Re: Climate control / HVAC dead, stuck on full defrost
Hi,
I had a s seemingly dead HVAC, but it turned out to be a faulty T(Timer)CU causing a voltage drop. Unplugging the TCU made the HVAC work again. I didn't have the blower stuck on, or any lights on the control panel. If you pull the unit, it's probably worth checking power and ground before installing the donar unit.
Good luck!
Ian.
