Busted the Cerb out for the first time in a while today.. Was going fine till I pulled up and went to get out and the doors wouldn't open on the buttons. Windows were not working either. Used the emergency levers, and the doors/windows came back to life.

The window buttons had been a little hit and miss for a while, but I thought it was the buttons..

Now the doors and windows are completely dead, and interior lights don't come on. The windows raised themselves up at some point and have stayed there.

Tried the disconnect the module trick with no luck.. Could this be reed switch failure? The passenger's door has been a bit temperamental for raising/lowering for a bit..

When the windows were playing up, if you held the button pressed for long enough, they would work, it was always up only.

The exterior door pop isolator switch is going a little haywire and the boot doesn't work either now.

If it was just the doors and windows working intermittently i would say check the connections in the doors by taking the door cards off.

The fact you said the boot has also stopped working would make me think you have a problem with the box itself possibly.

Get out your multi meter and start making a list of what works and what doesn't work. If you find out the switches are all working but the doors and windows don't then the box needs testing.

I will try and dig out one of my old posts with a simple guide on testing the door and window functions. You can also operate the window motors manualy very easily to get them lower so they don't catch on the a pillar trim.

I replaced the door connections whilst it was off the road..

The complete ans utter failure of everything door/window related did make me think control box.. Just not 100% what reed failure might show as.

Mine did this to me last year, unplugged the control box for a few seconds plugged it back in and all good ever since.

Check your fuses carefully. I had something similar and it turned out to be a fuse blown. If they are all ok then you are probably looking at a session with your head between the back seats, checking all the connections there and then tracing the feed for the door box with a multimeter.

Sounds like something the missus might be jealous of... laugh

Going to check fuses now as I tuck her up in the garage.

I am wondering if I have upset her somehow.. I let the missus have a drive yesterday?! Maybe that was it..

Anyway... Battery was flat.. Few cranks and then click click click. I then spotted the headlights were on by themselves (switched off, no rear lights on). Doors etc still dead. No fuses blown that I can see. Jump it off the daily, 13.9v showing at idle so it is charging, did 200 miles in it yesterday. Had to pull the headlight control box plug to turn the lights off.

Big fuse is new.

Anyone..? Seems like their may be a bigger issue? Or just a flat battery thing?

Mine is doing weird (albeit different) things at the moment, for example the hazards start flashing by themselves. Press the button and they flash brighter or dimmer. Tapping the box seems to shut it up. My battery has developed a large electron leak though and although the doors and windows open fine, it's not delivering enough power to crank the engine after maybe 8 or 9 hours from a decent drive. New battery is in the post!

Do you suspect your battery or do you suspect an electrical fault to be draining your battery?

I am suspecting an electrical fault.. I think. It started fine all day Sat. Whilst I haven't been using it, it is sat on a trickle charger maintaining the battery so that should be all good still.

I would consider a new battery first. Cerberas do odd things when batteries are on the way out. A new battery often solves many electronic gremlins. Then replace the big fuse - I once had odd electrical behavior and discovered the big fuse cover/box had opened and while the car was pared outside it had semi-filled with water and submerged the fuse. I dried it all out and then replaced the fuse and all was well again.

I think often replacing the battery works as you effectively reset all the control boxes at once.

If you still have problems after replacing the battery and the big fuse then you can start looking for a fault. I would do those things first though myself as it doesn't cost that much or take too much time to do.

When mine acting up it was a fuse which looked fine, also the battery had to charged to the absolute max or else mine I would have main beam on & hazards etc.
Just give it a good charge after checking fuse 7.

My big fuse is a brand new 125amp job. I did wonder if the headlights was a battery thing.. Will replace it and see what is still not working.

What flavour of battery is in favour currently?!

I went for a Bosch as it has very good cranking power and a 5 year guarantee. The only problem is the terminals are the wrong side - not that it causes any real issues it just means I would have to remove the top panel to disconnect it.

It seems to keep its charge very well too. I have left the car without connecting a conditioner for over two weeks and it still starts fine. That must be nearly a record for a Cerbera.

I've left mine with my new Yellow Top almost a month, no trickle charger - no problem at all. Highly recommend if no access to power for battery conditioner.

... and terminals the right way round!

I am not sure why people have batteries that go flat all the time, I leave mine weeks at a time and she still starts, a month parked on the drive is not uncommon.

All I can think is there is some underlying fault that needs sorting that I am lucky enough for my car not to exibit.

Oh yes the headlights thing, often happens on a cerb when the battery dies, a certain voltage is passed and the main beam headlights come on for a while. Mine does this every time I turn her off the light flash on for a second as the charging stops.
