94 Tahoe blower motor

Wcbond · Jun 16, 2019

Ive got a 94 Tahoe with a blower motor issue.

I’ve got power on the purple wire on the blower motor when the switch is set to on. Got a good ground on the black wire on blower motor. All three relays click when switched on. Have replaced the resistor in desperation.

Does this sound like the blower motor has gone out? Any other connections to check?

what are you getting across the motor itself for powah
also gove us an ohm reading across the motor
but yes the motor could be shot. they will either start squeeling, wont spin as fast as it should possibly also blowing a fuse or jump past those and just die.

i found a dead mouse family that had died ontop of my blower box at some point on my 94 suburban i used to have. mine hadnt quit working yet but the bearings were shot and it was making a hell of a racket.

Mine was squeeling for years. I drilled a tiny hole through the plastic housing on the passenger side, and sprayed WD-40 where I believe the top of the electric motor is. The squeeling quit and ran quiet. I just give it a little shot every winter, and put a piece of black tape over the hole. Hillbilly maintenance I guess
