89 MJ No Turn Signals

[Barnes2001]

I’m having a problem with getting my turn signals to work. Hazards do work. Changed the head lamp switch, changed multi function switch, and checked all the fuses. The fuse block is all good no clutch fluid has been on the block it’s all clean. I have finally come to the road block.

Long day

It’s an 89

I am trying to fix my girlfriend’s ‘89 Eliminator with similar issue but only on the left side. Brake lights, running lights and hazards work but just not the rear left turn signal. I changed fuses, bulbs, cleaned bulb sockets…

Hazard flasher? It is separate from the turn signals.

Sounds like either a bad ground, bad turn signal switch or bad sockets

[BlueJeans]

Thank you jdog I will start with those next

there should be links to the factory shop manuals in the link in my signature.  If you haven't yet, run through all of Cruiser's MJ tips.  most are electrical in nature. 

 

I don't know how to @  Ohm because he used a symbol in his name that's not on my keyboard.    what the heck.

Aside: Pete, to get Ω, press and hold the Alt key, then type 234, then release the alt key. There are lots of altcode symbols.

I JUST had the same problem except with my front drivers-side; it turned out to be bad sockets. You can take them apart by forcing the two pieces of plastic apart, pulling out the wires and contacts then sanding them lightly with 600 grit. You'll have to glue the plastic back together (I used gorilla glue as it expands and creates a tight seal) but the wires and contacts will just clip back in. If you don't want to spend the 20 minutes, you can just replace them. Lordco has stock ones and if you're in the US I'm sure RockAuto would. Should be about 7 bucks...

They don’t do anything at all nor do I have running lights or dash lights. Hazards do work

Check for power on both sides of the turn fuse with the fuse in, if power there, is there power at the turn signal flasher

Do the Brake Lights work?

Yes

[Pete M]

so it sounds like we need to check for power coming out of the turn signal switch.  I don't know which wires colors to check though.  do you have the factory electrical manual downloaded yet?

KEY OFF.
Depress brake pedal.
Using T/S SW set to RH side, can you turn OFF the RH rear bulbs?
Try same thing for the LH side.

Hey, I don't mean to hijack the thread, but I'm having the exact same problem as him with an 87. What would it point to if I can turn off the brake light with the turn signal? I'd figure the switch is good in that case. I'm not sure it's the flasher, though. I tried swapping out the turn signal flasher for the hazard flasher, but no dice.

What do you mean? Our MJs are wired that way so the brake light in the rear gets overridden to blink while braking. Otherwise the person behind ya might not know what youre doing.  Now if your front stops blinking while youre braking then there is a problem and could point to a crossed wire.

[Pete M]

have you checked all the sockets?  certain your rear bulbs are the correct dual filaments?
