Hi Guys,

 

Was wondering if anyone was able to offer some advice as I don't know where to begin with an issue I'm currently experiencing with my 2012 Titanium Business Edition.

 

About the end of 2018, I noticed that it was experiencing an issue where I would lose the ability temporarily to control the passenger side windows/wing mirror but after a bit of a run they would all reset during a trip. I noticed that on occasion if they hadn't reset themselves, the car would not lock properly, mainly with the drivers side doors. It mainly happened on cold days, but as it was very intermittent I never persued it.

 

Then about 2 weeks ago, it started acting up badly and not fixing itself, same issue and I'm now looking to fix, but not entirely sure where I should start.

 

The drivers door no longer locks under central locking, and this is accompanied by the drivers side rear door, but the passenger side locks fine and the alarm does engage. I've been locking the drivers side doors manually. But the drivers side doors do open when I unlock the car intermittently. The passenger side door locks seem to operate consistently.

 

When the car is running, I only seem to be able to control the drivers window and this occassion cuts out so it does not work at all when the window is either fully open or closed, but cuts back in randomly. I find that turning the ignition off, opening and closing the door then starting the car back up seems to get this to work again.

 

The other windows all operate from their individual window switches and the automatic opening/closing works on them unlike the drivers door. In addition to this, neither mirrors now respond to the mirror control or fold in when the button is pressed or the car is locked.

 

The drivers door console for the windows etc, still has all of its lights working.

 

I've done a bit of reading and can only conclude its the Drivers Door Control Module, but not sure if this is definitely the case and was wondering if anyone else had similar issues or could maybe point me in the right direction of what to check. I'm not the biggest car buff, but I have a basic understanding of how these things work.

 

Is this all one issue or is coincidentally two or more separate issues?

 

If you need more info, please let me know!

 

Any assistance or advice you can offer would be massively appreciated.

 

Hope you are all staying safe!

Any assistance anyone can give would be massively appreciated!

Hi

 

This may not solve problem but first item I would check is plug/socket at door post. Check if they are fully engaged and sealed with no ingress of water to corrode terminals.

Battery / Alternator test maybe worthwhile also.  http://www.talkford....test-procedure/

Hi I think Peter is bang on the money, most of the weird and wonderful things I had happen to me over many years  of running these vehicles was the little run of cables between the doors although they are well shielded both ends the only conclusion I could reach was that as the car got older and the constant opening and shutting of the doors especially the drivers door, the integrity of the rubber boot becomes compromised.

Give the connector pins a good hose down with electrical cleaner and finally a little spray over with white grease that slows it up, I even had it with both rear passenger doors, things like the windows opening on their own, or not shutting properly, especially disturbing when you have paying passengers in the back, all corrosion based faults.

So just to give an update,

 

I took the door panel off today, and checked the connectors, nothing untoward seen.

 

On a hunch I plugged the connector back into the door control panel and it all started working. After closing the door, it stopped again so I gently pulled back the wire sheath going between the main chassis and the door as it was crimping towards where the door opens to and so far everything seems to be working!

 

I'm pretty certain that is the point where the failure is occuring so will arrange for an electrician to take a look at some point but am over the moon its back up and running. Quite satisfying hearing the central all lock back in again. Total Cost was a tenner and that was only because I didn't have Torx bits (Needed some new screwdrivers anyway so nothing lossed nothing gained)!

 

Cheers for the advice again all..

 

One last question, anyone know what size battery the Mk4 can accomodate? I'm seeing a lot of 278mm lengths mentioned in specs but I can't find an 80ah battery at that length. Am due to change the battery soon and dont want to use less then 80ah if need be as the original ford silver one thats in there still is also 80ah. Any ideas?

 

Cheers again!

Thanks Purple,

 

Was this with the battery cover still on or would that have to be removed?
