Ac/heater fan stopped
So the ac/heater fan in my 2004 blazer just decided that it would stop working today. I get nothing when I turn on the climate control. Its been very hot the last few weeks here, whats ironic is that my gfs chevy cavalier just did the same exact thing. Her fan randomly stopped working and then started again a few days later. I checked the fuses and they seem alright. I cant find a fan relay under the hood, just relays for the ac. The ac compressor seems to be working fine though. Some of the lights in my climate control panel have been out for awhile, could it possibly be the climate control panel? Is there any chance that it will start working again? Im pretty sure that the fan is not burned out. When I turn on the climate control I can here whisps of the air moving, I can feel the warmth or the cold coming through. The fan is simply not blowing it. Please help.

So I went through and did some diagnosis. Im getting power at the motor, my relays and resistors and fuses seem to be ok. I then whacked the blower motor housing and she began blowing air. Is it safe for me to assume that I need a new blower motor?

if nothing is blocking it from turning i would say yes.

Had a similar blower moter problem in my 94 S10 Blazer. The fan switch had overheated and melted insulation at wiring connector. fixed that and still had an intermitten problem that turned out to be a loose connection at the wiring connector between the fan relay and the fan motor. All is well now. My relay is mounted on firewall under hood.
