I have replaced the headlight wiring and the lighting control module (LCM) and when I turn on my high beams, my left high beam does not work.

there is a grey or tan connector right in the middle behind the grill but in front of the rediator if you remove the black plastic cover that goes on top of the core support (its the black plastic that is around hood latch and goes from one side to the other ) and you will see that there are two pins in there thats where the police had the wig wags plugged in and when they took the wig wags out they didnt put the plug back in but you can just wire the two wires together and both high beams will work i found this on my 2003 ford crown vic i had the same problem

is it possibly the bulb itself? some cars have seperat fusses for left and right head lights

I just looked under my hood and checked that wigwag circuit and it was absolutely truth they had just cut the wires I have been tracing this problem for a week thank you for whoever posted about that yes jumper the wires together man they we’re just cuts into all had to do was wire them together and everything went back to working kudos to the man at post this could have been a 125$ cost that took about 5 mins to correct
