I had my blower motor seem to quit working. So i got a new blower motor, but never installed it. I tried to power it from a 12v battery and it spun, sound free. So i checked the resister, and it was burnt up. So i bought a new one. I also got a new switch and installed it. nothing. I plugged in the new blower motor, noting. I checked every fuse and even the relay. Everything seemed to work. What am i missing or what could the problem be? If you can help, i wud appreciate it. Thanks.

 

Maybe its the relay?

 

if you can figure it out, let me know. i'm in the same situation

 

ok took it into the dealership.
Some how, the relay went out, fried the switch and the ground by the air bag was bad. The blower motor was still fine. 87000 miles.
