1995 Wrangler Speedometer not working

I bought a 1995 Jeep Wrangler back in 2005. Throughout the time I have had the the speedometer/odometer, for no apparent reason and regularity, will just stop working. Sometimes it lasts for less than a mile and other times for 50+. It went down for the count a week ago. All other guages and instruments lights are working fine. For now, I'm relying on the TAC. Fortuately, a long time ago in anticipation of this eventuality I wrote down "TAC=Whatever speeds in 4th & 5th" in incriments of 5, so I am good to continue operating temporarily.

Can anyone shed some light on troubleshooting for this kind of problem? I need to get her fixed this week if possible, but haven't a clue where to begin with this one (Haynes book wasn't much help on this one). I checked the wiring harness and all looks good there. Any help would be greatly appreciated.

Just had trouble with my 88. I followed the speedo cable to the transfer case and diconnected the connector at the transfer case(bolt holding a tab that was holding the metal connector) With the assembly off I checked the plastic gear that connects to the speedo wire. It was stripped. Quadratec has a new gear for cheap and this fixed my problem. (also corrected my speedo with since the 33" tire install) When you have the cable disonnected from the transfer case have a freind spin the output shaft and see if the gauge moves. That takes care of troubleshooting the gauge and cable. There are only a few things that can go wrong. the first three are the easiest to troubleshoot.

1.Bad gauge
2.Bad cable
3.Bad Gear - most likely your issue. Mine was visibly concaved and teeth were stripped.
4.Bad transfer case (unlikely)

His 95 is going to have a distance sensor, OP have you checked for codes. OBDI Error/Check Engine Codes - JeepForum.com Community Jeep Wiki Look there for what the codes mean. Your distance sensor is at the back of the t-case.

I had that happen a few times and it was always the sensor at the transfer case.

Hey Branton! That happened to me last year. This is what I did:
http://www.jeepforum.com/forum/f12/o...l#post11648750

It's really easy! If it's not a corroded ribbon, then check your sensor on your exhaust. Can't rmbr what the sensor name is.. I hope this helps you. -Shay

He is talking about the speedo sensor in the Tcase. We call it the VSS. Vehicle speed sensor.

take the 1 bolt out that holds the adapter to the transfer case. Pull it and the adapter housing and speedometer gear will come out. Turn the key on and use a drill to spin the gear and watch the speedometer. If it works the gear is clocked wrong. If it doesnt then you have a wiring issue.

could still be either one. If its clocked wrong the gears dont touch and you got nothing.. if you have a wiring problem the gears are turning but nothing is getting to the gage.

Speedo trouble

Not sure if you guys in the older YJ's are aware of this, the OP's Jeep (as well as my 95) use an electronic sensor instead of gear and cable. Most likely issue is the vss (vehicle speed sensor). I just had mine go out three days ago.
