Heater Fan doesn't blow on low

you could hit the positive term on the blower motor with a direct battery wire and see how it spins before you pull it apart

In the process of replacing the blower motor as that’s what ended up being the sole issue. Have the old one out and the new one painted and prepped to go in. Looks like the motor was sealed at some point likely many years ago with light gray RTV that is brittle and cracking now.

What did the factory use? Would it have had a gasket, strip caulk, rtv or? I’ll need to smooth the blower motor box surface before I reinstall. Also the old motor has the squirrel cage, flat washer, star or windmill like washer and a square piece that I believe inserts into the back of the squirrel cage but not sure. How is it supposed to go on? When I pulled apart it all kinda jumped off then fell in the floor so I’m not sure what’s right.
