My AC control module went black while I was driving and won’t come on, but my heater is still running and I can’t even turn it off. I’m not exactly sure what to do since I already replaced the fuses. any suggestions?

Hey ICONDELTA,

A TSB (technical service bulletin) is applicable for the AC controls.

Try disconnection and reconnecting the battery and retest.

If no change we can run through checking power/ground to the AC controls.

Hope that helps, let me know how it goes.

Regards, Joe
