Dash board instrument cluster flashing

One of the contacts for the turn signal bulbs inside the instrument clusters is loose and may need resoldering. You will need to open up the cluster and check for continuity from the turn signal LED bulbs to the electrical connector plug. In our case, we found an open circuit.
Follow this procedure to troubleshoot this problem.

1. Remove instrument cluster from the dashboard.
2. Open the instrument cluster. Remove the back cover from the instrument cluster.
3. Once the circuit board is exposed inspect the contact where the turn signal sockets are connected to the circuit board. In our case one of the turn signal socket pins was broken and not making contact with the circuit.

Piggybacked 99 XJ from 2014 DEC. ok. no biggie.
but what car, same? XJ up to 2001?
op my guess he blew fuse 9 or 16
i bet the self test failed with the OP's car.
but lets talk your car, is it a 99 XJ?
the FSM covers this.
here is the full answer here. see instrument pages, read.

the used head will not work it has the wrong VIN stored inside it


other tricks are here, including ASD stalls. and free books.

1999 XJ? facts on head,
pdc fuse 16 blown?
cab fuse 9 blown?
self test fails.?
now the hard wired warn LAMPS just this one year 99
seat belts
and low washer fluid
ABS fail.
brake warn. or hand brake engaged
chime inputs. hard wired.
tURNS (L/r) active and high beam.
illumination (back ground glows) works, hard wired TOO.
DEAD LIST.
all else will be dead if COMMs are lost or fuses out. depends on which fuse is dead, if both blown all warns dead and gauges.
meters all dead. with loss of comm and some warns below.
cel dead.
upshift dead
low fuel dead or stuck (stuck on or off is still dead)

the photo below shows why meters die
when comm LINK dies. or 12v power to head.

have the BCM checked for codes, this sounds like a communication problem between the BCM and other modules in the car.

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.

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.
or

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

I have a similar problem - every once in a while all of my dash lights flash on like the car is trying to conk out/stall (I have a 2006 Jeep Grand Cherokee) - the car has no loss of power and runs fine, just all of the dashboard lights and warnings come on like its going to stall. Happens on dry days, wet days, cold days, warm days - at least 3 times a month. trouble is, because its intermittent no one can find the problem.

This is commonly caused by a voltage problem from the battery when one or more cells is damaged or dead. You can take your car to most auto part shops or even WalMart to have them test the battery (should be no charge) and see if you need it replaced. Usuall, while driving you will lose all power in your instrument cluster and it may flash a couple of times then come back up. I had the same type of symptoms the first time I had a bad battery in my 06 Commander at about 60K miles and again at about 105K

The warning chime of 5x5 is a sign that the SRS ( airbag ) light is burnt out, and there is an error with the SRS system.

Verify SRS ( airbag ) lamp operation, turn the key from off to run ( do not start ) the airbag lamp should illuminate. If not, it is burnt out. Need to pull the cluster and replace.
( thread at F150online.com on cluster removal in the how to forum - titled about changing cluster illumination color or installing a cluster overlay ).

Once you replace the SRS bulb, you will get a LFC ( light Flash Code ) of a 2 digit number.
Example :
flash flash flash flash { short pause } flash flash { longer pause } flash repeats the same for 5 times, the solid on.
This is an example of a LFC 4-2. Once you have the LFC start a new problem with the LFC and we can get that fixed after you get the bulb replaced.

It sounds like a poor Ground connection, Start by checking the connector that connects to the Instrument Cluster then see if one wire is terminated to the Metal components of the Dash Board. This would be the Master Ground connection for ALL Instrument lights and typically would include any other Lights on the Same Circuit. You will most likely find a loose sheet metal screw making this Ground Connection. With a high resistance connection the lights would be somewhat dim. If they flash between Dim and Bright it is an intermittent connection causing it. Almost always this will be found to be a loose screw connecting the Ground to the Chassis.

check the positive ground wire to your fuse box if it is loose it can cause the lights to flash. thanks to ranye for the help

I have the same problem.
