GM Service Manual Online
For 1990-2009 cars only

Caution: It can be dangerous to drive with the liftglass or liftgate open because carbon monoxide (CO) gas can come into your vehicle. You cannot see or smell CO. It can cause unconsciousness and even death.

If you must drive with the liftglass or liftgate open, or if electrical wiring or other cable connections must pass through the seal between the body and the liftglass or liftgate:

   • Make sure all other windows are shut.
   • Turn the fan on your heating or cooling system to its highest speed with the recirculation mode off. That will force outside air into your vehicle. See Dual Automatic Climate Control System .
   • If you have air outlets on or under the instrument panel, open them all the way.
   • If your vehicle is equipped with a power liftgate, disable the power liftgate function.
See Engine Exhaust .

See Power Liftgate for more information on how to use the power liftgate.

To unlock the liftgate, use the power door lock switch or press the door unlock button on the Remote Keyless Entry (RKE) transmitter twice. See Remote Keyless Entry (RKE) System Operation .

On vehicles with a liftglass, press the button on the underside of the license pocket applique (A) to open it. The liftglass can also be opened by pressing the liftglass release button on the RKE.

To open the entire liftgate, press the power liftgate release button on the RKE or in the vehicle. See Power Liftgate . You can also press the touchpad on the underside of the liftgate handle (B). The liftgate will open after a slight delay. The vehicle must be in PARK (P) to open the liftgate. To close the liftgate, use the pull cup or pull strap as an aid.

The liftgate or liftglass cannot be opened if the rear wipers are in motion. Attempting to open the liftgate or liftglass while the rear wipers are in motion will cause the release of the liftglass or liftgate to delay until the wipers are parked off the liftglass.

Both the liftglass and liftgate have an electric latch. If the battery is disconnected or has low voltage, the liftglass and liftgate will not open. The liftglass and liftgate will resume operation when the battery is reconnected and charged.

If the battery is properly connected and has adequate voltage, and the liftgate or liftglass still will not function, your vehicle should be taken to a dealership for service.
