My rear liftgate stays locked and wont open unless i manually open up the plug on the inside and flip the switch. the dealers telling me the part to replace it will cost roughly $300. i was wondering if anyone else has had this problem and how they dealth with it. also wondering if it is something as simple as a blown fuse or something, because in my opinion, the 'actuator' is not broken. any help is appreciated.
