The trunk (boot) lid just stopped opening on my 1993 190E 2.6.  I can
hear the lock mechanism moving at the latch, but the trunk won't open.
All the other power locks work fine.  Does anyone have any clues on what
might be wrong and/or how to get it open?

Thanks,

Carroll

Make sure the lock is in vertical position... relock and unlock to see if
pressing the button will open up... if still not, then you need to check if
the mechanism is still attached to the lock... between the lock and vacuum
actuator.

If you can open the trunk with the key, you can check the linkage and
the vacuum actuator.  Otherwise, how do you check the vacuum actuator if
you cannot even open the trunk? X-rays?

Lock is vertical.

It's difficult to check the rest, since I can't get the trunk open.

Does anyone know how to get it open, short of drilling out the lock?

Stick the key in, do NOT push anything yet, turn key to the left, now push the button in with the
key turned to the left. Trunk should open.

When you push 1st and then turn the key to the left, you shear off the plastic linkage. It is
available at the dealer and is replaceable. You have to remove the trunk lock to replace it.

Thanks, Karl--that did it--the trunk is open.  As far as I can tell, the
  plastic linkage is just fine.  After getting it open, I first cleaned
and then lightly lubed the mechanism and the push button with silicone
spray and the system works perfectly, every time.

Not sure what the problem was--other than age and dirt.

You might have to readjust the rod so it stick out longer to actually unlock
your lock...

Thanks, Tiger.  It's working now--apparently just needed cleaning and
lubrication.
