my blower motor only works on low speed. Is there a way i can check if its the motor or the switch?... thanks

 

Welcome to TGO. If only the high speed is not functional, check the relay.

med or high speeds do not work blows at the same low speed no matter what ypu put it on

 

Like said, check the relay - it's under the hood on the blower box. Might also look at the resistor, it's on the box as well - little polygon looking piece that is held in with two 7mm screws.

Otherwise, might be the switch itself, but the first two are easier to check/replace. If you go into the panel to look at the switch, be careful not to pull any of the vacuum lines off the assembly - there's a slew of them back there to adjust vent doors and such, and the General didn't give us much (if any) slack to pull out the assembly.

 

great thanks for the info. ... Ill check the relay and the resistor
