Hello XXXXXX, What relay did you replace? Have you checked all of the fuses under all fuse covers under the rear seat? Can you check the relay module under the seat? Let me now what you find. Thanks

Answer

Paul, sorry for the delay. the relay module is the larger one that is about 8 inches long and should have letters RM. Just to make sure that we are looking under the rear seat.

Answer

Sorry it is the wiper washer relay that is under the hood. the wiper relay is in the rear fuse box. It should be the one closest to the left rear door. Let me know if you have trouble I can send you a diagram
