Question about 1995 GMC Jimmy

3 Answers

1995 Jimmy 4d 4wd rear lift gate will not open -

....the upper (glass) part of the liftgate will not open. I can hear the actuator activate and cycle through the opening cycle but the latch for the upper glass liftgate does not open. I'm sure it's a mechanical connection and can be fixed but I cannot get the latch to spring. I puulled the inside plastic trim back and I can see the latch - tried to spring it with a small screwdriver - no joy. .... been looking at the sawzall but I thought I try here first

Help

    ...the latch can be sprung .... the upper latch mechanism can be sprung by depressing the lever just inside the bracket cowling behind the inside the plastic tailgate cover. The lever is well hidden so just tuck an allen key wrench behind the metal cowling on the left side (from inside the Jimmy) and push down.



    .... then again there is always the sawzall !!!!!

I was able to get two wedges between the glass and the plastic trim. From that I used a scope to see inside and find the mechanism to release the window. Look for the one piece of plastic in the mechanism. The level has to be pushed toward the driver side of the car. Once I got the glass open, I removed the handle, and two screws from each side of the trim and removed the trim.

Once the trim was removed I had a small opening and could see the problem. The end of the latch has a small blue plastic (why plastic??) catch that broke.

Rather than taking the door apart and finding a replacement, I heated a screw driver and made a slot in the plastic. Next I used a heavy duty zip tie and connected the two pieces (plastic catch and metal part that opens the latch). I left some slack in the connection and all works great.

Not sure how long this will last, but for now I have the back opening. I will look at replacing the plastic piece, but not sure if a total new mechanism is needed.

Stan, I had the same problem with a 97 Jimmy. This fix worked well. The only change I made was to drill the plastic tongue with a 3/32" bit instead of subjecting the clip to heat that might heat stress the plastic. The clip is accessible through a cut out in the tailgate inner shell. I fastened the clip to the latch with light gauge machine wire.

Sawzall bad idea you could have someone push the button to open it while you watch the actuator and see how it opens the latch and that should tell you how to do it unless the latch failed inside it then the sawzall might be a good idea

Need to replace the liftgate switch, where can I get instructions to do that?


How do you know it need's a switch ?
Rear Hatch/Gate Description and Operation
The lift gate can be opened by operating the switch on the instrument panel. Battery voltage is supplied to the lift gate actuator through the body control module (BCM). The BCM will pulse the lift gate actuator when a release input is received through the key fob, or the instrument panel switch. Did you test voltages ? Check for BCM DTC'S - diagnostic trouble codes ?
Circuit/System Description
The lift gate switch is an input to the body control module (BCM). The BCM supplies battery voltage to the signal circuit and when the lift gate switch is activated the signal circuit voltage goes low. The BCM controls the lift gate release actuator assembly through the LIFTGATE relay. When the lift gate switch signal is activated, the BCM enables the LIFTGATE relay by applying battery voltage to the lift gate relay circuit and the relay is energized when the BCM grounds the LIFTGATE relay control circuit. When the relay is energized battery voltage is supplied to the lift gate release actuator assembly through the lift gate release actuator control circuit.

Rear hatch keeps opens while driving...


Unless you have electrical diagnostic skills , I suggest you take this to the dealer ! The lift gate can be opened by operating the switch on the instrument panel. Battery voltage is supplied to the liftgate actuator through the body control module (BCM). The BCM will pulse the lift gate actuator when a release input is received through the key fob, or the instrument panel switch.
The body control module (BCM) receives an input from the liftgate ajar assembly. The ajar assembly is normally open when the liftgate is fully closed. When the liftgate is opened, the ajar assembly contacts close providing a path to ground. The driver information center (DIC) illuminates the rear access open message when the gate is open. The instrument panel cluster (IPC) receives a serial data message from the BCM indicating the liftgate ajar status. If this message is displayed and the vehicle speed is greater than 8 km/h (5 mph), a chime will sound.
It could be ajar switch is bad .

The rear lift gate on my 2006 Lincoln Navigator will not open automatically or manually and there appears to be no way to access anything inside the door from inside or out.


POWER LIFT-GATE OPERATION - To open the optional power liftgate, push the button on the instrument panel , press on your five-button key fob (if equipped), or press and release the control located in the left rear quarter panel (Figure B). To unlatch the liftgate glass, push the button ) under the center of the license plate lamp shield, or press on your five-button key fob. Do not open the liftgate or the liftgate glass in a garage or other enclosed area with a low ceiling. Keep clear of the liftgate when operating the rear switch. To open the liftgate manually, pull the handle located on the liftgate to release the liftgate from the vehicle. The power system will take over when you release the handle. To close, make certain the rear window is closed, and then pull down the liftgate a few inches to activate power closing. Closing the gate rapidly or more than a few inches may activate the obstacle detection feature and stop the power system.------------ Also click this link for more help:--- http://technoanswers.blogspot.com/2011/05/power-liftgate-on-will-not-open-on.html ------------ This should help.Keep updated.Thanks.Helpmech.

Rear liftgate on wagon will not open with remote or dash release. Can't find a fuse that is for the liftgate. Will open with key.


Hi,

This model actually had a recall on the lift gate actuators as they did give problems. The best why to see if it is the actuator or the wiring is to check for power to the lift gate actuator which is in the liftgate, and try to use the remote etc to see if there is power to it.

If there is power to the actuator then you will need to replace the actuator.

Thanks

2006 Tahoe Z71 Lift Gate Will Not Unlock With Remote

rear door hatch lock repair GMC Chevrolet
chevy tahoe lift gate not opening
The liftgate will lock any time the vehicle is shifted out of park on vehicles equipped with an automatic transmission and at vehicle speeds exceeding 5 kph with manual transmission. This happens in conjunction with auto door locks if enabled or independently of auto door locks if the feature is disabled. This ensures that the liftgate is locked anytime the vehicle is shifted out of park or when the vehicle is in motion.
The liftgate lock relay supply and coil sides receive a constant voltage through the battery voltage supply circuit and the ECC fuse. The normally closed contact is connected to ground and the control side is connected to the body control module (BCM). A lock function will occur when a door lock switch activation, keyless entry lock transmission, auto door lock function or a liftgate lock function has been received by the BCM. The BCM will then ground the control side of the liftgate lock relay. This energizes the relay and allows voltage to be applied to the liftgate lock actuator lock control circuit. Since the other side of the liftgate lock actuator is connected to the normally closed contacts of the door unlock relay to ground, the liftgate will lock. When an unlock function occurs the BCM will ground the control side of the unlock relay and the rear doors and liftgate will unlock.
The BCM also runs diagnostics on the liftgate lock relay control circuit and will set DTC B3825 as current and also send a Class 2 message to the DIC. The DIC will display REPLACE LIFTGATE FUSE to inform the driver that a fault has been detected in the liftgate lock circuit and that the liftgate is not locked. Faults that will set the DTC and cause the DIC to display the message could be any of the following
