Electrical failure, locking + RH side doors

Featured Replies

I have a diesel 1.9 4x4. I let my battery go flat. Everything was dead. I opened the driver's door with the key, no problem, then lifted the bonnet. I connected spare battery with jump leads. Alarm sounded. Silenced it by turning on ignition. Started car, no problem. ESP (anti skid) and power steering lights came up. I disconnected jump leads and ran engine for ten minutes at fast idle. Switched off and restarted, no problem. ESP and power steering lights stayed on. Drove a few yards and ESP and power steering lights went off. All seemed okay.

THEN, later in the day, I realised other things had failed. I can't open the rear offside door at all, either from keyfob remote or from inside. The central locking button on the centre console is dead. The keyfob won't unlock or lock the driver's door, only the nearside doors and boot. Also, driver's side windows don't open. Nearside windows open with their own controls, but not the 'master' controls on the driver's door. When I start the engine there is a 'clunk' from the nearside and boot locks, but I haven't yet worked out if they are unlocking or locking themselves or just making a 'clunk' noise.

AND... mirror adjuster / heater controls on driver's door won't operate either mirror.

AND... rear-facing red 'door-open' warning light on driver's door doesn't light up.

In short, the offside doors are electrically dead. Any ideas?

Try disconnecting the battery negative terminal for a few minutes. Otherwise it will be a fault code read and expense.

FordFan, thanks for that. I'm away until the weekend (the car still drives okay) and I'll try your suggestion when I get back - don't want to risk making anything worse before this trip! Also, it's minus six outside so I'm not that keen on doing it today. Will let you know how I get on.

FordFan, unfortunately disconnecting the battery didn't work and everything is the same. Looks like a costly garage fix!

Thanks, TT

All the items you say are not working are all controlled by the electronics box which is an integral part of the Driver's Window Motor.

When these go wrong, they sometimes cause excessive current drain, which may have caused the flat battery in the first place.

Electronics box replaced under warranty, everything now works!
