I had a bad relay on my F250 that caused me to change the blower. Had 12V to the blower but it would not turn. After FINALLY checking the relay I noticed a burned spot on the side. Changed it out and I had air.

Shows the blower motor relay. Only applies power when the high speed is selected.



Fuse box and related wiring for the blower motor fuse.



Rest of the wiring for the system.

You should be able to find the relay in or around the fuse panel. Check first if you're getting voltage to the fan, maybe a bad fan?
