Just saw a nice tutorial on replacing the blower motor with pictures on Pelican. Looks to be a straightforward repair assuming the lower bolts are not rusted out and sheared off. My working assumption is that this is a blower motor issue but that's just an assumption.
One electrical question though on testing if this is the source of my blown fuse. Can I attach any 12v source, like a trickle charger, on the electrical leads on the side (assuming only two terminals) to see if the blower works or if my source of overload is elsewhere? Access seems to be pretty easy and I'm thinking this could eliminate one source (or identify one that I can handle fixing). No blower action would show that it's locked and lots of noise etc would show bearings. if the blower works, then I'd need to look elsewhere.
Is this a reasonable approach? Or would it be easier to disconnect the power to the blower and see if the fuse blows to 6 when the car is on?
