I've replace my blower motor, resistor and switch. I also checked my fuses and rotated my relays around to see if one might be bad but its still not working. When I replaced my old switch it had been burnt. I replaced a fuse also but no help. Any other ideas?

 

use a volt meter and see if you have 12 volts at the switch...on high, the 12 volts goes directly from the fuse panel through the switch and directly to the fan motor...the other speeds go to the fan motor via the resistor network...that is how it makes the motor run slower by adding resistance....but on high it goes directly to the motor...check with the volt meter, for 12 volts first at the fuse....than at the switch, than at the female connector at the fan. I had it there, but my motor still wouldn't run, it turned out to be the connector on the fan...so I cut off the connector, and wired the fan directly to the harness, and all my problems went away....hope this helps a little.

 

Thanks aa7kn! I checked the voltage at the connector and had 12v at the female side. Then I ran a wire directly from the battery to the male end just to check to see if the fan was working and it was. So if I put juice to the male end and it worked and the female end showed 12 volts, where would the problem be? I can remove the connector like you said and it would probably work, but why is it not working now?
