Blower motor replacement - The 1947 - Present Chevrolet & GMC Truck Message Board Network

It looks to me like the hood hinge has to come off to replace the blower motor (72 K5 w factory AC). Anyone know for sure?

not necessary, but makes it a lot easier (from what I have read)...

See if this helps (it is for a non-A/C though)

I just take the hinge off, with or without a/c. Its quicker, and easier.

ARe you sure the motor is bad? Many of the A/C trucks loose one or two of the speeds due to faulty grounds or bad relay over the heater box behind the glove box. I think 9 of 10 trucks I have parted out have had mice nests or mice damage to the little barrel fan on the motor~~~. Huck

The motor works. I'm just tired of the squealing bearings.

I just pulled mine. It was really easy. I marked the hinge with chalk to make sure I could line it back up. I propped up that side with a broom stick and took off the hinge. You may have to pry the fan motor off. The whole job took like 20 minutes and I did it by myself.

Hope that helps

Thanks. I might get around to it this weekend.
