Fan speed
#1
The AC/heat fan speed works on lowest setting, then it stops working when placed in the next highest position (low to middle), and works again in the higher postions 3,4,5 highest. I checked all the fuses and they are good. Any techs no about this?

Thanks for the link to parts, the picture will help me find this thing. Looking under hood, I do not see anything mounted on firewall. Sure wish I had a picture of this vent motor location / access.

Thanks, that is an excellant resource. I actually found some schematics for the AC system. Looks like either a bad switch, or open resistor problem from the drawing anyway. I pulled the **** off of the Fan speed selector switch, and notice some resistors in there on a small ciruit board. Wondering if those are the ones?
