WARNING: This page is about a different car, the 2012 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.

Rear Compartment Lid Latch

Ignition OFF, disconnect the harness connector at the rear compartment lid latch.
Install a 10 amp fused jumper wire between the control terminal 4 and 12 volts. Install a jumper wire between the ground terminal 3 and ground. Verify the rear compartment lid latch activates.
- If the latch does not perform as specified, replace the rear compartment lid latch.

Rear Compartment Lid Release Switch

Ignition OFF, disconnect the harness connector at the rear compartment lid release switch.
Test for infinite resistance between the signal terminal C and the ground terminal A with the switch in the open position.
- If less than the specified value, replace the rear compartment lid release switch.
Test for less than 2 ohms of between the signal terminal C and the ground terminal A with the switch in the closed position.
- If greater than the specified range, replace the rear compartment lid release switch.
Test for infinite resistance between each terminal and the lid release switch housing/case.
- If less than the specified value, replace the rear compartment lid release switch.

Relay Test

Ignition OFF, disconnect the TRUNK relay.
Test for 65-90 ohms between terminals 85 and 86.
- If not the specified range, replace the relay.
Test for infinite resistance between the following terminals:
- 30 and 86
- 30 and 87
- 30 and 85
- 85 and 87
- If not the specified value, replace the relay.
Install a 10-amp fused jumper wire between the relay terminal 85 and 12 volts. Install a jumper wire between relay terminal 86 and ground. Test for less than 2 ohms between terminals 30 and 87.
- If greater than the specified range, replace the relay.
