TobyPick Posted September 16, 2018 Share Posted September 16, 2018 Hello, I have a Ford Fiesta Zetec 2007 (MK5) with 3 Doors. I have an issue with the passenger door shutting but showing on the dashboard as being open. It often must be slammed repeatedly in order for the car to lock properly, as the car thinks the door is open and automatically unlocks it. Sometimes while driving, the dashboard will suddenly show the door as being open, usually after going round a sharp bend. I have lubricated the latch mechanism thoroughly, but the fault still occurs. I have accessed the GEM unit below the steering wheel but there are no wires that are obviously loose/damaged. Another forum thread explained that cutting a wire and terminating it to ground/earth cures the fault as the sensor will always assume the door is shut. Can anyone confirm exactly which wire to cut and attach to ground/earth? Quote Link to comment Share on other sites More sharing options...
Luke4efc Posted September 16, 2018 Share Posted September 16, 2018 Don't start cutting and grounding earths. It just makes it a real bodge job. By the sounds of it your loose or damaged wire is in the door sensor somewhere as you're having to slam it shut for it to acknowledge. I'd take the door card off and have a look there first. Another common place for wires to split is the loom going from the body into the door so might be worth checking there for anything obvious.

Appreciate the reply, but thats not really answering my question. Quote Link to comment Share on other sites More sharing options...
