Well I thought my first thread would be something cooler than this, but I need the mechanics of the planet to step forward and help. I have a 1994 Jeep Grand Cherokee. Tonight while driving I noticed by blinkers had stopped working. No click, no faster click, no flash on the dashboard, no light in the front or back. My headlights and taillights work fine. My flashers also do not work nor is any sound made when I put them on. I checked the fuses (flashers and blinkers) and unfortunately that's not it.

No my Jeep does not need antifreeze, yes I do need help as I'm driving back from STL to Wichita in a few days to see the family for Easter and something tells me I'll draw the attention of a trooper or two if I make the drive without a single turn signal. Thanks in advance for any advice. :clap:

Use hand signals.

Replace the flasher. that is what it sounds like to me. should be near the fuse box. could be anywhere, tho.

Is this the flasher unit you are talking about? If so what does this part usually look like and is it an easy fix?

They're about 1" round things that plug in to your fuse box, or usually somewhere close to it. Very easy to fix.

I can't believe none of these posers have told you to change the blinker fluid.

Blinker fluid. Great, and where do I put that? Just add it to the gas?

Alright, sounds like I need to call O'Reilly's in the morning and check into a flasher unit. Any 2nd guesses so in case that one doesn't pan out?

This seems to make it sound like the flasher unit may be behind the fuse panel? Would that make sense?

Behind it? That doesn't make sense. Sometimes they're plugged right into the fuse panel:

Other times they're plugged into a nearby sub-panel, and I've also seen them just hanging plugged into a wire. They're almost always right around the fuse panel area though. You shouldn't have to look far.

:hmmm: Now that you mention that, it seems odd that they would both go bad at the same time.

Not sure about Jeep,
They have controls under hood as well?? My Nissans had relays etc near firewall in engine area.

None ever went out though...

stlchiefs

Well, no luck. But, I was searching with a flashlight in the dark. Hopefully I find someone knowledgeable at O'Reilly's who knows where it's on my Jeep.

If you look between the steering column and the fuse box you should see the round blinker relay. It is sometimes up in the wiring that goes into the steering column or above the fuse box, but you should be able to find and change it yourself.

If you need to, go to your auto parts store and they will have a manual that shows the exact location and the part number that you need. The turn signals and hazards have been on the same relay in all of my vehicles. Good luck.

My fuse box is on the side of the dash on the Passenger side, so it's no where near the steering column. Sounds like there's a couple of places it could be and I need an 'expert' to take a peek.

It might be under the hood. In the "Power Distribution Box". I think it's on the drivers side, mounted right next to the fender. Look for the black plastic box. On the underside of the lid it should tell you what's what.


Edit: Take a look at your owners manual, it should tell you where the flasher is.

Yeah, I know what box you're talking about. It's above the battery and below the engine coolant overflow on the passenger side. There's a number of relays and a few fuses in there. You think it could be in there?

It's more than likely in the wiring behind the fuse block, between the steering column and the kick panel. You'll have to twist your neck around so you can look up into the dash. But if you can't find it there then i'd ck the one under the hood.

I'm not going to lie, I tried that earlier during my 5 minute intermission. Since it's dark out the lighting from the flashlight sucked so the pictures weren't worth a damn. I figured I'd just catch crap for posting the worthless pics and gave up on it. Here's the one I took of my fuse box.

It is time to look into the Chilton(?) manual to find the exact location of the turn signal relay. Most automotive stores should be able to look up the location for you and sell you the relay at the same time.

I still think it is around the steering column, up behind the dash.

stlchiefs, is your radio and windshield wipers still working?

Reason why I ask is that there is also an accessory power relay that controls the signals, radio "and" wipers for Jeeps.

I know my radio is working, haven't checked my wipers.

Those large silver things could very likely be them. Bust them out with a hammer immediately.

I would check in the power distribution box under the hood.

Is there any way to tell if a relay (I believe that's what the bigger silver fuse like things are) is bad or do you just have to swap them out an see?

I had a 93 Jeep Grand Cherokee, and now have a 2002 of same.
Never had that problem. Did burn through several batteries, Jeeps seem to be hard on batteries for some reason.
There are 2 fuseboxes, one is under the dash on the passenger side, right wall, and the other is under the hood, a rectangular black box, by the battery and anti-freeze overflow tank.

Maybe try this discussion thread, might find a similar problem there:
