My hatch lock doesn't work, pulled the rubber grommet off between hatch and body and found the yellow hose broke. Problem I have is refitting the rubber grommet to the plastic insert in the hatch and body. Can you buy the plastic inserts, or does anyone know what they are called? Ended up pulling the plastic insert out of the body, fitting the rubber to it and pushing the insert back into the body. Am worried if the seal is good, don't water getting into the body. Any help would be appreciated.
