My hatch will lock the doors but not unlock them. And my doors will not lock or unlock the hatch. Any ideas? Thank you in advance to any and all suggestions. Glenn Back to top   Ads Advertising Sponsor Jeff Strickland Guest Posted: Sun Jun 22, 2008 9:19 am    Post subject: Re: Central locking problem / question All of the locks on the car are operated through a mechanical action when they are operated locally (with the key). The key turns the lock and the latch is locked or unlocked. The lock mechanism strikes a switch depending on which way you twist the key. By your description, your doors work properly -- the other door locks or unlocks, as the case may be. Operating the other locks remotely is an electrical action. The key turns the lock, which strikes a switch to operate the remaining locks. By your description, both doors will lock or unlock the other door but never operate the hatch, and the hatch will operate the doors for one operation but not the other. My guess is, the hatch solenoid is not working because neither door will operate the hatch lock, and the hatch lock has one of two switches with a sticky linkage that affects the switch operation. A malfunctioning hatch lock will cause the doors to lock but not unlock, or vice versa. And the malfunctioning solenoid in the hatch will cause the hatch lock to not respond to the door locks. All of your problems are in the hatch. "Glenn" <fake@faked.com> wrote in message news:fake-DDA90B.20553521062008@shawnews.cg.shawcable.net... Quote: I have a 1995 BMW 318Ti and I need advise.

Glenn Had similar problem on a Rover and it turned out to be a copper contact inside the lock itself that had got bent out of shape and would not register if the lock was "there" to be locked or opened or what the state was - open or locked. I simply bent it back and never had a problem with it for a further 3 years.

I can skin the hatch door myself and see if I can't "see" the problem or just change out the offending parts.

It looks like the answer is in my hatch and likely the locking mechanism. Cheers!

I took my driver side door lacth out because the window did not drop and raise properly, and found the defective switch. There are three switches on the door latches, my guess is there are two on the hatch latch. I'm not so interested in unlocking the doors from the trunk, but I like locking the doors from there, and unlocking the trunk from the door. One thing you might find is a broken wire in the bundle that passes between the body and the hatch. As you open and close the hatch, there is a wire bundle that flexes, and a flexed wire will eventually break.

Ah - so you CAN bottom post - well done old chap! Of course I can bottom post, but my news reader defaults to posting on top, and when one can read the entire original post and my reply all in one screen, I see no reason to even care about top posting. I am a rude son of a bitch though, and it bothers me not to suggest that you are far too anal. Try posting something that is relevant, and I might change my position -- but I doubt it.
