2001 Olds Silouhette - The blinker on the dash blinks quickly

If the dash signal is blinking fast and the back of car signal is NOT working, then the problem is the bulb in the back of the car. The one that is not blinking needs to be replaced. The bulb that's not blinking is burned out, and this changes the resistance of the blinker circuit causing the blinker to flash rapidly on the dash indicator. FIX: Replace the burned out bulb in the back of the vehicle.

Note - Sometimes this situation causes the blinker module on the fuse panel to permanently change to a rapid or even a non-blinking state. In this case you must also replace the blinker device itself, which is on the fuse panel and looks like a small cylinder (or cube) less than one inch in diameter.

Your problem is either a bad bulb in the tail light/brake lights or your turn signal switch is bad. I'm more inclined to say that the problem is the turn signal switch and you need to replace it.

Check the switch

1st off the right blinker,does it blink fast or not at all if it blinks fast, check the bulbs if it is not blinking and the dash light also don't work the multifunction switch could be bad(turnsignal,light switch) if your other break light is working start by checking the bulbs take the verified good one and try it in the other side if the bulbs are good check the fuses under dash and under hood carefully

the fuse is broke

ONE OF THE BLINKER DOES NOT HVE CONTACT WZ THE BULB.....USE A THIN AMUMINIUM FOIL N SCREW THE BULB OVER IT,,,SOMETIMES DUE TO RUST OR SEDIMENTS MUST HVE BEEN STUCK TOT HE CTC POINTS.

under the dash you should find a round metal container that either plugs in or has wires leading to it that is the indicator relay you should find that is the problem hope this helps regards Jim

The blinker usually blinks fast when a turn signal light is burnt or not contacting. Check the signal bulbs to see if they are contacting or in good condition. If that is not it. Try replacing the blinker under the dash.

the flasher likes to fail. Check that next.
