Hello

Welcome!

Did you check the relays should be up under the dash drivers side, Should have HVAC next to it.

Does this have breaker type fuses?

Thanks

Customer
have two fuse/relay boxes one on right side under panal and one under hood

Hello

If we have power threw the fuse and relay i would look to see if there is power to the blower motor resister, The power from the relay goes to the resister (located on the HVAC housing) then to the switch then to the fan motor.

Also check the wiring here to at the blower motor resister there prone to get hot and melt the resister end, The new resister come with a replacement end I use the shrink tube on my repair instead of the buttconectors they send with the kit.

Let me know if i can help more!
