Anyone ever had trouble with ac blower not running on high? My 1980 Firebird has a new blower motor, fan switch and high speed relay. Works well on every speed but high! Resister tests ok. Any advise appreciated! Kurt
reach behind pass side cylinder head there is a harness connector cut thick red wire and by pass connector join red wire together where it goes to relay by evaporator
Thanks guys. I finally discovered a dead negative lead (I think it was to the high speed relay). Rerouted it to the negative bolt on the firewall and all seems ok. I really appreciate the advise! Kurt
