Is there a way to set the dome light to turn on when the doors open? I have a 1993 S

Also what is the size of the dome bulb? I got a blue led in there right now but wanted a different color

 

The dome light switch has 3 positions. Off, door and on. I believe in the middle position the dome light should come on with the door. If I remember right the bulb is a3022

 

If it’s not coming on when the door is open, check your door ground, the little switch with black rubber cover next to the striker. This completes the circut when the door is open. And the middle location is correct for door ajar.

 

Thanks for the info guys. I still couldn't get it to work and am thinking it's a wiring issue or something. The light just stays on in the middle and last position.

 

you either have a ground short or the LED you have in there was wired weirdly. I would look at the dome light first before the door switch. Or maybe the switch is stuck low and connecting to the chassis all the time. If you unscrew it and the light goes out then you'll know it's the switch.
