The windshield wiper relay switch, on your 1999 Cadillac Deville, are located mounted to the firewall in the engine compartment. The relay switch will be next to the windshield wiper motor.
If the windshield wipers work when pushing the lever down but not when they are turned on all the time, the problem could be in the wiper motor relay switch. There are two different relay switches for the windshield wipers, so that if the one fails a person can still clear the windshield manually.
You have to replace a relay switch for the wipers this sholud be found under the hood in the engine compartment fuse box.
You either have a bad relay, wiper motor, or bad switch.
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
