Central locking Problems on Chimaera
Discussion
Guys, Your help please, Whilst driving along the central locking trips and the relays / solenoids in the doors chatter. In the past I fixed this by re installing the door pads for the courtesy light switches, this time however this isn't the problem. ( I've even taken the switches out completely and the problem remains) has anyone seen this before?
I can only suspect the central locking relay or a dodgy earth connection somewhere, I believe the relay is under the dash pod , but where do the relays/solenoids go to earth?
The car locks and unlocks find whilst staionary , it's just whilst on the move. Help!!!!!!!!!

Keep the ideas coming guys, thanks for the responses so far, as you can see I've tried all the usual routes but completely stumped by this. It's difficult to recreate whilst stationary aswell.
Any ideas on where the earth is for the door switches/locks etc? or can i disconnect an alarm wire to prove a point? if so which one?
thanks

ribol said: I think a good place to start would be to find out exactly what does happen when you are driving along. Is it always trying to lock the car or is it always trying to unlock an unlocked car and can it actually do so on its own? Or is just pulsing the solenoids and getting neither done? I think this would definitely get you nearer to solving the problem. If it always locks unlocked doors for instance then its very unlikely we are talking about an earthing problem.

OK, if doors are closed and locked from inside, whilst driving along doors will unlock ( don't open) and door motors start chattering. If the doors are closed but unlocked they will not lock, but will start chattering. ie the same symptoms as missing pads on the doors which was my first guess, but even with the switches removed to simulate doors closed, the problem occurs. Also the car is a 95 model with chrome buttons behind the doors ( no key lock)
thanks

I would try disconnecting the door connectors to the lock solenoids. If it stops; then conect 1 at a time to find which lock is shorting.
This should be quick & easy diagnosis, compared to accessing dashboard cover.

I've now disconnected both door solenoids and door switches but the problem remains ( I can hear the relay tripping under the dash, , curiously it appears to be worse when the car's hot.
Next step is to lift the dash I suspect.
OK, I think I have narrowed this down to the cetral locking relay ( all other parts have been disconnected at one stage of another but the problem remains.)
After taking the cover off the relay it feels as if one of the two solenoids isn't holding away from the contacts as it should. So a new relay it is.
Can I get this parts from anywhere else than a TVR dealer, they want £44, similar on the web is £8, I'm all for originality but that's ridiculous.
Any suggestions on where else I could get this part?
thanks
