When the car came back from restoration in February 2017, Troy had got the central locking working perfectly fine.
All doors, hatch and petrol flap locks working as they should.
This lasted a few weeks.
I had scoffed at that time, because the central locking had been problematic for about ten years. Occasionally triggering the old alarm.
When I fitted a replacement alarm, I chose to omit the central locking wires.
Just to avoid further issues.
I have since fitted a Megamos remote locking module.
I have had the megamos fitted for a few weeks now.
My thoughts are that my issues are a wiring fault and possibly one dead actuator, not a module fault, because the same issues existed with all three types of central locking module when they were fitted.
1 - Standard Cavalier / Corsa Kiekert module.
2 - Vectra-B Kiekert remote central locking module.
3 - Vectra-B / Omega-B Megsmos remote central locking / anti-theft warning module.
I still have a lot of issues with my door locking motors, but I will get to the bottom of those eventually.
Findings are as follows: -
The driver's door works fine from the key in all locks and via the remote fob.
Front Passenger Door - faulty motor and / or wiring.?
The lock barrel micro-switch works fine and triggers the driver's door and hatch (lock and unlock). Not when driver's door is deadlocked.
When the front passenger door plunger is up, and the driver's door is locked via the key or remote, the driver's door and hatch locks will only lock briefly and unlock again, or will cycle between lock and unlock repeatedly until the central locking module "times out".
Unless I used the dead-lock on the driver's door key.
Rear doors are both dead - most likely broken wiring or corroded connector pins to the doors, or
Output wire from CDL plug? Unlikely as the passenger door lock and hatch lock do not operate the rear doors either.
All three doors ignore the driver's door plunger, motor and micro switches.
Rear hatch and petrol filler flap motors work perfectly from the driver's door plunger, motors and micro-switches.
I am sure that the hatch motor control output is a separate wire to that for the doors from the CDL connector.
The hatch switches will lock and unlock the driver's door and petrol filler flap, except when the driver's door is dead-locked.
So my thoughts are...
A - Faulty wiring from central locking 12 pin connector for lock, dead-lock and unlock of doors.
B- Faulty wiring to rear locking motors.
C - Faulty motor in front passenger door.
(Although I am certain that I tested a different used motor with no change in outcome). I have a third motor to test with if necessary.
Looks like a fun challenge.
It is probably a combination of at least two of the above...
