Truck is afraid of the dark......

Any changes to the system from the stock lights?

Unplug the headlight switch and see if it happens again. Possibly a bad....new....switch.

It is sending signals to a another ship in the distance. It's lonely. Get another truck!!

Sorry... Too much coffee....


Check the back of the fuse box and check the GEM for signs of dried up water.. Corrosion etc.
These trucks are known for leaking windshields at the top drivers corner. The water runs down the A pillar and into the back side of the fuse box and on to the GEM. The GEM is what controls the accessories. There have been other wierd things happen when that gets wet... Truck dies when using the wipers, Radio comes on and off on its own etc.

And dont ever believe that anything new is working fine unless you have tested or proven that it is good. I have seen many switches DOA out of the box. Although the same exact issue with a new switch is unlikely, but not impossible.

Can you tell if it's your high beams or low beams that are coming on. It could be your multi function switch or a chafed wire in the column.

Ok. So now the parking lights come on and stay on unless you unplug the batteries. I disconnected the head light switch to see if that would do it and even with it unhooked they are still on. I'm lost!

I still think the GEM module is having issues. Have you tried just unplugging that? Or checking for water marks?

Yep....sounds like a water leak issue or GEM issue for sure.

Agreed, start with the GEM. Has it been parked outside or driven in a lot of rain lately? Leaks from the windshield seal seem to make their way directly to the GEM.

Gonna throw my hat in the ring for bad switches out of the box. Had a bad one show up for my wife's Jeep. Entirely possible. I don't think it's your problem, but yeah that's not unbelievable in general.

Don't want to high-jack but what is the solution for a leak at the windshield. New window/reseal?....

Most reputable shops can pull, clean and reseal the windshield correctly. Just have them give a little more attention to the top corners...especially the drivers side. That is usually where it has problems. Water collects in that spot then rusts and starts draining into the cab.

About 3 windshields ago, the guy installing it saw the bad spot and did some repair to it. Cleaned the rust, JB Weld to close any pin holes, primered the bare metal and kept it all below trim line so when the windshield was put in, you couldn't see the repair. Just be sure that if you do have this done... If the guy seems unsure at all, don't let him do it. I have seen good windshields destroyed by someone not being careful taking it out.

Thanks, I'll have to take a look in there my radio randomly tires to load a CD when there hasn't been one in there in 2 years. Happens with the radio on or off, then switches back to FM.
