Electrical problem
1999 Cadillac Deville V8 Front Wheel Drive Automatic 135000 miles

Is there a wiper motor relay on a 99 Cadillac Deville? I have replaced the motor and the circuit board and it still will not work. I have also replaced the fuse under the hood.

Do you
have the same problem?

Hello there,

Here is the location and the wiper wiring diagrams so you can do some testing.

there is also a rain sensing unit that could be causing the trouble as well.

Here is a guide to help test the relay which is under the passengers seat.

Please let me know if you need anything else to get the problem fixed.

Best, Ken
