I have a 2000 buick park ave that the trunk keeps popping up upon sitting or when opening any door etc
the trunk will pop up at different times like when any doors opens or just after sitting
not being driven, also the blend door for heater and air not working properly. i have replaced all the blend door actuators to no avail.
I have the same issue: but only after the "5 minute" delay time after turning off the engine. Open a door and the trunk pops open. Ken
