So take it to the dealer if your in 3yr 60,000km

 

Similar problem' Dealer can't find cause

 

First is the obvious. Does it have a towing package? If so, check the trailer wiring plug under the bumper. If you hit something with that, you can bend/break something and short the backup light connector (this wire goes to the trailer so that if you have surge brakes on a boat trailer, for example, when you go in reverse there's a solenoid that disables the surge brakes as you would have a major problem backing up since that would activate the brake.) If that wire gets grounded, going into reverse will blow a fuse every time. Next check would be wiring in the rear to be sure the reverse backup lights don't have a problem nor the wiring to them. It is an almost sure bet there's a short in that circuit somewhere. You can always hunt it down with an ohmmeter. Disconnect the trailer connecter wiring harness and measure the backup-light to ground. Should be open. 0.0 says short in trailer connector. Move back up the wiring in the truck to the next point where you can disconnect the backup lights. When you reach a point where the circuit is open, you know the short is between where you tested last and the current point...
