LED Tail light problem

I just bought a 98 TJ, the PO installed LED tail lights. The right rear blinker is not working, the left rear works but turns off when the breaks are pressed. The dash and front directionals work however they blink fast like when a bulb is out.

I am new to the jeep world, any help or advice on where to begin tracking down the cause of this issue will be greatly appreciated.

Thanks

It's most likely a ground issue. If the bolts that hold the light housing to the body are corroded and won't tighten it's not getting ground. If you want to check hook a jumper wire to the bracket inside the housing that holds the bulb and clean a spot on the frame to clamp it to. I actually have one installed permanently for the same issue.

It looks like the PO grounded the lights right to the body.

I assume the ground needs to be to an unpainted surface?

I checked the grounds today, all were fine.

Think it could be the multifunction switch??

I had issues like you first described and they were all due to poor ground. After I jumped the ground to the frame everything worked fine for me. I don't think the switch would cause these problems but I'm not an electrical whiz. Lol

100% ground issue. I had this problem until I added a ground wire to both lights.

I picked up a new multifunction switch today and popped it in, signal lights work no problem now. I also thought it was a ground issue for sure...

Thanks for the help.
