Last year I sorted all of the door and window problems on my Cerb and they've been fine for agaes... Until now!

Passenger door won't open from inside.
Drivers door won't open from outside.
Drivers window won't open/close 2 inches when opening/closing door (it's stuck at the 2 inch down position.
Drivers window won't auto close when locking door!


I don't have my wiring diagrams here so does anyone know of one common thing for the above problems? I need to get the window shut before the rain comes! frown

Locking the car and opening with the fob should close the windows fingers crossed.

That's the problem, the drivers window doesn't react to the fob at all since this morning!

The only cure for these problems I've found lives about 8 miles from you.

Try fuse 7 as that effects the doors?

I know, but I'm an electronics engineer so should be able to do it myself. Not so easy when I haven't got the wiring info to hand frown

Logic says that there is a common denominator for all these symptoms! Mind you, is is very little that is logical about TVR wiring!smile

Have you tried unplugging the door/window control box for a few minutes? Might need to stick a finger in your ear and hop about while singing the Top Gear theme tune, although this only worked once for me smile

Strange thing... Last year, when I had some other problems, just unplugging one of the connectors on the box had the effect of making both windows wind up to the top. Doesn't happen now! frown

Anyway, I've armed myself with an allen key, emery cloth, contact cleaner, silicon grease and a DVM and am heading down to the car park!

Had similar issue the other week; outer door button stopped working but inner door button worked.

Inner and outer door buttons on seperate circuit. The problem with mine was the multiplug in the door, usual corrosion due to water ingress. Sprayed with wd40 and been fine since. You could also spray the multiplugs going into the door control box

Use amagnwt on the reed switch on the drivers door to confirm if that is the windows issue.

The switches will more than likely be the multiway connectors inside the doors.

All sorted! Quite simple yet quite confusing!

Passenger door inside switch... Corroded connector, both male and female pins corroded right through!
Drivers door outside switch... Corroded connector, one pin in the connector corroded right through!
Drivers window... Reed switch sensor connector corrosion, cleaned with contact cleaner. I assume that the system decided the door was open so would not let window go right to the top!

The strange thing is that all three failed at about the same time??!! confused

I've jury-rigged it for now. Will get some plastic mil-spec connectors tomorrow, that'll prevent any recuurence of the problem! smile


Thanks for the input guys!

Karl had similar & was as you, I found a small lagoon at the bottom
of the door, managed to hook the loom leading to the reed switch & all other wire's & attach them to the middle door bar. Should help stop the water ingress.

I'd already lifted the wires and cleared the drain holes last year. This must have been water on it's way down or vapour. The new connectors will be totally sealed! smile

Replace the door connectors with proper waterproof AMP Superseal ones and end your door and window problems forever! One of the best jobs I ever did on mine.
