Xantia Estate Tailgate Lock

Post by NAM »

Can anyone help? I have had an intermittent rear tailgate lock working and not working :cry: - ususally sorted by repeated locking and unlocking. Today it stuck in the locked position and I managed to unlock after crawling in the back and prising off the plastic bit (advice elsewhere on the forum).

OK - so I pressed on, removed the trim and membrane to reveal the motor and mechanism. The motor seems to be working fine - moving in and out but the actual mechanism - bit of a complicated looking system of rods doesn't seem to be working :( .

I have applied plenty of WD40 and will recommence activities in the morning.

Has anyone had similar - is there something I need to do or are we looking at a new lock/rod part?

Any help and comments greatly appreciated.

Not solved the problem, but found it a VERY common problem!

I did free a customers off with WD 40, but the solinoids are a weakness, and use the old style solinoid from the 309 / BX days..

The same problem happens with XM's tailgate locks, in the same way!

Other then WD40, cannot sugest anything else, but just share the same experiance.

I had recently same problem which was solved with a "new" lock motor from a scrap car :)
Here's link to my --> Tailgate lock problem.

It's good that you found out how to open it from inside the car.
Read CitroJim's reply in above thread which explains the mechanism function in detail 8-) .

When I got the replacement lock working I have opened the old lock to see how it works. It's heat welded (ultrasonic welding I guess) and it's not meant to be opened.

PS: Make sure that the plastic membrane is sealed well, especially from lower part, near rods.

Next moring and two and a half hours later - the car has nice aroma of WD40 and after much looking, checking, moving stike plate and generally messing about...............it WORKS!

The bit that really needed checking and adjusting was a really small part near to the bit that grabs to the bar and locks the tailgate. The part is a screw adjusted plastic "clip" which allows a metal rod to meet with the lock. When you get to grips with the mechanism it really is a bit of a dogs breakfast - I never cease to be amazed at how things are designed.

It is a bit tricky to explain but my advice is to get to grips with how the lock works - use plenty of WD40 and keep messing about!

Now for some breakfast!

A source of inexpensive door lock motors is Maplin. As far as I remember they fit the Xantia Estate tailgate despite at first sight looking different, There is also kit which gives you 4 motors for £25 or so.

Is this http://www.maplin.co.uk/module.aspx?Tab ... &U=Strat15 the motor from Maplin that fits? If so would I need the 2 wire or 5 wire for my Mk1 Estate?

Thanks

The Two Wire ones Richard. The wiring is very simple, straught to the motor in the lock. The ECU reverses the polarity to effect the lock/unlock action.

These motors look just the job and are excellent value...

As Jim says, the two wire type. Again, as far as I remember, the 5 wire type is a two wire motor with an internal changeover switch so that front doors can operate the central locking. You could leave this unconnected if replacing a two wire.

Note that cars after about 2000 may use totally different door locking systems.
