Any suggestions on how to test/fix?

The fan in the cabin just suddently stopped working. No AC. No blowing. No heat. No funny smells. No error lights. The display still lights up showing variable speed, but nothing is spinning. I checked the driver footwell fuses and the fuse under the subwoofer and they are all fine.

Does anyone know if the basic durametric will tell me anything? Perhaps the relay is dead? I don't think a relay is too expensive, but I'd rather not blindly replace parts. Has anyone come across this problem?

Thanks in advance!

 

It could be a relay problem. I had my engine compartment blower fan fail and it was a relay problem. Hope this helps.
