The wiper on the driver's side is not working. the one on the passenger side does. I thought it would be the motor but shouldn't be since one side is working. Any ideas?

 

The motor is on the passengers side. There is an link connecting the motor to the passengers side arm to power it. Then a link connecting the passengers arm to the drivers arm to power this. This link may have problems. Typically the link connection to the arm fails.

You will need to remove the wiper arms, lovers and weather strip to access the links.

 

Hopefully it is not too expensive to repair and that we can do it ourselves!
