GATE light on and alarm sounding

I have to lock the jeep this morning without the alarm, the gate light indicator wont go out. Where is the sensor could it just be dirty [sand] or something. any ideas? I am going to to take some brake cleaner and air to it and see what happens.

Reset computer

Try disconnecting the neg terminal from the battery and wait 5 minutes. It will reset the computer, worth a try and it cost nothing.

Good luck and let the board know if it works

NUMBER: 08-022-07

GROUP: Electrical

DATE: September 15, 2007

SUBJECT:
Intermittent Illumination Of The Courtesy Lamps And Liftgate Ajar Indicator With Chime Tone

OVERVIEW:
This bulletin involves switching the wires in the liftgate ajar switch connector.

MODELS:
2007 - 2008 (KA) Nitro

2008 (KK) Liberty

2008 (KK) Cherokee (International)

2007 - 2008 (WK) Grand Cherokee

2006 - 2008 (XK) Commander

2006 - 2008 (XH) Commander (International markets)

2006-2007 (HB) Durango

2007 (HG) Aspen

2008 (RT) Caravan/Town & Country
NOTE :This bulletin applies to all KA/KK vehicles built before August 18, 2007 (MDH 0818XX) and WK/WH vehicles built before September 11, 2007 (MDH 0911XX),

NOTE :This bulletin applies to XK/XH vehicles built before September 11, 2007 (MDH 0911XX) and RT vehicles built before October 22, 2007 (MDH 1022XX) built without sales code JRC (powerlift gate).

SYMPTOM/CONDITION:

Customers may observe illumination of the courtesy lamps, a chime tone and the liftgate ajar indicator message illumination when the liftgate is not open. This is caused by intermittent contact of the liftgate open sensing wire closing the circuit to ground. Swapping the wires will make the intermittent contact with the body on the ground side wire eliminating the false illumination and indicator messages.

DIAGNOSIS:

If the above condition is present, perform the Repair Procedure.

From my manual:

LIFTGATE

A liftgate ajar switch is standard equipment on this vehicle. The switch is concealed within and integral to the liftgate latch unit. The switch is a momentary leaf contact-type unit that is actuated by the liftgate latch mechanism. An integral connector receptacle on the liftgate latch connects the liftgate ajar switch to the vehicle electrical system through the liftgate wire harness.

The liftgate ajar switch cannot be adjusted or repaired and, if ineffective or damaged, the liftgate latch unit must be replaced.





4.Remove the three bolts (4) from the lift gate latch (3).
5.Disconnect the electrical connectors (5).
6.Disconnect the cable (2) from the latch (3).
7.Remove the lift gate latch (3) from the lift gate (1).

Thank you for this information. I think I can replace this myself - however, do you have instructions for how to remove the interior liftgate panel to access this liftgate latch unit? Appreciate your post very much!

I had a problem with my lift gate last year, was due to water damage affecting the sensor. My light would stay on and my jeep would think a door was open or whatever. Was kind of expensive to fix so I just had them disconnect it.

I had the same issue, 4 times. The flipper glass was leaking allowing water to get into the switch assy. There is a TSB for this that includes changing the flipper glass seal and adding a strip of door seal material across the top of the glass. It's fixed now and the new glass seal is a good bit thicker.

Yeah, the seal was my issue too. My sub would rattle it loose and I would have to jam it back up there everyday... But the days I didn't and it rained, a good amount of water could get in. The stripping would be filled with water. Put some strong double sided tape around the lip and it stays fine now.

That's it. Even though you taped up the weather strip, water can still get through the seal because it isn't tight. That's why it would vibrate down. It would've done that without the vibration, mine did.

Two screws at the lower face and start popping the thing loose

I understand that you may not want someone else to work on your jeep but the dealer will fix it for free if it's still under warranty. I don't think they'll warranty it after you fix it when it happens again. You're going to need both latch assemblies and the new style window seal.

I have the same problem with my 2010 seems to be a common problem, I have seen it recurring on the web. I have a lift gate message that will not go out and my interior lights stay on. I am going to have to check the seal around the rear glass, I haven't noticed any water in the back, my 03 leaked like a sieve. I guess I am going to have to replace the whole latch mechanism.

The water leaks around the flipper glass, there's a TSB for it. They replaced the gate seal, flipper glass seal, both latches and added a small weather strip to the top of my flipper glass. I don't know if TSB's are covered after 36 months but it'd be worth looking into.

According to my dealer the TSB is not covered by any warranty. Just replaced the rear flipper glass seal in my 2010. It was letting water in around the latch for the glass. It killed the "gate ajar" sensor on my latch. You can unplug it. The alarm will go out but you will also loose the interior lights going on when you open the hatch. Not a big deal to me. I am waiting for spring to make sure the seal replacement gets all the water intrusion, then I will replace the latch.
