Bad ground? Bad relay?
Read you owner's manual! to answer your question there is one fuse and one relay associated with the windshield wipers. The FUSE is in your passenger compartment fuse box. It is fuse #19, with a rating of 7.5 and it is Brown. This fuse is called Windshield wipers (circuit breaker). The RELAY associated with the windshield wiper is also in the main fuse box in the passenger compartment. It is R15, a GREEN Relay and it is the Windshield wiper motor relay. I hope this will be of use to you.
Under the cowl at the base of the windshield, on top of the wiper motor, three T20 Torx screws to remove.
Hey Maria==I don't think it has a relay. It should have a fuse and I thiink it has a circuit breaker in the motor. Check ALL of the fuses.Good luck Joe
The windshield wiper relay is located in the electrical power distribution center.
