Re: 2003 regal clusters flash on and off several times...
Might be the crank signal sensor, try turning your key to the on position and all the lights on the dash should flicker on and off leave the it in the on position and go to the passenger side fuse panel and take out fuse 4A, the fuse for the CRANK SIGNAL , BCM, CLUSTER. if your dash stops blinking then its probably your crank sensor.

seen this before you need to get the speedo out and tap it down. it will be stuck. that is if it stays there with no power or ignition on, if not then its a short in the speedo or its wiring. and feeding wrong volts.
yellow light (check engine) (fuel) (abs) (e brake) these are the most common. Check engine usually looks like a little engine, fuel light is usually beside your fuel gauge, abs light usual is a circle and the ebrake light could be just a light
This generation of Buick seems to have a faulty speedo cluster illumination circuit.
I have an '01 and an '02 and they both have the same problem with the dash illumination.
I use the 'FEEL' sollution ;
When you start the car you can assume it is in PARK.
the next spot down with the shifter is REVERSE.
Next is going to be NEUTRAL.
And then DRIVE.
So, from PARK , 3 possitions down on the shifter is going to give you DRIVE.
The alternative is to replace the instriment cluster on you car.
you may have a faulty vehicle speed sensor in the transmission. the ses light came on because the PCM also knows that the speedo is not working. you may have also noticed the transmission dosn't shift right.if you have accsess to a scan tool you can check vehicle speed on the data screen. if the scan tool reads corect vehicle speed than the problem may be in the instriment cluster.
Hi stan, 3 and 4 just sound like a bulb remove the instriment pack and try two new bulbs. 2 is the one to think abount i think this is only one led bulb if you move the lever does the light flash, there is a setting for this D
