Lighting system malfunction
Hello Everyone,
I'm TJ from Toronto Canada. I am new to this forum. I have a 3rd gen Expedition Max Limited, 2010 to be exact. Last week, it started having issues with the entire lighting system. While driving, the entire lighting system including my dashboard and all other instrument panel lights, will randomly flash and turn off. Then turn back on and off again. They flash rapidly and other times, they turn off for a few min, then on for a few min. This also happens when its just the DRL as well. When this happens when its the DRL's, when I hit 20 km/h, the automatic locks try to lock the doors.(although they are already locked because the truck was never put in park or turned off). Today, when I went to take it to the 2nd mechanic shop, the gear shift was locked in park. The lights flashed on and off, but I could not get the shifter to go into Drive. It eventually went, so I could get it to the shop. As of 1 hr ago, the shop called and said they couldn't figure out what was wrong because it didn't happen for them while they had it. Besides the fact I am taking to a new shop tomorrow, I was hoping someone here might have had the same or similar issue so I can steer them in the right direction. Any help will be very much appreciated.
Thank You,
TJ

The only thing common to all those circuits that I see is a heavy red wire attached to the battery +, going down and hitting a 10 gauge fusible link, and then it keeps going into the cab to the smart junction box, which is the interor fuse box that has electronics built into it also. I would check the wiring out at the battery, leave the running lights on while you are fiddling with the wiring out there and see if they suddenly turn off.
