Hi all, new to the forum and have been tasked with looking after my girlfriends mini cooper (2001).
When we bought the car the central locking or passenger handle did not work, and the boot would not lock. I think that the previous owner disconnected the outer handle on the passenger side so you could not open from the outside, and then locked the drivers side manually with the key. All fine but it failed the M.O.T. on the passenger door handle and the boot has no way of locking. So.......went to a mini breakers who fitted two second hand door lock actuators.
Re-connected the battery, and all good. Car will lock and unlock. I pay the money and drive off. As soon as i get home i lock the car with the fob, and the locks go down and then straight back up again. I thought, ah i have read lots of this, and just bit the bullet and bought 2 Brand new door lock actuators from mini. I have just finished fitting them, reconected the battery and all working perfect with the fob and toggle. Get in the car and turn the ignition on, get out, try to lock it with the fob......AAARRRGHHHH same again, it locks then unlocks straight away. I really do not know what to try next.
So in summary. If i disconnect the battery and then reconnect the central locking will work fine. As soon as the car ignition is turned on / car starts, locks work with toggle switch perfect. Turn off ignition and leave car and as soon as you lock it, it unlocks itself. The only thing i have noticed is that after i connect the battery the windows dont seem to drop until i put ignition on, then i can drop them with the switches and normal service is resumed. Also at somepoint it looks to have had an aftermarket alarm fitted (it came as standard with no alarm) but when i purchased the car this had been deactivated. I am at a total loss and after throwing £400 at it with second hand / and new actuators i dont know where to turn next. It just seems odd that after a battery reset it all works fine, then as soon as the car starts it reverts to locking/unlocking dance
Any help greatly appreciated
