passenger wiper arm not moving

The right wiper arm is not moving when the left does. Something is slipping. I say this because the left arm moves as normal but the right only moves if I help it. If I stop helping it along, it will stop moving again once it reaches the rest position. Experience, ideas, comments?

sounds like arms off wiper motor or wiper is stripped.good luck.

After finding the time to actually LOOK at everything, I got off easy (and cheap!). The nut holding the right side arm on the shaft had somehow come loose in a VERY short time span. Good to go now.

Just check it out and if you are not able to solve this problem, get it solved by mechanic.

thats the mechanical fault in your motor, and my advice is that instead of repairing it buy a new one and cost will be almost the same.

He already fixed this problem 3-years ago, it was a loose nut!

If one wiper works, tells me the wiper motor is good.
