To the right of your headlight switch is a dimmer switch for your gauge cluster lighting - I'm not sure if it's the same on your F150 as my Explorer but when my dimmer switch is rotated all the way up it turns on my interior lights . Also if you have a door ajar light lit up in your gauge cluster , you probably have a sticking door ajar switch
In a 1997 Lincoln Continental : To the right of your headlight switch in the dash is a ( panel dim ) switch I believe if that is turned all the way up then the interior lights will come on
Used for Interior Lights and Instrument Panel Lights.
If only the interior lights won't work, check the fuses.
are brake lights staying on or is brake in the dash on ?
Closing the door turns off interior lights on a 1997 Chevy S10 because there is a switch in the door jamb that closes when the door shuts. When the door opens, the switch opens.
Did you check the bulbs?
I have the same problem with my 1999. The tail lights as well as the interior instrument panel and the license plate lights are all not working.
If the interior lights come on and go of and chimes sound off f on a 1997 Dodge Caravan there could be a loose connection somewhere. This is a common condition with the Dodge Caravan series.
Probably a loose connection in the wiring or the bulb socket.
How's your battery, is the car starting properly. Maybe the battery or alternator.
