Turn signals don't work but flashers do ??? 87 Mj 4.0


Recommended Posts

Does the right turn arrow come on when you turn on the parking/head lights? Check to make sure you've got the right bulbs front and rear, and that they work. Should be 2057's or 1157's.

 

As for the rest of your dash lights, could be related to the turn signal, might not be. Did you make sure the dimmer switch isn't turned down, and that the fuse was good?

The only dash lights I have are the turn signals and high beams I checked the fuses they are still good bu, the turn signals (tail lights and upfront ) stay on even when clicked to the right . The left blinks no problem. The hazards work fine which boggles my mind

Did this just suddenly happen?

 

Have you checked the bulbs? I've got a similar thing regarding the turn signal indicator staying on solid, just happened a week or so ago. But my front turn signal/parking lamp is burnt out on that side. Haven't got around to changing it yet due to the season.

 

As for the dash lights not coming on, does anything happen at all when you turn the dimmer switch?

Okay guys I have no dash lights except the turn signals and high beam on/off when I flick the turn signal to go right it just stays on and doesn't blink when I flick it to go left it blinks ? The flashers work fine tho ?????What is going on ???? 87 Mj 4.0

The 4-way hazards use a separate flasher from the turn signals. You probably need a new flasher for the turns. You also may have one or more turn lights burned out, which will lock up the standard flasher (unless you have a heavy-duty flasher such as used in the trailer tow option).

 

As to the dash lights, have you tried rotating the headlight knob? It's a dimmer, and all the way in one direction (I've forgotten which way) turns them off completely.

I'll have to just order a new flasher and get a few bulbs all of them should be replaced after sitting so long anyway , as far as the dimmer switch I replaced it and tried adjusting it . I didn't notice any corrosion on the back of the cluster the bulbs look fine I'm thinking there's a break in one of the wires that goes to the cluster
