Passenger side brakelight/turn signal

88 4.2 auto trans

Hey guys, i recently installed a new driver's side tail light, housing and all. The bracket was rusted and the lights were just hanging inside the plastic cover. Replaced with a oem style light, not led.

After the swap i noticed my PASSENGER side tail light was being screwy. With headlights on, the brake light and turn signal werent working. I just went out and fiddled with a few things. Pushed the wire harness under steering column together real good (didnt feel loose) swapped the lights from the driver to passenger side and now its working fine.

My question is, will the problem come back? The harness that i messed with wasn't loose at all. I did replace my battery 2 days ago because it tested bad, and this is the first time i checked on it since then. Did this fix the problem and i just now noticed? My windshield wipers are working sporadically as well, sometimes they freeze up, then they will start working again. Maybe unrelated, but i thought i'd add that bit of info.

Anyway, hopefully the problem with the lights is gone, but any info would help.

Double check the ground for your tail lights (the mounting bolts to the tub) bad ground will do some goofy stuff.


Smoke em if you got em!

Sounds like a case of bum connections and grounds. X2 on the tail light housings, they ground thru the tub. Even if the connections feel tight, I would take the time to make em shiny and put all back together. The windshield wiper motor has its own plug-n-harness behind the dash pad - check-n-clean that connector, and anything where metal bolts to metal back there around the motor. Its a high-rust area since water tends to get in around the windshield gasket.

I would check your battery ground cable, that is the ground for the lights and ww motor. since you said you changed batteries always check what you touched last, the battery connections

You might want to try working the 4 ways a few times see if your problem disappears. If not time to replace the turn signal switch.

A 89 yj with a 4.0 aw4 sye out of an 92xj. Now the hard part is done time to get it up in the air just a bit. Working on 8.8 with 3.73 and lsd for the rear. and new D30 hp with 3.73 .
For those who have not figured this out I'm old school but can handle the new too.
