Hello all, I am getting really frustrated so hoping you can help.
What was an intemmittent problem is near enough all the time now. When I lock the drivers door with the key (The alarm is inoperative - maybe linked) it immediately unlocks and performs a full open (Windows down etc). As per usual it works fine off the central locking button in the centre console 100%. It is now so prevelant that I resort to a 10mm spanner in the boot to disconnect the battery when it refuses to shut...
I have googled to death and read up on a few things to try and had no luck so far, I have checked all fuses (I know of) and I have tried changing:-
1. Ignition Switch.
2. Fuel flap actuator/solenoid.
3. GMIII Module
Everything works fine apart from the alarm and the central locking. On reading the codes a fault was diagnosed with the Drivers door lock solenoid however replacing that with a known good one made no difference so reverted back.
Only other thing I can think of is the drivers door module - I cannot even find the part no on realoem for that, only the passenger side and I believe it will require coding.
Anyone got any ideas or info on the drivers door module - this thing is driving me nuts.
Thanks in advance for any help....
