So despite the ever growing Honey-Do list, I scooted off to the garage yesterday and swapped out the gizmo that locks/unlocks the trunk. The plastic connector that grabs the arm leading to the lock had broken and the trunk would not lock/unlock with the rest of the locks.
After an hour of cussing, fighting, wriggling, etc, I got the replacement part installed and hooked up. What a PITA. I think they built the car around that part...it was a bitch to R&R. I'm still not sure I got it right as the car will not unlock from the trunk, but that's not a big deal. The trunk locks/unlocks with the other buttons... Not bad for a $20 investment (used part) and an hour of time. Now to get back to the Honey-Do list before she notices... Lee '93 300D 2.5 181K
