Forgive my ignorance but what is a module and where is it located on the vehicle. I have been qouted £90 for a diognostic check and then £90 per hour labour plus parts to rectify the problem . I have had no previous problems with the liftgate and it occurred after the wife closed the lid after loading shopping . As you stated its not easy to get to the interior but there is what appears to be an inspection plug at the location of the lock prehaps some dw40 might help its just so darn difficult to get to .
Thank you for your swift reply They say that trouble comes in threes well i'm also experiencing trouble with the drivers window which lowers very slowly ( if at all ) and the passenger electric mirror which when operated from the mirror switch doesent lock halfway but goes to its full extent .do.you think the problems are related ?.
These problems would be separate from the liftgate issue. the window problem is most likely a weak window motor, the mirror problem is going to be the mirror or the switch itself.
