My heater and a/c controls stopped working last night. All the fuses look good(kick panel and engine compartment). Any ideas?

thanks,
Craig

 

does the air not come on at all??if it doesn't work at all then your blower motor or blower motor control module is busted..if it only comes on at max then(which is turned all the way up to highest setting) then its a good chance it's your resister, that is busted. hopefully it's the resister, blower motor/and or module costs a arm and a leg and is a PITA to install..

 

If you have the ability to change HVAC settings...i.e. Auto, temp up or down.
then check relays, fuses, blower motor.

If the screen is back lit, but no LEDs are showing and also your dash temp reads (-22) or (--). If this is the case.

Check the kick panel fuses. Twist the fuse slightly clockwise or counter clockwise. If the heat kicks back on, then its the contraction of the contacts because its cold outside.

 

None of the buttons on the dash control panel have power.

The lcd screen is backlit, but that's all.

Wiggling and twisting fuses had no effect.

 

check the plugs on back of unit...

 

Specifically check the cigarette lighter fuse.

 

Problem solved. Blown cigarette lighter fuse.

Thank you Neucorp!!

 

This forum rocks! I have the exact same problem and now it's solved. Thank you all for the information.

 

I have the same problem like Craig - my heater and a/c doesn't produce any hot or cold air, although the fan is working fine. Furthermore, I don't have the fuse box diagram so I don't know where the a/c, heater, or cigarette lighter fuse is.

Please help me locate the a/c, heater, and cigartette lighter fuses. I really appriciate your help.

Thanks.

 

You can really just pull out and check all your fuses there really aren't that many. It's a blue 15A fuse though.
