Generally speaking, the causes of control failure in long-term use of liftgate are as follows:

      1. The contact point of the liftgate relay is stuck. At this time, we need to replace the relay.

      2. If the liftgate travel is fretting, the switch fails or the sheet is deformed. If this is the case, the microswitch or contact plate needs to be replaced.

      3. If the screw of backing plate is loose, it is easy to cause the displacement of the backing plate. In this case, it is only necessary to tighten the slider screw and reset the backup plate.

      4. The liftgate slider or nut cannot move with the screw rod rotation, which may be due to the need for lubrication or other solutions.

      5. If the lifting threshold gear is damaged, it is necessary to replace the limiting gear.

      6. The up and down keys of the liftgate are stuck. This is simple. Replace the button if the button is broken.
