Escudo Electrical problems

[paul187]

I have a 1992 4door escudo 1600 manual model.
First problem is that the door locks make the locking noise on there own while driving along but they do not acctully lock. This will happen at random.
After several weeks off this the seat belt light came on and the next day the wipers and squirters ceased to operate.

I have checked the wiper motor and squirter motors they are working fine.
I have also removed the drivers door lock switch but the random locking and unlocking is still happening.

Do these sytems operate throught the ECU / Computer? I have read several posts on this fourm pointing to faulty ECUs

Any help / advise would be apperciated
