I've got the typical Cruise Air / Dometic set up. Compressors in the engine room and evaporators / air handlers in the state rooms and salon.

In the guest state room the blower motor is bound up. I can turn it by finger tips and I'm trying to get PB blaster in there. It's in such tight spot that I can hardly get my head and the can of PB blaster in at same time. But it is getting looser.

The question is...Am I wasting my time? Has anyone really brought one of these back from the dead. I'm guessing the bearing just got a little rusty during a prolonged shut down. what do you guys think? Thx.
