Driver's side electric door lock doesn't unlock..

[96tsport]

..with the drivers side master button set. All other locks work normal though the one in the sliding side door seems a bit lazy & doesn't fully work.

Not sure if the driver's power door lock should unlock using the driver's side door lock switch, or what the problem might be? ..cos works normal with the remote (lock & unlock).

All of a sudden works normal. Wasn't sure if with the engine running ..or something..drivers side door doesn't unlock.

Have the panel off for other repairs & 'd like to sort this out before buttoning up.
