1997 Jeep Grand Cherokee Laredo interior dome lights come on sporadically, usually when road is bumpy but not always. Then lights and door locks go on and off repeatedly.

Dealer changed door locks in front doors, did not solve problem.

So if the car worked perfect at the dealer
( i bet it did)
then he is a crook because, is not god like.?
how can you fix a car that tests ok.
you tell me... Ill bow in reverence.

find a shop that can drive it for a week and fix it.
it has to fail for them to find it.
diagnosis is that, using tools to find a live failure.
i could fix it but it might take me 1 to or more days work
driving and with my data logger attached, to find the culprit.

    I can also bypass 1 switch at a time
    and drive and find the bad switch.
    this cars wiring is complex. (and PCM/BCM logic)
    Intermittents are never easy to find.
    unless persistent, 1 fail per day, HARD>
    see? 1 per minute super easy.
    there are many ways, to find this.
    I have in my shop tools to allow me to the all. but guessing that be very hard.

    scan tools. to see them LIVE as they happen
    and my scan tool I can drive for hours.
    and log all live data...
    analog loggers, (its a custom box, that has multichannel, A/D inputs, that i designed.
    A kinda voltmeter with 10 channels , and computer logger to flash memory. (record and play back to hearts content)
    this I use on the most difficult cases.

    and jumper wires, that by pass switches.

    tools, win. and Skill's to use them and lots of time,
    in most shops the time factor is near zero.
    so they find nothing,. but not all.

    Agree with additional wires and manual switch, for temporary testing. It is probably humidity in light installation and it's not easy to prove that.

Dealer is a crook!

Everything points to something in the door being wrong, but not the lock. My guess is that a wire is cut or chaffed or touching another and is causing this.

The dome light is controlled by a pressure switch in the door or door frame. Some cars will turn the interior light on when you insert and turn the key. The inside of the driver or passenger door is the place to look.

Interior lights will not go off in my 1997 Jeep

name a lamp. there are many, why post with no lamp stated?
did you read the operators guide, on topic yet
open glove box see opr, guide, read interior lights page.
and read where each lamp switch is?
in all cars the door open switch turns them on
or the , dash command switch that does.
some have switches in the lamps domes.
if the manual switches area all off then it must be a door switch stuck
in that case, unplug them all one by one to find the curprit.

1996 jeep grand cherokee no automatic interior lights

1. If you have the light switch in the wrong mode the lights will not operate when you open the door.

2. If the interior lights do not operate at all (ie you cannot switch them on and off manually)then you need to check the fuse for the interior lights.

3. When set to the correct mode, the interior lights will operate from a door operated switch so if the switch has failed the lights will either stay on or not operate at all when you open and close the door. Eventually these door switches fail with repeated use and need to be replaced. (Consider how many times the small door switch has been operated since 1996).

How to turn off the dome light for 1994 jeep grand cherokee laredo

There should be a switch or rotary dial on the dash to shut off. If it continues to stay on its most likely a faulty door jamb switch. Inside each door there is a little plunger type switch which closes when the door is closed. However it closes a contact when the door opens completing a circuit to the interior lights. If one of the switches is corroded or shorted (meaning the wire is touching metal or internally shorted in the switch) the lights will stay on. You will need to remove each switch separately and disconnect, when the lights go off thats the bad switch.
