Discovery 300tdi door locks.

Hi guys and girls, I know this is an old chestnut but it is driving me nuts. I have a 1997 disco 300tdi. The passenger side front and rear doors do not open. It is as if the button just doesn't rise high enough. If I pull the button up manually just a mm or two the handles work fine. I had the door cards off to adjust the threaded link rod that connects to the exterior handles a couple of turns to give them extra pull but I could not find any adjustment for the mechanism itself. I also lubricated the actuator mechanism to see if that was the problem. There are a lot of threads on here about replacing springs, is this a route I should go down? When I tried to remove the top window frame to get the lock mechanism out I also rounded off the torque bolt on the outside of the door at the top on the front door just to make it more interesting. Any advice on how to remove that would be great for starters, lol. Or can the lock be removed without removing the frame? Also, would it be adviseable to cut out a small access panel on the inside of the door beside the lock to get easier access to the mechanism itself?

I need to fix the boot door mechanism also but I might leave that for another day. It doesn't lock with the central locking. The button just springs back up again.

Any help or advice would be most appreciated.

Thanks, John.

the door locking pins which connect the lock is self,the central locking motor and the door pin ,are joined to the lock part by a rod,this stretches over time , it can be adjusted,look around on here theres a how to!

Cheers dolly disco, I have ordered a new spring set so I will set to work this weekend, thanks for the quick response to the other posts as well. Newbies are great !!!!!!.

John

fixed?

Sorry for the delay in updating, the springs took a while to arrive as the company I bought them off on ebay went on holiday for a week. Also had some trouble removing the bolt that holds the window frame. Got that sorted now and the springs came so will have a bash this weekend.

Cheers,

John
