I can't comment on the wiring portion of your issue but the squirrel part, maybe.
I assume your blower motor bearings are going out. If that is the case, you can lube the motor aft bearing pretty easily, can't recall if you can get to the front one off the top of my head.
I have used Marvel Mystery oil on my rear AC that did that. I got 3 years out of it before it started indicated it needs another shot. Another thin oil would surely work but would not recommend something really thin like WD 40
I used a syringe with a long tube on it to get the oil to weep into the motor shaft so there was not so much oil mess to worry about leaking into the roof or whatever. Access is gained by removal of the top outside Plastic (PVC) cover.
I also replaced a fan motor on another Penguin which was no fun at all but cheaper than replacement of the AC unit. Parts are available.
Not sure if that is your squirrel you mentioned or not...

Going to Tampa with no AC;(
