I have a 99 GMT Safari and the right side of the rear hatch fails to release when the release button is pressed. The left (driver) side releases and the right fails to release. It is an electronic release and the actuator appears to be firing as I can hear the same noise from both sides. With the hatch remaining in the closed position there does not appear to be a way to get to the mechanisms inside to diagnose the problem.
Anyone got any ideas?
Thanks Joe Connally
