Ran power directly to blower motor and motor runs. Replaced resistor, relay and A/C control module yet blower motor still not blowing. When I bypass the ground coming from the blower motor and press on the fuse panel on the passenger side the blower motor runs on high. Any help with this would be greatly appreciated.

 

Did you check fuses?

Interior fuse block
#10, #16, relay #30

Underhood fuse block
#22 (air conditioning, probably not the cause)

 

Yes. All fuses are good.

 

I’m thinking a bad ground wire, if you bypassed the ground then pressed on the fuse block possibly the under hood fuse box halves might be loose.

He pressed on the interior fuse block.

Rick, is the Check Engine Light illuminated?

 

But there could be problems pertaining to fuse #22.

the wire harness connector might be at fault the wires into the console fuse box might be loose.

 

Are you sure it was the ground wire? It is not wired the way most people assume.

The hot wire is always hot.

If it runs on high only that means the resistors are not working, they are on the ground side.

 

Check engine light is not on.
