Liftgate Switch Malfunction

WARNING: This page is about a different car, the 2008 Pontiac Torrent and 2008 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the liftgate switch.
  2. Test for less than 1 ohm between the ground circuit terminal C and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify the scan tool Int Trunk/Liftglass Sw. parameter is Inactive.
    • If not the specified parameter, test the signal circuit terminal A for a short to ground. If the circuit tests normal, replace the BCM.
  4. Install a 3A fused jumper wire between the signal circuit terminal A and the ground circuit terminal C. Verify the scan tool Int Trunk/Liftglass Sw. parameter is Active.
    • If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.
  5. If all circuits test normal, test or replace the liftgate switch.
