My blower motor for my A/C & Heat will only work on high speed #4. The other speeds #1,2,3 will not work at all. I was wondering if anyone knew how to fix this?
Thanks for any help.
DR.

 

Either the switch itself has failed, or the resistor pack that takes the power from the switch and then runs the fan is bad. Either one, you are gonna have to have some electrical knowledge, a meter to read the various voltages, and a good Technical Manual to guide you through the process of first discovering which part is bad, then guiding you through the repair process ......
