The back door was not closed all the way and we had a bad rain storm where we live in California and water leaked in on the right rear back door. I pumped and vacuumed out, two to three gallons of water in the floorboard and ran a heater ventilator or fan and got everything dried out. but, now my turn signals, power windows, power mirrors , front heated seats, radio, GPS,dash lights and windshield wipers do not work. I checked all the fuses in the fuse box in the glove box and also the hi amp. fuses near the battery all were good. I am supposed to have a second fuse box in the rear right fender well, but I cannot find it. could you please tell me where the second fuse box is located or what could possibly be the problem? thanks a lot.

Hey WCS,

It looks like it is under the right side floor board, here is a wiring diagram of the fuse box.

Please let me know what happens so it will help others.

Best, Ken
