Hey I have a 1996 chevy blazer, My blower motor only blows on 1,2,3 and when I put it on 4 it stops. I've heard it could be the blower motor relay. If so where is the blower motor relay located? There are 3 relays by the blower motor in the left rear of the engine compartment, if its one of them, which one would it be? I'm new to the forums.

Thank you,
Jeremy

 

i believe it is located on the blower motor housing, mine is 99 like that.

 

I believe that is the resistor located on the blower motor, there's 3 relays above that housing, I just don't know which one is the blower motor relay and how to replace it.

 

Follow the wire from the blower motor (most are purple) and it should take you right to it. Yes it's probably your relay. Would need to look at a wiring diagram to be sure though. Don't have one for a 96. The blower on Hi runs directly from your junction block through the relay.
