Hi Gang:
I had just replaced the heater fan and fan resistor on my daughter's 01 Malibu. It did not function at all. When I pulled it apart, the fan was stuck pretty good. I did manage to work it loose. I did'nt consider reusing it so I purchase a new fan and resistor from Napa. Now when I turn on the heater
fan, I only get the first 4 speeds, not High!:banghead:
Any Ideas? I am going to check for fuses or relays next.

Thanks, NDAV8R

blower motor high speed fuse.. underhood junction block :-D i think it's 30A.. maybe 20A.. or 10/15... maybe 25 amp

Hey There:
As it turns out number 53 fuse (30 amp) was blown in the relay panel under the hood. Thanks for your Help!
