Lighting issue

[Russmccardle]

My 04 2500 diesel is having a problem. Left turn and brake light out. High beams only work on left side and lows on right only. No turn signals in front. All running light work and light work at the 4 pin trailer connector but not the seven. Any ideas?

It is more than likely a problem with the front control module

I just pulled the fuse box out. Noticed a little green corrosion near a weep hole. The lighting control module was my next idea

Well I swapped the front control module from my 03 into my 04 hoping the lights would work. Still having the same issue. Wanted to use the fuse box in my little experiment also but a couple connections were different. Starting to think it's the fuse box itself

You can take apart your fusebox and clean it. If the corrosion is bad enough, you may have to solder a jumper wire into complete the circuit.
