Are there any common problems with the heater controls? For example, my fan speed control is totally off. It's like the internal contacts have moved by 1/8 inch or something. I can't get the highest speed. And the contacts don't line up when the switch "clicks" into place. I have to put the switch in between the speed selections. Anything special I need to know? Do I just need to pull the unit out and adjust the small box that contains the contacts?

Please don't make me bump it again!!!

 

What year is your Toyota? If its old stuff its probably a bent switch lever and it would be easy to fix with a little patience. Just be careful not to break the face of lighted control background.

Itf its new stuff, I dunno.

 

It's a 91 V6 manual. 150K miles.
