Lift Gate Not Working: A Comprehensive Guide to Troubleshooting Common Issues

Aliftgate is an essential component for many trucks, especially those used in logistics and delivery services because it facilitates the easy loading and unloading of heavy cargo.

However, like any mechanical system, liftgates can encounter issues that may hinder their performance. Keep in mind that many of these issues can also be avoided by conducting proper maintenance on your liftgate.

This comprehensive guide will help you troubleshoot common liftgate problems and provide solutions to get your liftgate back in working order. We'll cover troubleshooting tips for liftgate switches, master fuses, hydraulics, solenoids, and more.  

Common Lift Gate Issues and How to Deal With Them

• Liftgate Won't Operate at All
  
  If your liftgate isn't operating, check the power supply. Ensure the vehicle battery is charged and that the liftgate's power switch is turned on. Look for any blown fuses or tripped circuit breakers.
  
  
  
• Liftgate Moves Slowly
  
  A liftgate that moves slowly could be due to low hydraulic fluid levels or a weak battery. Check the hydraulic fluid reservoir and top it off if necessary. Ensure your battery is fully charged and in good condition.
  
  
  
• Liftgate Stuck in One Position
  
  This issue might be related to the hydraulic system or a mechanical blockage. Inspect the hydraulic cylinders for leaks or damage and ensure there are no obstructions in the liftgate's path.
  
  
  
• Liftgate Makes Unusual Noises
  
  Unusual noises during liftgate operation often indicate mechanical wear or a hydraulic issue. Inspect all moving parts for signs of wear and tear, and check the hydraulic fluid for contamination or low levels.

The liftgate switch is crucial for operation. If your liftgate isn't responding to the switch:

• Check the Connection
  
  Ensure the switch is securely connected to the liftgate's control system.
  
  
  
• Inspect for Damage
  
  Look for any visible damage or wear on the switch.
  
  
  
• Test the Switch

• Locate the breaker
  
  Refer to your vehicle’s or liftgate's manual to find the resettable circuit breaker.
  
  
  
• Inspect the breaker
  
  Check if the breaker has been triggered. If so, reset it by following the manufacturer's instructions.
  
  
  
• Replace the breaker
  
  If the breaker is still malfunctioning, consider replacing it with one of the same amperage.
  
  
  
• Possible fuse
  
  The issue may be a fuse on the power wire of the switch. When present, make sure it is operational or needs replacement.
  

Liftgate Hydraulics Troubleshooting

Hydraulic issues can significantly impact liftgate performance. To troubleshoot:

• Check Fluid Levels
  
  Ensure the hydraulic fluid reservoir is full.
  
  
  
• Inspect for Leaks
  
  Look for any hydraulic fluid leaks around the cylinders, hoses, and connections.
  
  
  
• Test the Pump
  
  If the pump isn’t working, listen for any abnormal sounds, which may indicate a problem.
  

How Do I Know If My Liftgate Solenoid is Bad?

A faulty solenoid can prevent your liftgate from operating. Signs of a bad solenoid include:

• No Clicking Sound
  
  Normally, you should hear a clicking sound when the liftgate switch is activated. If you don't, the solenoid might be faulty.
  
  
  
• Solenoid Testing
  
  Use a multimeter make sure proper power is coming to the solenoid. Also, make sure the solenoid is properly grounded.
  
  Once verified, check for SWITCHED wire power and follow these instructions:
  
  1. If proper power is coming in, proper ground is established, yet NO power to the switch post when activated - test switch and harness.
  
  2. If proper power is coming in, the proper ground is established, and proper power to the switch post when activated is present - yet no power is transferred to the OUT post of the solenoid - the solenoid needs replacement.
  
  3. If proper power is coming in, proper ground is established, proper power to the switch post when activated is present - and proper power is transferred to the OUT post of the solenoid - Test the motor as it may be faulty.
  
  
  
• Intermittent Operation
  
  This may happen due to several reasons, including: faulty solenoid, bad ground or power connection, failing circuit breaker, damaged or faulty switch or harness. Therefore, the best thing to do might be to go to an expert for a full revision.
