Hi,

On my '90 Loyale, the switch that operates the courtesy light also
operates the "door ajar" light. You might try shooting some contact
cleaner, or even WD-40, into the switch and operating it a few time.
They sometimes get junk in there, or corrode. There may be a rubber
cover over the switch you'll need to pull off to get to where you can
shoot some "stuff" in there.

That's all I've got right this minute...

If it helps any, these circuits typically run a hot lead to the dome
light and indicator and opening the door activates a switch that
grounds that circuit. I'm not sure if your 91 legacy is set up that
way or not. If it is, however, you may have a short in that wiring
somewhere that is grounding that wire somewhere other than the switch
associated with the door. You'll have to find that wire.

It can be a pain in the ass to track these down. A wiring diagram
will be something you'll need to get started in where you can cut to
float that problem door.
