Title: Doors keep locking on thier own
Post by g.wass on Apr 6^th, 2006, 1:16pm

To open the doors I have to put in the key and hols it in the open position to open the door. once I remove the key the door locks keep cycling until i shut the door at which time the doors lock themselves. This all happened from the battery going flat and being recharged
Also no interior lights or Radio and fuses OK
Scorpio 2.9 24v 1995

Tried disconnecting the battery for about an hour or so? Sometimes the car needs to be properly reset.

Look at fuse 36 it might just be the one if not the wiring diagrams are http://www.carsoft.ru/avtorepair/sierra_el.html otherwise it could be a faulty door module or even a wire that is shorting out in the door loom. but with the doors locking I would be looking at the door module if it was mine but others might have more idea.

Fuse 36 OK. All was OK till battery went flat. Only when battery charged this lot happened. No radio. No interior lights and doors lock by themselves

Go to this page and scroll down to 'Electrical Concerns'. I'd look at the battery saver relay Relay 16. If you charged up the battery wwhilst still on the car this MAY have affected it. Good luck.

Did you charge battery on car or was it disconnected?

Battery was charged on the car. Not by me but the previous owner. I have just bought the car knowing of the fault. Thought it would be simple repair.
Relay 16 OK but no voltage to it. Now what

Are you sure that fuse 36 is ok?. Fuse 8 is for the radio but fuse 24 covers the interior lights and 'audio'.Check those.

fuse 36 changed it 3 times just to be sure. can not understand why no voltage at relay 16. really could do with proper wiring diagram. being electrically trained do not want to call in auto trician but looking so much that way
thanks for all your replies by the way

Have you tried the link that Snoopy put up? that is the diagram for the Scorp.Despite what it says in the title ie Sierra.

Yes but no digrams of fuse box wiring . just refers to relay 16. it is just individual diagrams but the main loom diagram not there. Pity Haynes never did a manual

Relay 16 changed. Found fuse for radio and interior light blown so replaced, now have interior lights and radio. Only thing left giving grief is doors keep locking and unlocking when opened and lock as soon as doors closed. Any Ideas

Still having problems with doors locking by themselves.
Have changed fuses and relay 16. Have now chenged the door central locking control box. What else can make the doors behave like this????

Title: Re: Doors keep locking on thier own

The central locking module obviously detects that one of the FRONT doors are open and therfor will not lock.. Check the multin pin plugs that go into the front door pillars for connectivity and that there are NO shorts on them.
I had problems after I had disconnected one of the plugs some time back and it was all down to dirty pin connections.

Finally cured it. Changed the Central Control Module and now fine.
Thanks to all for help and advice
