1998 GMC Sierra V8 Four Wheel Drive Automatic
Hello I am sending anouther request on my vehicle
I have only the high setting on the fan motor
I have replaced the air actuator the heater relay the
control pannel on dash and the heater blower resitor as requested by you guys,
up until I replaced the heater relay I couldnt controll the temp it was on high always.
what next? I am so frustrated with this now.
There are two wires going into the motor one is purple and the other is black test light works on the purple on high only tried it on lowest settring 1st
I see 2 yellow wires in a harness thas is connected to something on the fire wall but no others
after looking further I found the yellow wire going into the resistor and on low it has no power going to it
