Instrument Panel Issue?

I went out and started the Jeep up today, and noticed that none of the gauges worked, the check engine and air bag lights were on, and also is said No Bus on the odometer. It was cold out, and when I drove it a few miles everything kicked back on and was running normal. Could there be a short? I checked the fuse block and nothing was blown...I am lost on this one. Any suggestions?

I don't know how to fix it but my friend and me both have TJ's and they do it occasionally so your not alone.

its a common issue with the gauge cluster itself. There are two female mounted plugs behind the dash, and two corresponding male plugs built into the gauge cluster. The connection between those plug is loose, causing the gauges not to work.

When mine was doing it I would slap the top of the dash and they'd come to life, and maybe happen again a couple days later, or maybe three weeks sometimes. It was all about the connection.

You can take the cluster out, very easy to do with Philips screwdrivers and 1/4 hex head nutdrivers. The cluster pulls right out once you get to it. You'll see on the back two plug holes and about 12 contact pins per plug. These get dirty and worn a bit and loose contact. You can clean the plugs up that are on the dash still, and take the cluster inside and sit down at the table and push the pins over ever so slightly. Kind of like a regular wall plug in that gets loose and you push the prongs together so it fits tighter. Same concept, you are moving them just a hair to get them to contact better.

I sat down and used a small pointed screwdriver (more like a awl, or ice pick) and just gave each pin a slight push to the left (or right, don't matter, but go the same direction on all of them). If I had to put a measurement on it I'd say 1-2mm at most to get good contact again. The goal is when you push the cluster back on to the plugs in the dash they are situated to make better contact.

On a scale of 1-10 for difficulty, about a 1. Mine have been good ever since and its been about 6 months.

the rear taillight actually gets it ground from being bolted to the tub, so if you have a normal working turn signal I'd say it is grounded. if you take the three bolts mounting it to the tub (red circles) out you can pull about 10 inches of wire out, maybe check in that area for something wrong, or corrosion inside the light housing, they pull power and ground from each other and something funky in there may be screwing it up

now that i think about it and look a t my pic, if you are getting power to the blinker, then the back up should work unless two reasons

1) wrong bulb...should be a 2057, and back up bulb is a 1157

2) if the driver side is coming on then you know the sending unit up at the pedal is good, so it has to be somewhere in the wiring where it pig tails off from the driver side and goes to the passenger.

hope I am helping...check the bulb first!!

I figured out the problem. There was a pigtail hooked in to the factory plugs for trailer lights. The pigtail wasn't hooked up correct, and was in bad shape. I took that crap off off and hooked the factory plugs together and bam....the park light works.

I also took the milk jugs off the front and back....everyone of them was filled with dirt, and the bolts were rusted to high heaven.

Thanks for the info KEV...it led me to the solution to my problem!!!

idle is controlled by the idle air controller, when its running and the hood is up can you hear a sucking/vacuum noise? it would be right in front of the drivers area, under the hood, close to the intake and where the brake booster is.

Could be a vacuum leak or a stuck Idle air controller, which can be cleaned usually with a spray you can get from the auto parts store

Jerry sums it up here...

I don't usually believe in coincidences, when it comes to working on these things, but some times it does happen, just funny its while you are finishing up on two totally unrelated issues.
