Blower motor stopped working. Nothing on at any speed. There is power up to the relay (4 blade / prong mounted on the firewall), but no power at the blower motor itself. Safe to assume bad relay, or is there something else I should check? Any thoughts would be greatly appreciated. Thanks, ER

 

Run a jumper wire from battery + terminal to the blower motor terminal. That will tell if the motor is good.

The relay should only affect high speed.

 

I pulled the terminal from the blower motor and checked it with a test light. It appears there isn't any power going to the blower motor. Is my thinking correct?
