Default Re: No power behind air blowing out of vents

We need these to make blower work:
Voltage
intact wiring
functional switch
the resistor thingy in the plenum
and a good blower motor.

Simplest is to get a cheapie voltmeter from Sears.
Test at blower first, it's likely the EZest to get at. Yes, you'll be in an
awkward position.

Ask one of the guys to get you a FSM (Factory Service Manual) in pdf
format. It'll tell you the procedure for your model and year, and access to
these components.

Here's an '01 blower, most vehicles are similar, Some GM's put the blower in the engine bay.

Passenger's footwell:


Carpet removed, velcro and 'nippers' or fingernails, screwdriver, whatever to pull the little pins:


Please excuse the shakes, 10 second exposure. Location of four 5/16 or 8mm screws. Use a Craftsman/Snap-on 1/4" ratchet and 8mm or 5/16 socket.
You may have to finagle the hamster cage out, pull back carpet a bit.
The connector has a red lock you have to pull or push to get the simple latch to work.
They only put these 'locks' where:
1. it's absolutely needless
2. Impossible to get at.
3. The connector get old and brittle and breaks trying to undo lock (Fuel injectors).
Dunno why I wrote 'Red' in the screw box. Ignore.


Blower removed.


Box- Reach hand into hole, you can feel the fins and debris. BIG snakes live in these boxes ...
I was only bit once this time.


Debris.


Cost:
Ratchet, socket, snake bite kit.

Takes less than 1 hour.
