Lost power to Dash on the way to work
Driving to work this morning, I noticed the radio started acting funky. About a minute later, I lose all power to the dashboard. Speedo is dead, radio dead, everything dead but AC is still running. Also noticed that the car lost a little power.
I smack the dash a few times and notice the speedo needle jump a bit but its still dead. I have no choice but to keep driving since I am 5 minutes away from work. The blinkers work and the headlights turn on and off.
I get to a light and decide to turn off the AC in case I am draining battery. As soon as I turn the AC off, the dashboard kicks back on and everything is working as intended. Turn the AC back on, everything dies, and I lose a good amount of power in the motor. Turn it off, and I am cruising along.
I get to work and park the car. I turn it off and crank it back on and it seems to start fine. I turn the car back off and put it in the ACC position. Radio on, AC off. I turn the AC on, radio stays on, but the oil light dims.
I dont have a voltmeter at work, but I am guessing either alternator or Battery. The alternator looks like a pain in the ***.
Any input besides checking voltages?

This could be associated with the "No Bus" problem...ie wiring harness oxidation/bad contacts. Check to see if it's throwing any codes.
In my '98, since about, oh 1998, the gauge cluster will intermittently/randomly die. A firm tap on the dash generally wakes her up from her slumber. I've never considered it a major issue, so have never fixed it. Sometimes Jeep just takes a nap.

Had the same problem but my whole gauge cluster was out, no radio, but the headlights and A/C worked fine. It was a fuse. Go to the fuse box under the hood and pull the fuses and see if any are blown

i have a similar problem but its a short in the overhead console. i can move it back and forth and kill all the dash components and gauges. the turn signals still work but won't show that on the dash.
