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.
Replace the door latch.
The dimmer switch when turned just past high, turns on the interior lights. There are switches in the door opening that turns the lights off when the door is closed. Either one of these can cause the lights to stay on if they fail.
On the interior lights for the back seats, there is a switch. When you turn the switch to "Door" mode it will make the lights turn on when the door is opened.
I would say 1 of your door switches are bad or your door doesn close all the way.
Could be the interior light switch on the dash is turned on or the door light switch is broken.
how do you install spring on interior door handle of a 98 chevy pickup
I'm not a mechanic / technician but on a 1997 Ford Explorer I believe that if the gauge panel dimmer switch ( to the right of your headlight switch ) is rotated all the way up it will turn on all the interior courtesy lights when the doors are closed Also , is the " DOOR AJAR " warning light on in your dash to the left of the fuel gauge , if so either a door or the liftgate is slightly ajar or a door ajar switch is sticking , I believe that will also keep the interior lights on
make sure ALL the doors are closed
Just to the right of your headlight switch is a dimmer wheel for your gauge lighting If the dimmer wheel has been rotated all the way up , your interior courtesy lights will stay on ( even with your doors closed ) If your interior lights are on with a door ajar indicator light on in your gauge cluster , either a door ,your liftgate , or your liftgate glass is not closed or you have a sticking door ajar switch (Helpfull)
spray WD40 in the door latch mechanism, it will sometimes get stuck and the lubricant will free it up to engage when the door is closed.
There is a broken or frayed wire in the door harness.
The interior lights fuse on the astra 57 reg is located on the door hatch.
