94 TS Executive wagon 3ltr V6 5 speed manual.
Using the key, the RHF door will lock and unlock all 5 doors.
The LHF will unlock all, but lock only the LHF door.
Is this normal?

wait till all 5 start unlocking and locking themselves a few times

while you are outside the car

spooky

What a ray of sunshine you are! Am looking forward to that .... not.

As a result of side swiping a concrete pillar I decided to change the driver door so I swapped the doorhandle into the replacement door. No probs except when unlocking it the other doors went nuts and opened and closed rapidly. I disconnected the driver door and that wasn't a problem so no problem really> If I want to reconnect, why does it do this and how is it fixed?

some one here knows

cant find that fix in this forum using search as yet

it was years ago .

It does that when a switch in the driver's door isn't making contact properly. Pull it apart and fix the switch, or swap in the bits from your original door if that was working correctly.
