I have a 2000 jeep grand cherokee, the lights are flashing on and off while its in the drivway, it also does it somtimes driving down the road, they dont do it all the time just every other day, what could it be?

You have an exposer in the wire somewhere touching metal. I would assume in the door where the wires loom into the rubber seal but you will have to trace the short down. Or pay a mechanic $65-$90 hour do it for you.

I had the same exact problem and jeep looked at it over a dozen times. Jeep replaced the ignition switch and computer but they could never reproduce the problem, of course. I kept bothering Jeep until they replaced part of the wiring harness between the ignition switch the next conection. Problem solved. I had always said that it was a short in the wiring harness but they are too reliant on the in dash computer to tell them the problem. I hope this helps. P.S. this problem will kill your battery.

Sounds like the fluid is low...have you checked it? (check running in park, warmed up)

Check fuel filter and fule pump

check lug nuts. then have brakes checked if lugs are OK.

I think there is a TSB on that problem. If the wind is coming from the passanger side then roll the window all the way down. Put a 2X4 in the door jam. So the 2X4 will be inbetween the the door and the jeep. Push on the top of the door like you are trying to close the door. What you are trying to do and slightly bend the top of the door toward the jeep. But just do it a little at a time.

it is a problem with the electric panel...i had the same problem with my jeep grand cherokee 2005 and took it to the dealer and they covered it under the warranty

If this is an after market alarm it could have been turned off.
