blower motor question
I've done a search on past posts but I'm still uncertain about the answer to my question. My blower fan starter whistling last night when I turn the fan on. I assume its the blower motor. My question is do I get this out from the engine side of the firewall, passenger side? I'd swear thats what my service manual said when I read it. But reading some of the past posts, I'm confused. Not sure if I need to get under the dash to get it out also. How difficult is this going to be? '72, 350, 4x4, fact ac. I get heat, not all that hot but I think I have a bad thermostat that needs replacing too. Any tips or things to avoid? Whats the proper way to do this? Is it absolutely necessary to remove hinge on pass side? Should I replace heater fan at the same time? If so, is that in same area as blower motor? Do I need to replace core? I think I'll open up the heater and duct work to see what goodies I find in there. Any help appreciated.

I think you need to remove the hood hing to put a new blower motor in if you have A/C not sure though.

You have to remove the fan from the engine side. Its easier if your remove the hood and hinge on that side. Unless your heater core is leaking or its not warming up, I wouldn't mess with it. Good luck, Jeff.

remove the hinge, blower cage and motor are connected and will come out togeather. my heater core took a crap a year ago and i went in and redid all that stuff, inside and out! (really, if can just remove the bolts from the hood hinge at the fender you should be able to get the hinge and hood to move out of the way enough to remove the motor, just gonna need a little help holding the hood up while you work on getting the motor out)

I did mine last night. Had to remove the hinge. I just propped the hood open with a broomstick and put a block of wood in the rear to support the hood. You'll need a 1/4 inch drive long extension and a universal joint for the socket.
I replaced my fan, the relay, and the resistor inside the airbox. Man, what a difference.

That bottom bolt on the blower cage is fun Most guys just break the cage, but it can be removed with out damage if you're lucky.
