Duo Therm A/C unit

Ok, I am helping my neighbor get his 1994 Four Winds TT out and cleaned up, and we have it in his driveway and he is plugged in and wants to run the a/c. So he plugged it into his generator, and went to start the a/c, and the compressor ran, but the fan did not come on.
This is his first time having it out in over a year, so the motor is probably froze, and we want to try to find the motor to try to spin it.
Only problem is we are having trouble finding where the motor and fins are to do so.
Can anyone help with this?
This is a Duo Therm By Dometic with a seperate thermostate, no controls on the ceiling unit.

Pull the screws and remove the cover on the unit up on the roof. You'll see a squirrel cage fan. Give it a nudge.

It may be tight from lack of use, but low voltage will produce this problem as well. Been there; done that.

We did that, it was froze, so we spun it a little bit. Still wouldn't work, so he just un plugged the connection from the relay and plugged it back in, and it made it work, not sure what it did, but it works now.
Thanks for the info on trying to find the fan!

Dometic has had that problem for years and they never can seem to get it fixed. The solution is to run the fan motor about 15 minutes every 3 to 4 weeks.
