AC blower speed

[trctrdrv]

my ac only blows on high speed, is there a seperate fuse, or relay for the lower speeds or could it be the switch

Well I know its not the switch, I tried 1 that I knew worked, still only blows at high speed, nobody else here has ran into this problem

on your heater case beside the blower motor there is a (RED?) connector with 4-5 wires. It is the blower resistor pack, the thermal fuse usually pops. They are the same back to the '80's, so grab a couple from the local boneyard

thanks for the reply figured it out from someone else pulled the 1 from my old truck works great now but thank you for your help, glad it was something simple
