hello Cory, The Blower Relay have to be located in the Under Hood fuse block.Also, it usually job-related the other way around and also the just fan rate that functions would be the High. However, have you check out the Blower motor Resistor? that is situated under the passenger dash in the duct work near the blower motor..
So your saying over there is no seperate fuse protecting the hello blower? viewed that for years ~ above GM cars. How precisely do I inspect out the resistor? any chance the a pic? Thx Cory
