I don't know where to start (electrical)

1990 YJ, 4 banger.

Okay, here goes....When I bought this jeep it had no stop lights and no turn signals. The stop light switch plug was hanging loose under the dash.

I fixed the turn signals by installing the correct bulbs.

I plugged in the plug to the stop light switch. Walla!!! Stop lights, but...the turn signals have gone nuts. When I turn on the left blinker I get nothing in back but the left front blinks. When I turn on the right blinker Both lights flash in back but in front only the left blinker flashes bright and the right one flashes dim. Where would you start? Thanks, ahead of time.

Sounds like you are getting a power cross over somewhere that is causing it to short out.

I would first check where the wires go down thru the drivers side rear fender well in the back and make sure that they aren't bare or rubbed. Then on to the plug ins that are in the back of the drivers side wheel well.

After that I would work on either front or rear at a time, take both rear bulbs out and see if you have just front signals, then vice versa. they will flash fast but should only flash the bulb you are trying to light. If you can get 1 set (front or rear) to work, you will know that the problem is in the other set of lights.

I will do just what you suggested. I was getting a headache trying to figure this one out. Thanks for the reply.

Replace your turn signal switch. It's $20.

Why might it be the turn signal switch? The turn signals work perfectly until I plug in the stoplight switch. I don't understand.

Follow forlife's recommendation then tell us how far you get. The turn signal switch in the steering column if that is what he is talking about is a PITA to replace however it could be as simple as the flasher relay in the fuse box by the Clutch could be a loose connection in that relay and it is a 8$ part I just replaced mine.

Please remember it is a good idea to disconnect the ground at the battery so you do not short any fuses or relays while messing with these parts some people are creating more work for themselves by not doing that.

Just my .02 cents

Thanks, Chief. All ideas are welcomed. As soon as the ice melts today. I'll get on it.

you know I had this exact same thing happen to me and it drove me insane because redone all the wiring and made sure it was correct with my tester but as soon as it was hooked up it went haywire turned out that one of the bulbs were bad, it had a piece of filament touch both the turn signal and the tail light filaments causing it to short out and sorts of crazy things

mine was doing some freaky blinking when I got it . My solution was I pulled every bulb and started checking them one at a time. when I got to the front blinkers, I put the bulb back into one and it went crazy again. turns out the po had put the wrong bulb in there and it was contacting both sides of the connector. I changed both front bulbs and it fixed my problems.

Right next to the fuse box there's a black rectangler box with four flat prongs in a row and two flat prongs in another row. When I plug that in my lights go bonkers. When I remove it the lights work fine. It has to have another purpose or it wouldn't be there. What is it and what does it do? I have changed all of the bulbs, several times.

I've always said that a person just has to be smarter than what he's working with. I guess I'd better quit saying that, huh?

*Edit*.....It's the chime module #SF8956001077.

On the bottom side of the fuse box? that is the seat belt buzzer, head light on buzzer, key buzzer, that can be left unplugged, but shouldn't have anything to do with the signals.

The proper name is Chime Buzzer Warning Module Relay. I talked to the Jeep service department Ft. Smith and it will not hurt to leave it out. It has been discontinued.

Looks like we posted about the same time. I know it shouldn't but it screws things up somehow. All is fine without it. Maybe because everything runs through the ignition switch. I hope the ignition switch is'nt going out.
