the answer is one obvious fault; from one of two probable problems:
the buggered part is the DRL module [Daytime Running Light], but it may have just been the module's time to go, or it may be a manufactured defect in the cavalier's wiring loom, located just inder the battery tray at the left front corner, causing a short circut, thus cooking your DRL, killing your headlights, and causing the flashy 'we've got a problem' light to show on your dash
If you're talking about the green head light indicator to the upper left of your speedometer on your dash, that's the daytime running light indicator (DRL). The high beam indicator is a blue indicator and is inside the speedometer arc. A lot of people confuse these two indicators. The daytime running lights may be disabled by preferably removing the DRL fuse in the fuse box in the driver's door jamb or engaging the parking break.
you lost ground to one of the light sockets or hqve a bad socket in one of the lights
Generally, a blinking DRL indicator on the dash means that there is a headlight burned out. Replacing them is cheap and easy.
I have a 2003 sable, and had the same probelm. By looking at the owner's manual, I found at that it was and indicator that something is possible wrong with the transaxle and if it continues flashing, your car needs checked. Mine flashed for a couple of hours but as soon as I restarted the car, it hasn't been back on since.
I think these cars have lamp circuit sensing. It may be caused by a blown lamp or incorrect lamp (wattage). This is only a guess, but I have seen it in other makes/models. Good Luck The DRL relay inside the gauge cluster has been blown. The only way to fix it is to either replace the whole cluster (easiest) or dissemble and replace the DRL relay.
How do you use the "AV" indicator in the contact lens.
in the flashing area
Did you check if the bulb is ok? Normally if a bulb is burned out the speed of the indicator inside the car increases significantly.
the metal lip on the inside of the gutter intended to act as an edge flashing
Often a fast-flashing turn indicator (inside the car) means either the front or rear turn signal bulb is burned out. Check the actual turn signals and see if they are working. If not, just replace the bulb.
no you need a dial indicator
