Rear lift gate on 2011 Yukon only works with key fob. Friend mistakenly pushed down manually instead of pushing close button on rear lift gate . How can we fix it?


When the gate was used manually the inside button was deactivated. Look in owners manual or contact dealer to see how to activate switch.

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.

I have 2005 chevy tahoe my doors all licks but my liftgate door with window stays open use to lock w all my doors? I havent check anytjing yet? I cant lock it.


Here is how it works !
Liftgate Locking Operation
The lift gate 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 lift gate is locked anytime the vehicle is shifted out of park or when the vehicle is in motion.
The lift gate 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 lift gate lock function has been received by the BCM. The BCM will then ground the control side of the lift gate lock relay. This energizes the relay and allows voltage to be applied to the lift gate lock actuator lock control circuit. Since the other side of the lift gate lock actuator is connected to the normally closed contacts of the door unlock relay to ground, the lift gate will lock. When an unlock function occurs the BCM will ground the control side of the unlock relay and the rear doors and lift gate will unlock.
The BCM also runs diagnostics on the lift gate 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 lift gate lock circuit and that the lift gate is not locked. Faults that will set the DTC and cause the DIC to display the message could be any of the following:
?€¢
An open ECC fuse


?€¢
An open or short to ground in the lift gate lock relay battery positive voltage circuit


?€¢
A faulty lift gate lock relay


?€¢
An open or short to ground in the lift gate lock relay control circuit


?€¢
A short to ground in the lift gate lock actuator lock control circuit


?€¢
A faulty BCM

Lift gate open warning light sounds when temp is below 60


sounds like the cold temps cause the metal door to warp which causes an increased distance to the sensor that tells the computer the lift gate is open. The lift gate sensors should be adjusted to be closer together.

I have a 1993 dodge grand caravan that the lift gate won't release from the locking latch after it was banged into..


go inside to the lift gate and try to use a scewdriver to pry the latch loose while someone pushes the button or turns the key. it sounds like it's in a bind. you also may have to remove the cover panel from lift gate from the inside.

2004 grand caravan some dome lights stay on rest shut off normally


Is there perhaps a problem with the dome light switch on the lift gate? Close all the doors, open only the lift gate and find the switch on the lift gate frame (usually a rubber covered "bump") and press it in. You might have a loose wire shorting against the bodywork or the door is not depressing the switch properly.

2006 Tahoe Replace Liftgate fuse random alert- how to fix?


My info shows the ECC fuse 10Amp powers the Lift gate lock relay. this is the only Info I have so far. the ECC fuse is located in the instrument panel Fuse block. That fuse block should be at the left end of the dash. You have to have the drivers door open to access it. the fuse will be on the left side of the fuse block bottom corner just above the 25Amp circuit breaker for the LT doors. when you remove the fuse make sure the connection in the fuse block are not heated looking or that the fuse block itself is not melted looking. If so you have a loose connection there. you can try to close / tighten the connection with a small pick. bend the connection point closed so it will be tighter in the fuse when you install the fuse.

Liftgate won't open automatically


To open the lift gate manually, use the door unlock switch located on the drivers door. This should unlock the lift gate as well. Go to the lift gate and lift the handle to open the rear gate.

Your power lift gate is computer controlled. Sometimes there will be a faulty input sensor or part that will show the incorrect data to the computer, therefore the computer will not go through its normal functions.
In most cases its the problem of lift gate latch assembly.

To get it tested and confirmed there is a troubleshoot guide provided by the service center. To perform this troubleshooting guide you will require a scan tool to diagnose the exact problem.

the troubleshooting procedure is as follows:---

Please use the following information below when diagnosing an inoperative lift gate. Disconnect the connector at the lift gate latch assembly. With the lift gate latch connector disconnected, the 3 signals for the ratchet, pawl, and the sector should be inactive on the scan tool.

Install a 3A fused jumper wire between each signal circuit terminal (for the pawl, sector, and ratchet) and the ground circuit terminal 2. Monitor the scan tool as each individual circuit is jumped to ground, the scan tool should read "active".

If either tests above fails, check the wiring for the signal circuits, low reference circuit, or try a power lift gate control module from a known good vehicle. If both tests above pass, monitor the internal switch inputs in the lift gate latch assembly for proper operation.

3. A) with the lift gate in the open position, the ratchet and the pawl should read "active" and the sector should read "inactive"

B) With the lift gate in the secondary latched position, the pawl should read "Inactive" and the ratchet and sector should read "active"

C) With the lift gate fully closed, the pawl, ratchet, and the sector should all read "inactive".

4.If one of the internal lift gate latch assembly switch inputs are not reading correctly in one of the positions above and the vehicles passes test 1 and 2 above. Replace the lift gate latch assembly.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

This should help you.Thanks.Helpmech.
