Hi Guys, I've got a Chevy S10 pickup with a blower motor problem the usall fan only works on high speed ... Replaced blower motor resistor but still have same prolem (only works on high speed) the motor seems to be OK could it be the fan switch?
Replaced blower motor resister and still have same problem on 92 Chevy S10 2dr, 2wheel drive, small V6 ...
High speed doesn't use a resistor. Have to check voltage circuits to and from relay. At the moment, I can't rule out blower motor? It very well may run on higher voltage, but, not lower?
Check your fuses. I believe there's 2 for the blower motor. One for high speed only then a second fuse for the other 3 speeds. HTH. -Jim
