I can see others in the past had problems with the doors, but not quite like this. Can anyone help?

The battery on my cerb. died. After replacing it I can't open the doors and the boot switch is not working.
I have access to the boot smile and I have checked all fuses - they are ok. I have unpluged all plugs on the door control unit and reconnected them, but the doors will not open.

I don't think it is the switches as it would be strange that both door switch and the boot switch failed at the same time.

Any suggestion how to fix this ?

I tried to pull the release for the door but it won't move at all. Do I have to do anything before I release the door manually?

Sounds obvious but are you sure that you have reconnected all of the leads to the battery and the battery is charged? Does the alarm work/indicators flash?

Jep, it is a new fully charged battery. The alarm work and buzzer are working and I the red led in the rear windows turns on/off ?

The indicators do not flash when using the remote, but I can't remember if they use to or not?

I noticed another odd thing when I was checking the fuses. When I remove fuse no. 7 then the head beam switchs on. When fitting the fuse again the ligth truns off again. Is that normal? confused

The situation has gone from bad to worse. While pulling the ceased emergency release, then the cable brok banghead -now there is no mechanical way into the cabin.

I can only think of two solutions:

1) tricker the electric door release from the controlbox in the boot
2) lowering one of the windows from the control box in the boot.

Would anyone out there know how to do that?

Other suggestions are very welcome wavey


I feel a bit tumbleweed and I really hope you can help me or may be point me in the direction of someone how can. The car is abroad and with no access to the cabin it is difficult to get the car to a TVR garage.

The indicators should work with the remote so it's possible it might be alarm/immobilser related. You could try disconnecting the battery, wait a while and connecting it again.

I seem to recall there was a reset procedure for the alarm/immobilser, never had to use it myself, but IIRC it involved depressing the keyfob for some seconds, could be wrong, perhaps someone else knows?

Checked again and the indicator light is flashing as it should when arming/dis-arming the alarm.

However, to make sure that I don't leave out any posibilities I still disconnected the 12v batt and held down the remote control button when reconnecting the battery.

The door and boot switchs still doesn't work cry

I guess I'm back to plan 1) or 2). Do any of you know how to connect the wires in the boot to bypass the door release or lowering the windows?

Page 22 for the door module.

Disclaimer... I haven't tested this, so solely using the diagram... connector 3 appears to be your lock outputs.

Page 23 suggests you need to put a voltage across pin B2 and pin B3. Presumably reversing the voltage for either lock or unlock.

Be conscious of the fact that doing that alone, won't drop the windows. But if you're carefull, I believe the glass should gently pass the A post outer trim.



Edit, if you want to drop the window first, it appears to be connector 4.... looks like a voltage across A2 and B1

Hi Russel

thanks a lot for your response.

I tried to apply a voltage across B2 and B3 (both ways) but nothing happened,

How do you suggest that I can test the door lock?

Do you know following is connect to the plugs into the box?

Was it definitely connector 3, you tried ? Wires should be Blue/Green and Blue/Orange, according to that link.

That diagram you posted, appears to show the window 'inputs'. I'd be inclined to forget about triggering inputs, in case the module is knackered, or hasn't got it's supply voltage.

I'd be more inclined to concentrate on sending a voltage down the output wires.

I'M IN !!!!!!!!!!!

Thanks a million Russel you are a true star.

I lowered the window, and when I pressed the door switch from inside the door opened.

Now I have to find out why the out site switches are not working.

Nice one thumbup

Looking at that connector 1, it's strange that the inner door buttons are working, but not the outer.

I notice the window inputs are on the same connector. Are they going up and down, off their buttons ?

If so, then it's as if you've got that little button on the centre console pressed... the one that deactivates the outer buttons confused

Edit... Just noticed that the outer door buttons and boot release, are on terminals A6, A7 and A8 of that connector 1.
Has the connector definitely gone back in to the module ok ? It's not at a slight angle ?

Something simple like the outdoor switch failed? Wire off?

Both doors and the boot, by the sounds of it.

Russel none of the external switches was working.

I have now started the car up and suddenly are the external door switches working.

The boot still doesn't work.

I think I might have located the error. When moving the gear lever the driver door suddenly open. I can repeat the fault and I think that a doorlock wire may be damaged under the center console.

Do you know how to take the leather topcover off the center console?

I'm looking forward to how you figure this out, it's a job that I've often wondered how complex it would be - but fortunately, I have no need to do it hehe
