So I've connected all wires check fuse no power to fan. I did put direct power to fan and it work! What am I missing? I check the power at the firewall have power at horn relay how every I only have power on one wire looks to be brown from blower motor relay?

 

Ok found it! Two wires connected at the bottom. The brass connector was completely gone. MDchanic you rock thanks

 

You're welcome.

Sorry I didn't see your earlier posts - I was driving 350 miles.

Glad you got it fixed!
