Why doesn't my 2001 Chevy blazer heater blow on high?
The high speed of the blower is controlled by a black rectangular relay on the firewall facing the engine compartment on the passenger side (I think there are 3 relays there) one is for the high speed. If you open it and the plastic base looks melted > it's most likely the relay I believe the ralay is under-rated bacause if you use high speed alot (like I do) it burns out prematurely.
