If you mean the windshield wiper blades keep falling off, it means the clips that hold them on have become too loose. Also, next time you replace them, you might want to switch to the kind that tighten with a screw instead of a clip.
Replace the windshield wipers.
It is under the cowl thing. You must remove the wipers. MAKE SURE YOU MARK THE LOCATION OF THE WIPERS ON THE WINDSHIELD.
IIRC its in the underhood fuse box
look it up
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.
First, make sure the windshield is clean and then take some alcohol and wipe the wiper blades. HTH.
i believe the 1999 - 2006 have a recall on the wiper motor. see your dealer.
If they don't work replace the fuse even if it looks good wipers will freeze to window and fuse will blow
You have to replace a relay switch for the wipers this sholud be found under the hood in the engine compartment fuse box.
I believe it s a 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.
It is under the black plastic trim plate under the windshield wipers.
