Problem:Rear Hatch Inoperative with Rear Touch Pad
Model: 2006 Chevrolet HHR
The following diagnosis may be helpful if the vehicle exhibits symptom(s) described in this PI.
Rear hatch is inoperative with the rear touch pad.
First, make sure that the door lock switch or key fob UNLOCK button has been pressed 2 times. It is absolutely necessary to have all doors unlocked before the rear hatch will open from the touchpad. If still inoperative then remove the rear hatch panel, via the removable cover in the rear hatch inner panel at the bottom.
Unplug the actuator and install a test light in between terminals 1 and 3 of the actuator. Use the touch pad and watch for the testlight to illuminate for 1 second with every press of the touch pad. If light illuminates, replace the rear hatch actuator assembly.
Note: The NEW actuator/latch assembly will come with a long (1 foot) plastic strip hooked up to the manual release on the actuator assembly. This is to be removed from the latch before it is installed into the rear lift gate, as its for ease of production installing. (ONLY)
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
