Drivers door popping open when driving

Post by Ciaraneng »

I'm having a problem with the door popping open at inopportune times when going over small bumps in the road. I'll eventually hit an oncoming vehicle if I don't get it fixed. Has anyone else experienced this and if so, what was the fix? Are replacement latch mechanisms available for T25's? Mine is an '83.

Thanks David. I tried lubricating the latch but if anything it made the problem worse.

I’m guessing that a spring in the catch mechanism has likely broken, and so locking latch is not positively engaging when the door closes and is working itself open in transit from the vibration. I don’t think these catches are available as new parts so I would suggest you look for a good secondhand example and try swapping it out.

Thanks clift_d. I'll try to find an old one.

David, have you any interest in selling one of yours?

I tool the latch mechanism off. It needed a good clean after many years of use. This took some time. Here are the before and after shots.

Here’s where it came from:

I stretched the longer piece, cleaned out the channel it was in and reinstalled it (not easy to get out or in).

The latching mechanism is working much better now so hopefully it will last until I can find a new latch or a spring.

Hi Aidan. The reinstalled latch seems to be working fine so don’t go to any trouble. If it hangs in there I won’t bother changing it out.

Thanks, Ciaran.

It’s your decision, but I wouldn’t take any chances if it were me, i.e. I’d look for a replacement. The integrity of the impact protection to the cab relies on the stiffness of the doors transferring the force of the collision back into the rest of the body shell, which they wouldn’t be able to do if they pop open on impact for any reason.
