91 ZJ Brake lights, running lights, etc...

Girlfriendzilla's Jeep is acting up. I 'volunteered' to fix it for her.
Looking for some pointers on where to start my search.

I'm guessing it's a ground issue but here goes...

Lights off: Step on the brake pedal and the ambers go on up front along
with the brake lights in the rear.

Lights on: Left side rear is much dimmer than the right. Step on the
brake pedal and the brake lights are barely brighter than the tail
lights. If you blink, you miss it. Again, the left noticeably dimmer
than the right.

I've replaced a bulb or two in the past few years. None recently though,
so I don't think it's a wrong bulb issue.

Ideas?

Look to the dim bulb being a short between the signals and running lights.

I'll look at that.
I didn't even try the signals to see what they did or didn't did...
Hazards either.
Thanks!

Hi Clay,
With a bulb out and it's filament crossed it can do some weird things,
but not light the front, your problem I believe a melted turn signal switch
in her column, usually caused by a short in the trailer socket. find the
short first or buy more than one switch, as I have. It will come apart very
much like this GM: http://www.chevyasylum.com/column/tiltcol.html ,

battery, especially if equipped with air bags.

Maybe not a wrong bulb, but a bad bulb in one of the tail lights. I've
seen 'em where one end of one of the filiments breaks and lays down
over the other filiment. Causes something like you describe.

Bill, if the brake light filament breaks and falls across the running
light filament's base, which does happen, it then lights up the running
lights as well as the brake lights when the pedal is pushed while
showing the dimmest at the break point.

Both scenarios are possible.

iirc, the front running light thing has been that way for a while.

Recently though, she was rear ended by a light pole in a parking lot
(it's her story, and I'm not arguing...) that put a nice 'V' in the
bumper. Might have pinched the U-Haul installed trailer wiring.
I pulled the bumper and hammered it out so the back would open and
didn't notice any bad wires... but I didn't look for them either.

We'll check the bulbs, wires, and turn signal switch.
Thanks for all the tips!
