The factory incandescent turn signals on the Jeep Grand Cherokee illuminate in a slow glow, taking a moment to turn off and on. With replacement LED bulbs, you can immediately update your vehicle with the instant on-off blinking of modern LEDs. This instant activation adds a modern and distinct look to the Grand Cherokee.
I have the factory tow package on my 2015 Grand Cherokee. I have trailer brake and turn signals working but no running lights. I checked the rear 4 pole connection on the Jeep with a multi meter and get proper voltage from brake and turn signals but 0.04 volts from running lights. I put a new 20 amp fuse in the under hood fuse box trailer tow

I know this usually means the light is going out, however after a day or so the lights will come back on and work. This has repeated for about a month.
At first, everything seemed to work fine, the turn signals worked and the hazards worked etc. But, then I went to turn right and my right signal stuck on and would not turn off. Previously, I was able to get the right signal to shut off by flipping the left signal on quickly or turning on the hazards momentarily. 1) Remove the light assembly as if you were going to change a bulb. 2) Turn the socket and remove it from the taillight assembly and set it aside (check to be sure your bulb is not burnt out). 3) Look at the opening, you will see 3 flat chrome colored contacts on the assembly. 4) Notice the one by it self at the top of the opening, that is the 90 posts · Joined 2022. #2 · Nov 18, 2023. The flasher module doesn't have a PCI (CAN) bus, so the Body Control Module must monitor the turn signal switch status. After a cursory look at the BCM though, I see it monitors the Hazzard switch but not turn signal left-right grounds. Must be missing something.
