What is Liftgate?

The liftgate is part of the hydraulic system or electric gate on vehicles with trailers. These devices provide various services, such as loading and unloading materials and loading large vehicles into trucks.

These devices also have opening mechanisms that can be both manual and electric. The liftgate is crucial because it enables people to load and unload heavy objects easily, increasing their productivity and efficiency by reducing the number of trips they need to make.

I have created the infographic below that covers the typical Jeep Grand Cherokee power liftgate problems and how to fix them. (You are welcome to use and share but please credit back if you do so.)

Jeep Grand Cherokee Power Liftgate Problems And Fix

The Possible Reasons for the Jeep Grand Cherokee Power Lift-Gate Problems:

1. Obstructions Due to Dirt and Moisture:

The power liftgate in Jeeps holds a rubber lining around their frames. This rubber lining is helpful for better adjustment of the vehicle. However, this material is vulnerable and cannot withstand dust particles, debris, and moisture.

The water droplets can penetrate the control modules, leading to an electrical surge and an alternative flow for voltage resulting in short circuits and burning of the overall system.

The power liftgate faces problems in opening and closing due to such issues. In addition, the system lacks response toward the input signals of the key fob and manual units.

A person can fix this issue by cleaning rubber sides using a duster or a cleaning agent. It is recommended to avoid the accumulation of rainwater and keep the electrical module of the SUV dry from the inside.

2. Problem due to Broken Controls:

A push button with the key fob of jeeps can open and shut down the liftgates. An owner of the jeep can press them two times within 4-5 seconds, which can easily open the rear gate. A person can also close them within less than five seconds. But sometimes, the same key fob stops working due to battery drainage.

An issue is sometimes detected due to a broken switch resulting from incorrect manual controls and current fluctuations. In addition, a malfunctioning key fob sometimes needs to be fixed to coordinate with the installed sensors of the SUV, creating a problem.

A person facing this issue can check the battery of the key fob and can replace it with the drained battery. They can also check the switch and replace it with another compatible option.

A person facing these issues can also install the control buttons and upgrade the modules, costing around $2200-$8990.

3. Faulty Electrical Passage and Its Intermittent Action:

The power liftgate in the Jeep Grand Cherokee often shows erratic behavior. The liftgate opens after the input signals through push buttons and closes within seconds after this input. It is due to a blown-out fuse, excessive current load, or a modified voltage flow.

The excessive flow from the connected circuit is the main reason behind the malfunction. In addition, the drive in the system connects multiple electronic amenities and increases the current load, which can damage the fuse. This problem can be solved by assessing the instrument panel and fuse box.

Find out the fuse of 15 amperes and test the passage of electric current from it. If the light is absent during this test, it is a sign of malfunctioning, and the fuse will blow out. Remove the older piece and plug in a new fuse in its place.

The liftgate in the Jeep Grand Cherokee malfunctions due to an issue with electric wires. The cords can bend due to higher temperatures. You can take professional help and replace the broken and non-insulated wires to stabilize the system.

4. Malfunctioning Latch of Power Liftgate:

If there is a fault in the latch actuator, there can be a problem with the rear gate. The accumulation of debris in this region can damage the actuator within minutes. The latch actuator holds a specific mechanism for lifting the rear gate using a remote.

There is a lock actuator that mounts on the lower region of the gate. Grease and grime have shown a reduction in the performance of the actuator. The gates are sometimes opened without any input signals from manual controls.

A person can remove the problem by replacing the latch actuator to the remote-controlled gate:

  1. Access the bottom side of the gate and remove the screws.
  2. Remove the broken or worn-out actuator.
  3. Install a new option and connect the control module.

5. Damaged Motor of Power Liftgate:

The high-performance motor of 12 volts supplies steady power to the liftgate. A person can open and close the motor with constant torque. It has some electrical control units. This motor is small and vulnerable in size and can withstand the level of standard voltage.

It can malfunction due to excess current load and stops supporting the remote-controlled movement of the rear gate. The issue of hatch brakes can arise due to sudden changes in power. It becomes difficult for the person to use the broken 12-volt motor.

A person can replace the motor with mechanical help, which is effective in stabilizing the current flow.

6. Broken Button of Power Lift-Gate:

If there is a broken button on the power liftgate, a person can regulate it by pushing the center console button on the instrument panel. These buttons, when pressed manually, can send digital signals via computerized programs.

7. The Damaged Motor of the Power Lift-Gate:

The high-performance motor holds a 12-volt supply of steady power to the liftgate of the Jeep Grand Cherokee.

These push buttons have built-in switches that use electric power to regulate the system. Sometimes, the switches break due to incorrect and excessive usage.

8. Malfunctioned Sensors of Power Lift-Gate:

The electronically controlled system has a built-in sensor, a track, and a controlled module. The track of this electronically controlled system is explicitly designed and can be attached directly to the Jeep Grand Cherokee.

The sensors in the liftgate hold the ability to identify the signals and have specific requirements for moving the gate. Unfortunately, the excessive heat of the jeep can damage the sensors as they cannot withstand the signals.

When these sensors are used frequently, it can lead to high internal temperatures generating excess heat. It then becomes necessary to remove malfunctioning sensors to stabilize the system.

If you want the correct performance, adjusting the sensors in a specific network is better. If you want to improve the strength to withstand the electrical surge and excess heat, it is advised to improve the stability. A person can also take assistance from experts to achieve non-problematic results.
