Climate control problem: Blower stuck on, CC panel not working
Hi there. Yesterday I got in my '96 850 GLT, turned it on, and discovered a problem. The blower is stuck on high and the CC panel doesn't respond.
I have ECC. Like I said, the blower is stuck on high, blowing cool air (as cool as it could get without the AC being on) as hard as it can. The air only comes through the top vents that I can tell. The recirculate switch doesn't work (I suspect it's drawing in fresh air), the AC switch doesn't work, and blower speed slider doesn't work, and temperature controls don't work, and the vent selector dial doesn't work.
The CC panel is getting power, as all of the background lights work. However, neither the recirculate light (when the recirc. button is engaged) nor the AC light (when the AC is off) come on.
The blower turns off when the car turns off, so there's no problem with it running after I turn it off. The blower stays on 100% for as long as I drive, so it's not like it's stuck in automatic.
I took the CC unit out and made sure everything was plugged in snuggly, which it was.
I'm kind of at a loss. I suppose I could take out the fuse that controls the blower (if someone could steer me towards a fuse diagram that says what they all do I'd greatly appreciate it), but there's still a few months of cold left.
Any help diagnosing the problem is greatly appreciated.
Thanks!

Okay, I've finally gotten around to looking for a replacement (now that it's getting into the eighties daily). I just wanted to confirm that the fault is most likely in this:
And also, mine is a 96, but from my research I've found that the electronic units were the same from 93-97. Is that true?
Thanks!
