a high blower relay and resister made together ,this is located very close to the blower motor,it mounts on the out side of the blower case,but actually goes inside the blower motor case to stay cool.This is more likely the cause of your problem.

How to retrieve DTC:
The heater control panel has self-diagnosis function. To run the self-diagnosis function, do the following:
1.Turn the blower fan OFF.
2.Press and hold the recirculation control switch and the rear window defogger switch down.
3.Turn the ignition switch ON (ll).
4.Release both switches. The recirculation indicator and the rear window defogger indicators come on. The recirculation indicator goes off 3 seconds later and the A/C indicator comes on, then the self-diagnosis will begin. About 10 seconds later, the self-diagnosis will finish and the A/C indicator goes off.
- If any trouble is found, the recirculation indicator blinks the diagnostic trouble code (DTC) to indicate a faulty circuit or component.
- If the system is ok, the recirculation indicator stays off.

My 2003 impala ac blower wont turn off when i turn it to off?


Does it turn off when you turn ignition key off? If so, sounds like your heater/ac control ***'y has a bad on-off switch.

When I turn my car off the air conditioner still runs-I needed a jump the other day because it ran all night and wore the battery down.


OK, if the relay for the A/C fan is bad, then the radiator's fan will keep running after turning off the ignition. Also, if the fan for ventilation of the A/C in the cabin stays on after the ignition is turned off, the relay for that is bad.

Good luck on this repair.

A/c fan blows without car turned on or key in ignition


Either you have connected your wiring incorrectly, recheck all of your wiring connections, Or the power supply for the fan is coming straight from the battery instead of running through the switched relay, most likely the relay is stuck closed allowing the fan to stay on.

Blower stays on when ignition is turned of.


The sensor is probably defective as it keeps the fan on regardless of water temp. Get it replaced.

AC BLOWER FAN STAYS ON IN MY HUMMER H2 (2003) AFTER IGNITION IS SWITCHED OFF- WHY WOULD THIS OCCUR?...


When does it go off (the fan). I assume it does, sooner or later, go off? Some blowers (high-end vehicles) stay on a little longer to clear moisture, but if this just started (hasn't happened since day one) then I would assume it is a short (pray it isn't) or the blower cutoff relay/blower motor relay. If neither relay is available for that car, it could be built-in to the motor. Then, try to unhook the motor and put a tester on the connection plug going into the motor and see if you can get power with the car on, and watch it disappear once the car is turned off, that indicates it is the motor or the resistor atop the motor.

Cruse control


Does your blower fan work on your heater/ac or your rear defrost work it could be the igniton switch were you put the key in. Turn the car on and off several times once you notice the cruise will not work and see if it starts to work if it does than it is the ignition switch this just happen to my 2003 century.
