yesterday I turned on my wipers when it was cold once i just turned on the car and well the passenger side wiper does not seem to work while the drivers side does. It jerks a little bit up and down bout half an inch but other than that it doesnt work, im wondering if something with the motor needs to be reattached or if i have to buy a new wiper motor all together, or if its a job that i leave to the guys at the shop. I was wondering how much this would all cost and how would i be able to install a motor if needed.
