2002 Chev Tahoe rear blower not working. How do I fix?
I have separate controls for a rear climate control system, however the fan Speed Knob gets no response from the blower. Fuses all seem to be in-tact. Is there possibly an override switch or control of which I am not aware? Thanks in advance.
There are only three things that can happen to an electrical circuit: an open, a short, or a ground.
If the motor runs OK wired directly then check for a loose ground or no ground, check for a broken or loose wire from the fuse to the motor (you could have an open in the switch as well by the switch not closing completely) or a short in the motor if it doesn't operate normally when wired direct. Here I am speaking of the field wires shorting eliminating a portion of the coils. Look for screws that have gone through the wire bundle or where the wire has chaffed against metal.
If you aren't burning the fuse I would look mainly at a broken wire or bad switch or no ground.
