Hi guys,i wondered if anyone could shed some light on a little door lock problem i have please? The car is a 328 e46 ci se 1999. I have read the manual on how to unlock the door via the remote. Press once to unlock,twice to unlock and have the window come down. However,when i press it once i hear all the correct clicking noises but the locking knob doesnt pop up. I have to then either manually put the key in to unlock it or press the unlock button twice to get the window to come down,then reach inside and unlock from within by pulling on the door open handle. I have tried all the key remotes so its not this. The passenger side also doesnt come up. In addition,if i press the lock all doors button by the hand brake,they lock down,but wont unlock up again. I have to again do it via the open door handle(pull once to unlock,then again to open door). Just wondered if it was something simple ive overlooked or have i a broken motor or loose locking mecanism? As i said,i can hear all the unlocking noises and the knob thingy moves slightly like it wants to come up,but doesnt. Many thanks.
