1. Remove the shroud on the A/C unit. 2. Try to spin the fan. If it won't or is very hard to turn; bearings are locked - new motor. If it spins free and easy, You need to see if there is voltage at the motor. If it turns with some resistance; the bearings have gotten dry and a drop if oil will help. RV A/C units use fan motors have oil impregnated bronze bearings that tend to get stiff when used infrequently and are of motor type that has low starting torque.
Same advice from me. I bought an RV that had sat for at least 2 years, and it had the same problem. Once I got the fan loosened up and oiled, it worked fine ever after.
