Transit connect side door wont lock.
If your drivers side door won t open try spraying some wd 40 into the area where the door connects with the lock inside the car.
I assume you still have the manual unlock lock turn knob at the inside back of the door opposite end to the handle if so when you turn it clockwise about an 8th of a turn the mechanism should unlock however if it dosent go round with a sharp click try pulling rattling the door handle as you apply force to the knob and the mechanism may spring into place if your lucky had several successfull openings like this.
Try opening the rear door driver side and operate the inside handle.
This will lubricate the lock.
Then lock it all up as normal.
In my case i could have probably unhooked the yellow.
The first thing to check is to make sure that any side door roller hasn t collapsed it is usually the middle roller that goes this results in the door dropping enough so that the contact pins for the locking motor that connect the wiring from the body to the door don t align any more.
This happened on a 10 plate transit last year more than once.
Ok i suspect the reason the door latch won t lock us that the bcmii thinks the door is still open can you give me the reg number so i can clarify the wiring details regards brian.
I had to take out the lock to repair and decided to show whats happening when rotary knob gets stuck.
