2nd Gen Non-Engine/Transmission Clearance lights

[DeereFan]

2 of the 4 clearance lights on my dually fenders are out. ( 1 on each side) I have swapped the bulbs and they are still good, I'm positive that it is a ground problem, but I can't exactly find where they are supposed to be grounded . Thanks for any help.

still 1/2 in the dark

Without taking the plastic out of the fenders ,it appears that the wires come out of the fenders in a wire loom that connects with the license plate light and possibly the tail gate lights. they all work, why only half of the fender lights.

you will have to chase the wires out. I had a coroded plug on mine a while bach that shorted the taillight out. Drivers side tail light under the bed there is a big clump of wires where a bunch of stuff is tied together check there and maybe switch the bases for new one on the fender lights.
