I have 3 duallys and my son has 1... . we've had problems with the clearance lights on the dually fender... pulling this apart we find that the electrical connection between the bulb and the plastic housing is bad and its caused the housing to melt... . they are 26 bucks each from the dealer.....
We only have the 05 left under warranty... the others are over on mileage... 01, 04 and 04. 5..... as we fix these trucks we are putting some dielectric (sp) grease on the connection to see if we can make it last longer... .
The pins on the light bulb and the connector are different metals and with the chemical on the roads here... . they are going away... .
Check them now... and put the grease into them so that you have a good sealed connection...
