my fan is not working and we just keep getting snow piled up over here. Where is the fan located or how can i fix it. It started with low med High then low high then high only but now nothing. Help please.

 

the sensor thats a coil next to your fan is bad let me get the name for u heater blower control switch basically its a resistor

 

the blower motor is on the passenger's side, bolted to the firewall. there are a couple of tricky bolts to get at down there, but with 3/8" elbow you might be okay.

 

Sounds like the blower motor relay. Located on the passenger side. Inside the blower assy. Kinda have to lay on your head to get to it. It will have a green looking circuit board and you should see alot of burning and flaking on it. Had the same issue on my Venture and a Impala.

 

Blower motor is not that hard to replace. I've had to put 2 of them in my 92 S10 that has 160,00.
