Hey all. I have a '95 Silverado 1500. For whatever reason the heater blower is not engaging. I've changed out the heater blower motor, blower motor resistor and just now changed the heater switch. Still nothing. I am at my wit's end with this thing. Now I'm here asking for your help. I would really, really appreciate any advice on this. Cold weather is right around the corner!

P.S. Yeah, I checked the fuses lol

 

Check the wiring for voltage from the fuse panel to the switch and from the switch to the resister and blower motor.
