Hi

Have a really strange one...both electric front windows have stopped working. checked the 30amp fuse all good

Whats strange is with the drivers door open, car running, if you press either of the door window down switches on the drivers door or the passenger door down switch, the car attempts to unlock the doors, you can hear the solenoid in the rear drivers side door activate

Any ideas, going to take door card off and test switches, but suspect either a wiring short, relay or door module failure, anybody had a similar problem ?

 

 

 

Cheers

 

 

Hi Jon,

Did you fix this problem as I'm currently having the same problem.

I've got a 2003 Fiesta and it's been happening since last week, though it did briefly fix itself which seems to lend itself to either a short or perhaps a faulty switch. In addition locking the car from the drivers side only locks the drivers door and from the passager side it sounds like it locks and immediately unlocks all doors (or at least the two on that side of the car). With the drivers door shut and ignition on, locking the drivers door from inside causes the open door light to appear on the dash. I've had an issue with the open door light appearing intermitttently for several months and figured it was the door open microswitch in either of the RH doors or the boot as they are the only ones I have had open prior to the fault but haven't had any locking or window issues until now.

I hope you're still around and can point me towards the solution you hopefully came to.

 

Best regards

Kevin

Unlikely....

On the facelift models, doors refusing to lock may be a front door microswitch indicating that a door is still open.  Doors normally lock if a rear door is "open".

Door locks are controlled by the GEM, but windows are switches and motors, so if there is an interaction between windows and doorlocks, probably a wiring problem.  I would start by disconnecting the battery, then having a look at the door connectors in the "A post", undo them and make sure contacts are clean.  After 20 years of flexing, the cores going to those connectors from the door might well be shorting together.

Hi guys, has any of you fixed this problem? Just bought a fiesta with the same issue; pressing any window switch (both driver and passenger side) triggers the central locking. Also touching the mirror adjuster activates the central locking. The interior light seems to go on as well when pressing the window switch.

My key didn't use to lock/unlock. I changed a couple fuses and now it will lock, but won't unlock.

Also, the electric windows don't work.

Most probably the GEM has serious water ingress. Do you have any other problems, for example the wipers or screen wash ?

I also have the problem that the rear lights seen to work whenever they want. Already changed all bulbs etc.

If the GEM is the issue, what would you recommend? Changing the whole unit?

Yes you will need to replace it with the exact same part, although the very last letter of the part can be the same or higher.

You will also need to reprogramme the replacement with you cars "AsBuilt" data file using FORScan.

I understand. Changing the GEM has nothing to do with the keys and locks, right?

As I am not a mechanic, I do not have FORScan. You think I could find a download and pull this off myself?

Next post down are all the download links you will need.

Since you are going to need to programme the GEM you will need the Windows Laptop version with the full licence. This is normally £12 but because it is a Russian programme they are blocked from receiving payment at the moment. However you can still download it, and when you are ready to programme you can activate the free 2 months trial which is still working.

Yes you will need to reprogramme the keys, both for the remote lock/unlock of the keyfob and separately you will need to reprogramme the PATS immobiliser part of the Key. The PATS part will need TWO working keys, it does not matter if one of them is just a standard key, so long as both of them can start the engine now.

You will need to buy the vLinker FS cable (Amazon link below).

I'm sure that we can probably talk you through the process. You will also need some switch contact cleaner because I suspect that when you unplug the GEM the connector pins will be green and corroded.

Well to be fair, I disconnected the GEM and it looks super clean in contrary to the rest of the car. I'll attach some pics.

OH !!!

That's the best looking GEM I've seen in a long time. Which makes me worry that it might not be the cause of your problems.

Having said that, just because it looks good doesn't mean that it isn't faulty. I'm not too sure what to say, all your faults/problems point at the GEM being the cause. You should still go ahead and get FORScan and then you can run some tests on it and check for any DTC's before deciding to replace it.

Thanks for your suggestions. Will take a night to think about what's best, appreciate your help a lot!
