My sliding door has been gradually getting worse over the last year, when I bought the van it was necessary to give the back of the door a little nudge when shutting to make it close, then recently i found that even when locked it was possible to open the door by moving the handle even slightly.
So tonight I thought I would take a look see at what was happening,
Firstly I checked that all the door runners where properly greased and that all the roller bearing where still intact and had not disintegrated, they where all fine so I applied lots of new grease, then i took the door panel of and checked the operation of the locking mechanism, again all seems fine, next I adjusted the striker bolt, I found that If I moved the bolt as far in ward as possible the door would shut great, and the shut lines where perfect, however the slightest touch on the handle even when locked would cause the door to open.
I noticed that the catch mechanism ( the brass hook shaped bit ) is only operating onto the first catch, if I remove the striker bolt and push it into the catch then it will operate onto the second catch, I am guessing that this is how it should work? but after refitting the striker bolt, irrespective of where I position the striker bolt I cant get the catch to operate onto the second latch. Even on the loosest setting the door wont operate the second latch of the catch, and this leaves a huge gap at the rear of the door.
So I am wondering if the catch is worn? or am I missing some adjustment somewhere? When I manually push the striker bolt into the catch onto the second latch then It stays there and doesnt 'pop' open again so the actual catch is holding .
Any help appreciated
