I had replaced a bad blower motor last summer when it quit working on low then finally high as well. Also replaced the board that controls the high to low settings behind the motor. It has been fine until last week when the motor quit working on low again , and now it emits a bad electrical burnt smell when running on high. I just uncovered the blower motor which seems fine but does seem not seem to be turning as freely as I think it should , I'll also check the resistor board behind the blower as well. Any tips appreciated thanks 93 previa 290,000.... 6 months on JPM motor and all is well.
