I am having a problem with the FLAPS on the Boot Lid. Drivers side does not return when roof is closing. Have to manually push it back into the lid before the closure can complete.
No problem the other way when opening. The Flap seems to have some sort of ratchet positions which I can hear when pushing the flap back. Is there some sort of adjustment to this. Thanks
