Troubleshooting Left Tail Light on Vehicle Not Working Properly After Harness Installation


I have a 2015 Chrysler Town and Country. I ordered your harness and installed it exactly per the youtube installation videos. Since installation the left blinker of the van has acted weird. The trailer lights work perfectly, incidentally. I finally got the chance to take a look, and what is happening is the rear taillight assembly now blinks both the reverse and blinker bulbs when the left blinker is on. They are both dim, which tells me they are sharing the voltage intended only for the blinker bulb. The reverse light does not light when we put the van in reverse, although the right one does.

It definitely sounds like there is some connectivity between the two functions that should not be there. I recommend cleaning your terminals and using dielectric grease # 11755 to help the electrical connection of the correct function while mitigating the sharing of function due to moisture, dirt or debris.

You can ensure it is simply a function issue by just disconnecting the harness and using a small jump wire to test each function.
