Check the ground wire between the socket and the vehicle chassis and make sure that the connection is good.
Piper Halliwell from "Charmed" drove three different Jeep vehicles throughout the series: a 1999 Jeep Grand Cherokee Limited, a silver 2001 Jeep Grand Cherokee Laredo, and a later model 2001 Jeep Grand Cherokee Laredo.

The switch is probably bad or you aren't turning the knob all the way off.
Your clicking msy me your sc duct door acuator with a strip gear and for your gauge problem snd radio sounds like a bad ground check and make sure you have a ground from your battery to your engine and from your engine to the frame and from your frame to your body.
my Oldsmobile alero did the same thing. It turned out to be as simple as a blown bulb in my tail light.
I had the same problem in my 99.turned out to be the crankshaft sensor. Hope this helps

I Currently own a 1996 Jeep Grand Cherokee Laredo and it has or had the same problem... What i Did was find the computer and messed with the cables a bit. The truck turned rite on. The problem is that in order to keep it running i put tape going around the computer and cables... it works as if they were just loose or something... i don't know what the name for the cables is and am currently trying to find that out....
The by-pass switch on the dash is turned on.
I have a 99 Grand Cherokee and the driving lights are turned on by pulling on the button located at the top of the head light switch on the left side of the column, Note that the driving lights will only work with the low beams and will turn off when you switch to high beams. If you search the net you can find a way to have the driving lights and high beams on at the same time, this usually involves modifying a relay under the hood.
Needs a battery, most likely. Have the alternator checked after replacing the battery. Additional Info: It could also be a loose battery connection - check the battery cable clamps. Also, if the battery needs to be replaced, lock and unlock your doors with the key as the alarm system activates itself when a battery is removed, disconnected or replaced. Cycling the door lock cylinders resets the alarm.
