After setting the alarm on my 2000 jeep grand cherokee the lift gate can be opened without setting the alarm off. The alarm is also disabled once the lift gate is opened
Hi Gloria, I'm glad to help!
Gloria, the most likely cause for no alarm when the liftgate is opened is usually because the controller does not see the liftgate open. 2 things can cause this. (1) The alarm switch on the liftgate could be bad. (2) The wiring going to the switch could be broken somewhere in the wiring. On the Jeeps its usually broken where the wiring is bending all the time between the liftgate and the body of the vehicle. If you pull the rubber insulator out you can then check the wiring. If the wiring is good then the next step would be to try an alarm switch for the liftgate. Hope this helps and have an awesome day Gloria.

There is a switch in the lift gate latch that closes when the gate is closed and turns off the light, this switch is defective, replace it and the light will go off.

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

Well My 94 Jeep Grand Cherokee had the same problem and we had to just cut into the lift gate panel from the inside. It required cutting plastic but with a 94 looks arent everything and a working lift gate was worth it. But then we pealed back this black plastic mat under the panel and lifted up on the release bar(verticle bar that lifts the latch) and once we got it open we adjusted a little clamp that had slipped. Dont adjust it too much or when u lock it it wont lock! But sorry i dont know the name of the parts. But then u can screw the panel back in and it wont look to bad besides some cuts.
