Hi central locking been temperamental so took the vacuum pump apart and cleaned it, now the locking works but only seems to lock the front doors and the fuel cap, i noticed before that the front two doors locked but the rears took a lot longer to move the buttons.
If you maually push down the rear door buttons and lock the boot the remote operates and unlocks all the locks as it should.
It seems like there is not enough pressure to lock the rear doors although if i push the button down slighty the door seems to lock.
When i push the buttons down manually the rears seem very stiff compared to the front so am thinking about removing the panels to see if i can lubricate the linkage, any help would be appreciated.
Regards Mark
