'94 G20 AC/Heater fan only runs on 4/high will not run on 1/low 2/mid or 3/mid-high. Is it the fan motor or switch or something else. Thanks for any help you can give.

DAH! just read Readingsaint's post with the same prob. must be the resistor. Is the resistor located at the fan motor? :screwy: Thanks again.

The blower motor resistor is over on the passenger side in the foot well under the glove box. Look in one of the other thread about replacing it. It's a VERY common problem on the P10 G20s.
