Door open warning light

no year, now that makes this very hard,...????????????
I roll my dice and land on 2007+ GC
must be the non EVIC display option car, as the fancy display tells you.
but like mine, it only shows DOOR.
so which door.
well that is easy, or hard.
1: easy, connect scan tool bingo, you get scan DTC codes for door.
2: hard, use a voltmeter at every door switch , bingo, bad switch or wire or corroded connector

2005 jeep wrangler when i turn lights on beeping starts

did you RTM read the operators guide yet,
it tells you why all beeps beep and what lamps flash, (warning) and why. did you?
you turn on, the head lights, (what about 1st click , parking lights"?)
and does the dash cluster, show warnings of any kind?

if a door is ajar the system will think, you are exiting veh. with lights on and tell you, buy beeping ,etc.
but on my jeep it says on the dash DOOR, or on EVICs, (not yours)
the newer car even tells what door IS AJAR.
mine on shows , "DOOR"
the operator guide will say, check all doors for ajar, and get warning clear before driving....etc.

if you lost the guide here it is for free

click the 05 link
ignore beeps, there are just too many .. i look at the cluster and learn to read it..
my newer jeep 08 can produce 1000s of errors,,,,, possible.
in fact the intent it to beep to tell the driver to look at the cluster
for in depth, causes.
see chapter starting on page 136'

once sound it makes is Check gauges chime. so check them.
and headlamps left on
and door ajar.

page 63
NOTE: If the driver's door is left open, and the headlights
or parking lights are left on, the "High Beam
Indicator Light" will flash and a chime will sound.
Lights-On Reminder
If the headlights or parking lights are on after the ignition
is turned off, a chime will sound when the driver's door

its a crude system, and evolved to complex in 2007.
"DOOR" or RF-door , on mine.

NOTE: A tone will chime if the turn signals are left on
for more than 1 mile (2 km).

When I open the driver's door and take out the key from ignition, there is a constant beep different from the one I know and the dash board always flashing. What could be the solution.

The beeping sound is a warning sound that lets the driver know that a door is open and he shouldn't drive off. It is normal and nothing to worry about. Good Luck. george

Door buttons not working since boost.

Can't be boosting today's car or bad things happen

Dead batteries have to be disconnected & charged

Now you will pay several hundred to diagnose those issues

The door open bell rings all the time even though all doors are closed it is a 1996 plymouth breeze

you have a sticking door ajar switch in one of the doors, the only way to isolate it to the problem door is to disconnect them one at a time, start with the drivers door.

My car keeps beeping like the doors are open....but their not. The light keeps flashing too. I dont know how to fix it.

if it is cold were you are at .sometimes the sensor in the door latches gets sticky .the most likely fix would be to replace the drivers side door latch.because this is the most used door.a good shop can tell you for sure which latch it is for sure.thanks for your question i hope this helps.if the beeping goes on after the car is shut off and door is closed get latch fixed soon because this will draw down your battery!

the door ajar switch in the drivers door latch is is either shot or drivers door spray some WD40 in the latch,open and close door several times and if the switch is only sticking this will free it up.

2001 Boxster Alarm Beeps Twice when locking it and sometimes during driving as well. . . .

If the car beeps twice when you unlock the doors, it means there is a fault in the car alarm system. Usually when this happens the red LED lights on the "door lock" button on the top r h side of the dash. Also on mine, when you try to open the passenger door the window does not drop the small amount as usual, but that may be part of my alarm problem.
