The blower motor is making noise (91 silverado k1500) and I'd like to replace it. I've got the Haynes manual but it does not do a good job of explaining the procedure.

Does anyone have good diagrams and/or a better-written procedure?

 

It's pretty straight forward just get in there with your 9/32" socket and start removing whats in the way on the passenger side behind the glove box.

 

What kind of noise might be something stuck in it .
Maybe a leaf, ect. This time of year mine always gets a leaf or too .

 

Squeals when it's cold. Goes away after it warms up a minute or two.

 

I would not worry about it for now. Mine does same thing for years , i have a 91 silverado. Heck mine gets water in the heater box , condesation from where i use ac a lot.
Had too drill a little hole, let water out. My motto wait till it goes out , then fix.
There is nothing to change it out like Shamrock said , take it apart , watch how you take it out , put it back.

 

Really? That's exactly what mine does too!

I just realized - if water condensation gets into the motor bearing this may be the cause of the squealing.
