Question about 2000 Jeep Grand Cherokee
My jeep has recently started acting up and i have no idea why. The radio has begun flickering on and off randomly and for random durations. It has also reset itself a couple times, turning off completely and then resuming again. I noticed that the voltage meter on the instrument panel has been swiveling back and forth from its normal position. It usually runs around 14 but will swivel from anywhere between 12.75 to 16.50. Lastly the horn acts up a little also after it has sat for awhile. The horn kinda does this little short burst almost like i am activating the alarm. When i had the fuse panel under the hood open i heard a little surge of power run through and the horn went off.
What year and model? A standard answer will be you have an electrical problem possibly an alternator or a poor ground when you lose power to the radio it will reset has the battery died recently?

Alarm Module Reset Procedure
NOTE: This information applies to a Vehicle Theft Security System (VTSS) that was armed when the battery was disconnected and reconnected.
When the armed VTSS senses that the battery has been disconnected and reconnected, it enters its power-up mode. In the power-up mode the alarm system remains armed following a battery failure or disconnect. If the VTSS was armed prior to a battery disconnect or failure, the system will have to be actively or passively disarmed following a battery reconnection.
The power-up mode will also apply if the battery goes dead while the system is armed and battery jump-starting is attempted. The engine no-run feature will prevent the engine from starting until the alarm system has been actively or passively disarmed.
Passive disarming of the Vehicle Theft Security System (VTSS) occurs when the vehicle is unlocked using the key to unlock either front door or the lift gate. Active disarming of the VTSS occurs when the vehicle is unlocked by depressing the Unlock button of the Remote Keyless Entry (RKE) transmitter.
Once the alarm has been activated (horn sounding, lights flashing, and the engine no-run feature), either disarming method will deactivate the alarm.
Depressing the Panic button (if equipped) on the RKE transmitter will also disarm the VTSS, but the horn will sound and the lights will flash for about three minutes as part of the Panic feature. The horn and lights can be stopped by pressing any of the RKE transmitter's buttons or driving the vehicle above 15 mph.

Others have had this problem too. Most times it's a loose connection behind the gauge cluster.:
When you take the dash apart to get at the back of the guage you'll see that the connectors for the panel are attached to a molded piece of black plastic and the panel sits on top of them. The solution I used was to actually cut the plastic back (you can break it back too...) and insert the plugs tightly, then put a dab of hot glue on top and bottom to keep them from backing out. It keeps them nice and snug and you can remove them in one minute with a razor knife if you need to. After about a year I haven't had the problem since.
BTW - your mileage is not accurate if you have this problem. I noticed that when the gauges are off, it does not count mileage...went about 5000k miles without an oil change once...Just some addt'l info.
I know it's not a factory fix, but it costs about $1 for a glue stick and it only takes about 30min.
Hope it helps you.

I think I have found the problem. When I wiggle the ignition switch the turn signals and radio go on and off so I feel the issue is in the ignition switch. From what I understand the actual electronics for the switch are at the base of the sterring column behind the lower dash panel and is connected by a rod that may need adjusting.

I had a similar problem with my 2000 Jeep TJ and I found the problem in the wiring harness under the hood.several wires were corroded and almost burnt off.If you remove the black tape which keeps the harness bundled together and if you see evidence of "green" type powder or "gook" it's most likely where the wires have faulted.
