ACC issue, Stuck on high

A few days ago I went to turn the heat down on the ACC. It's stuck on high, doesn't matter what combo of settings I turn on, the fan just kicks everything out on high. I even tried disconnecting the batter and running the ACC fault test. The only way to get it to turn off is to pull the 30 amp fuse for it.

What do you guys think it would be? How hard, and how expensive is this issue to fix?

How hard are they to remove? I know this is a noob question but if I took it out and cleaned it would that maybe help?

No, it won't. the cheapest way to fix it is to order a new resistor (transistor) for it. That's what goes bad in it. About $15 and some solder work. You could also buy a used controller unit for about $50.

Buy a used one, install.

Fix the original, even if you have to find a buddy to solder it. Put it on the shelf in case you need it later.

I'm kicking myself for not saving any of these from my parts cars.

Heat stuck on

I kind of have the same issue but no matter what temp I set me ACC to it always blows out hot air. Do you think it is the flap motor that is dead and is stuck in the heat position?
