So the hot/col knob works, the blend door works. but the blower only works when your on power level 3. 1, 2, and 4 it shuts off the blowers. Any ideas?
Blower control only working on 3

That's strange. I would say probably the blower motor resistor but when that goes bad it will only work on the highest speed. If it was a fuse none of the speeds would work.

This is what my resistor looked like when I replaced it. It's not much more than $10 and only takes a few min to switch out.

Are you still under warranty? Take it to the dealer.

Solved it! The fiancee reports she saw smoke coming from her dash once... Pulled the temp controls out.. The back side of the power control had some melted plastic that fused to disable the other power levels. Well I pried the temp controls open and cleaned up the contacts and scraped off the plastic and sure enough it worked.
What do you suppose caused the plastic to melt/burn in the first place? I'd be a little nervous it could happen again, and maybe with a worse outcome than just losing a couple fan speeds. "Where there's smoke there's fire."

Good question. I honestly don't know. If I had to guess..water may have made its way back there as one of the contacts looked worse off. If I wasn't looking for a cheap fix I would have bought all new temp controls for 130 from dealer.
Only other thing I can think of is that possibly a piece of plastic broke off of something and interfered with the contact points...there aren't any wires near where the affected parts are.
