Where do i find the switch for my read door light

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.

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.

I would assume the head light switch is the problem,and ,or the wires to it.

This is a do-it-yourself thing ...FREE! .. or maybe 30 cents...

The "push button" switch has te be adjusted.
The tailgate, just like each of your doors, has a push button switch that controls the light on/off.
It needs to be adjusted "higher" (needs to stick-out more....
If it is not loose, you might add a rubber pad to the tailgate where it comes in contact with the button.

Hope this helps!

chwck your door jam switches one of them is probably not switching off the power when you close the door.
make sure the dimmer switch is not stuck on for the interior lights

Hello Jtarchala,

Interesting (and doubtless very vexing) trouble...

I always recommend that an OWNER beg, borrow or BUY
the FACTORY+WORKSHOP+REPAIR manual..
but as that is not always an option...

I like to point out where FREE wiring diagrams and
TECHNICAL SERVICE BULLETINS (TSBs) can
be accessed (on BBB Industries website (registration
is required... as these are real documents))... for popular
USA Market vehicles.

I noticed the Manual switch (dash) was assumed to be the trouble... out of curiosity I tried looking up your switch...

Please note: while totally UN-SCIENTIFIC.. when I find
multiple BRANDS of a particular switch STILL (plentifully) available ...

I CONSIDER I have FOUND A PROBLEMATIC area ...

GUESS WHAT... Your switch is WIDELY AVAILABLE in large numbers (quite popular (a huge clue)..

Check them out: ROCKAUTO (examples)

Notwithstanding that screaming clue...
Each door and the TAIL-GATE also have contacts
which can jointly or singularly contribute to the problem.

Putting some body sealant (or play-dough) on the tip of each plunger... ( I would simply remove THEM and TAPE OFF the
connectors to TROUBLE-SHOOT)...

Again: hugely popular parts

Actually... including the courtesy timer module... this is a fairly complex circuit to trouble-shoot...

I hope I am helping.

I like electronics, circuitry (etc.)... Please feel free to comment
me or EVERY "FIXER" for more depth... & HAPPY HUNTING.

actually the problem is the switches for the doors and hatch get worn. the switch inside that sets the chime and dome lights. Open the door and look for the switch where the door meets the fender by the hinges. push each one in with your thumb. They should offer some resistance. and when you let go the button should come out back to original position. Check them all. even the hatch. look for any water or corrosion (green wires/ oxidized copper). Do one door at a time. I am thinking that seeing that it just started it is not a feature. But it may be a loose spring inside and eventually makes contact and shuts off.

the problem is the turn signal flasher module.

Does the door ajar light usually come on when the lift gate is open? The switch might be bad on it?

OK I had the same problem.  What is happening is, the door, while closed, is a bit loose.  When you turn left the force of the turn causes the weight of the door to close tighter, which in turn pushes on the light switch turning off the light. The solution - well you will need to look at the latch on the door, there are 3 bolts that hold the latch inside the door frame.  What happened to mine was that the sheet metal that the bolts go thru was cracking, causing the latch  to become slightly loose.  This may be what happened to yours.  but you will need to inspect the latch first, if there is no cracking, then the latch may just need to be adjusted and tightened.  If there is sheet metal cracking, then you will need to fabricate a solution, either by making a plate to reinforce the latch bolts, or (what I did, and it still works 6 month later) use thin washers under the bolt head to help stabilize the latch.  They must be thin as the bolts may not pass the striker plate clearly if they are too thick and the bolts are very shallow anyways.  If you choose to try yourself, remember that removing all 3 bolts will cause the latch to fall inside the door, so you'll have to mess with them one at a time. unless you are extemely handy, and mechanically inclined I recommend getting with a mechanic or body shop.
