Hey guys, when I bought this Cherokee a couple weeks the turn signals works fine.

now this is happening...

Headlights off:
right turn signal functions correctly
left turn signal functions, but when blinking, all internal lights flash with it. Ex. Gauge cluster, stereo, shifter bezel light..

Headlights on:
right then signal functions correctly
left turn signal dash indicator stays on, whether the turn signal is on or not and in the front of the Jeep, on the driver side, one of the two bulbs in the flasher would be fully light up.
when I turn left signal on, all flashers flash on the left, except the super bright bulb in the front, but no interior lights flash with it like when lights are off.

the solution I have found to fix this:
while replacing all the bulbs thinking maybe the bulbs were bad, I found that the bulb that is super bright when the lights are on... if I pull that bulb and leave it out, everything functions as it should lights on or off. Put the bulb back in, issues come back.

what is the culprit and how do i fix it?

 

Take the bulbs out and clean the sockets. Front and rear.
