Stuck tach and fuel guage

Hello all. I am new to this forum and I want to thank you for allowing me to ask questions. I purchase a 2002 wrangler yesterday after wanting one for years. Today I noticed that the tach was stuck on 2100 rpm when the motor is running and the fuel guage bounces around. I was told that Jeep issued a TSB for a plug on the back of the cluster. Has anyone had this problem. I also found a large amout of water on the floor of the passenger side floor after driving around town . Please help me.

Welcome to the forum and to jeeps.

Yep tons of folks have run into the cluster problem. The plug for the wiring either comes loose, or the terminals corrode. Pull the cluster, see if the plug is loose. Also remove the plug and look at the terminals themselves. If you see anything but shiny metal, clean em, both the ones on the plug end and the ones on the cluster with contact cleaner (radio shack and most auto parts stores).

Also look at the terminals to make sure they are making a tight connection to each other. If not, take a small screwdriver and bend then a little to fit tighter.

All done, now apply a little dielectric compound, (R/S or auto parts stores) to the terminals. This helps insulate the terminals from water and corrosion.

Plug the plug back into the cluster firmly and make sure it's all the way in and tight.
Reassemble and you're done.


As for the water, couple of things it could be.
Worse is a leaking heater core. Check to make sure it's not antifreeze/coolant. And check you have it in the radiator when cool, as someone may have dumped it and just put water in it. Not good, and not cheap to fix.

Next up, was it raining, did you just wash it? the fresh air intake is the culprit there.
You have to pop the cowl off for this one. Easy to do.

Remove the wiper arms, noting their position on the windshield before. There are 5 screws on top of the cowl to remove, then open the hood, pull off the rubber weather strip where the hood sits on the cowl lip. There will be one screw on each side of the lip of the cowl to remove.
Close the hood, and pop off the cowl.

Flip the cowl over and you'll see a plastic baffle on it. If the seal is bad, it allows water to leak into the fresh air intake. Simple silicon sealer around the perimeter will take care of it.

Now take a look at the fresh air intake itself. There is sealer around it where it comes up through the actual cowl. If the sealer is in poor condition, another coat of sealer around it will take care of it. Reassemble, making sure you put the wipers back in the same spot and you are done.


Lastly, you could have an air conditioning drain problem.
If the drain is blocked, the water will back up in the case until it gets high enough to find a spot to leak out. Pop the hood, on the passenger side, down below the battery, you will see an plastic pipe sticking out, roughly 3/4" in diameter.

That's the a/c drain. CAREFULLY probe the inside of the drain to see if something is blocking it. Careful as the a/c evaporator is right there, and if you poke too hard, you damage the evaporator, and you'll end up with a lovely bill to replace it.

Now after all that, the drain again. It sticks straight out. And on some jeeps, when driving down the road, the airflow through the engine compartment will blow right into the tube, blowing the draining water back into the case. It can't get out so it fills up the case until it finds a place to leak out of. Simple fix, install a 90 degree turn hose on the end of the pipe, so it faces down.

Thank you for all the great information. This is my first jeep and I love it. Is the guage cluster something I can do or do I need to take it to a dealer.

Do it yourself, not hard at all. And as a Jeep owner, you need to know your ins and outs of your Jeep. It may save you from a long walk home some day.

Do yourself a favor and find a Factory service manual for it. Just about every you'll need to know is in there.

Ok, I pulled the dash and it was a very easy job. I unpluged both plugs and cleaned them with a good (CRC) contact cleaner. I applied the grease and put the dash back together. I was very dissapointed when I cranked my jeep, the tach moved to 2100 rpms and the gas gauge moves around like it has a mine of its own. I can tap on the glass and the gas guage works, however the tach is stuck. When I cut the motor off the tach goes to zero, but as soon as you crank the engine, 2100 rpms. Any ideas?
