Back up lights on driver's side were full of water. back up light indicator came on - light stopped working. we drained the driver's side rear light assembly. sprayed electrical contact cleaner in both 1156 bulb sockets and replaced both bulbs and are still getting trouble light on dash and back up lights are still not functioning. fuses are perfect.

replace the bulb, you can access the bulb when you open the hatch. there is a cover at the back of the tail lights. or go to your local autozone or pepboys. they will replace it for you with no extra charge

Testimonial: "A friend showed me how easy it was to access the bulb by twisting the holder and then removing bulb. YOur response was excellent as well. Thanks! "

Blown fuse. Do you have your owner's handbook? The fuse should be labeled. The location will be inside the car. Look under the dash on the driver's side and you may have to pull fuses to make sure they are good, but it should be only 1 fuse.

what about the courtesy lights fuse? or maybe your blinker switch? you might have a broken wire between the socket and the switch or the ground which would go to the chassis
