help door brocken

My local garage doesnt know how to fix the sliding door {it doesnt stay shut} does anybody know anyone within a reasonable distance of cambridge that might be able to fix it.

I'm way too far away being in cheshire.

But the door locking mechanism is a very simple setup that any half witted bodger should be able to solve.

I would start by taking the door card off, removing the locking mechanism at the rear edge of the door and test it catches ok.

Try lubing the lock? Is it the back of the door popping open?

no its the front that pops open , it doesnt locate at the front

Sounds a bit of a daft question but has your door got the two locating tounges and plates held on with 10 mm headed bolts on the door and door pillar.??
Have a look at the other door to see if they are in place on that door as that one is presumably staying shut.

The location tounges and plates seem to be in place , the door goes into place but doesnt stay

So how is it then that the front pops open!!

The doors pop out at the rear first.

That's what I can't make out so that's why I asked about the locating plates at the front.

How about posting a few pictures of the leading edge at the front of the door and the door post and how far the door pops out and wheter it is top or bottom that pops out furthest or first .Have you checked the condition of the upper door roller guide/track.? And check the condition of the two wheels on the top of the sliding arm and the lower sliding runner wheels on the bottom of the door. Take pictures of all those and post them on here for all to see and hopefully someone will spot the problem.

My money is on the upper guide adjustment where it fits to the door.

piaggio05 where in cambridge are you?
I work on Coldhams Lane & if you want to pop over one day this week/wednesday or friday i can take a look. i cant fix it but i can see what might be going wrong for this lot to help with.. + you can compare mine to yours to see whats missing...

That would be very use full thanks , the garage has managed to sort it out but its not perfect and the other door falls of the runners , but as long as I can use one door I will not use the other one for now.
I could pop over Wed morning or Friday afternoon.
Many Thanks

I can only do afternoons after I finish work.
Wednesday I finish at 3.15pm Friday at 2.15pm
PM me for the address.

been meaning to post but kept forgetting! my passenger side sliding door pops out at the front too, i put it down to the rollers needing replacing, the whole door is a bit grindy when i open and close and i have to be careful it doesn't fall off the runners, did adjust it as much as i could but haven't got round to sorting it properly yet!

I fixed one a couple of weeks ago for a lad of this forum, I had to bend the runner back to some sort of normal shape, replace the bearings, and do some serious adjustment. Took a good hour of faffing about with it.

I dont think mine will ever be right ,the door runners are to damaged for a start, but at least it stays shut ,although there is still a small gap , I want to use the van for sleeping in and thinking i will have to use the back door and put a handle on it to close it, I will cut some sort of hole in the door card to access the cable to open the door.

thats exacly what i was planning :-) i do use the sliding door when i camp but it can be a pain and the drivers side one is siliconed shut so no idea what thats like

If you get a gap when closed the lugs (tongues and receivers) on the front edge of the door probably are not setup correctly.

ill have a look, its only a small gap at the top now
