72 350sl windshield wiper repair
 

I recently turned on my wipers, only to see the right one (from the inside) go over and the left not move. I shut them off immediately and have not tried since. Are they cable driven and where do I begin to troubleshoot and repair them. Any advice would be appreciated.

try removing the wiper arm and tighting the retaining nut...

thanks
 

DUHHHH!!! I obviously hadn't looked at it before posting my question but thanks for directing me to the simple solution.
