I have a 2002 cavalier if my headlights are off when i put my car in reverse my right headlight flashes will fast for a couple seconds then stops & then i get a wrench service light & i notic

What does the rear turn signal do? If one of the signal lights are not working, the other will blink faster. With the headlights off the turn signal bulbs ground through the light holder. With the headlights on the running lights are using the same ground circuit. Make sure all bulbs are good with a good ground.

the flasher module is under dash near the steering column. could be bright green if OEM. if the low beam light is out, try replacing the bad bulb. that should correct the issue with the headlights.

Your right rear turn signal bulb is blown.Replace the bulb and the fast blinking will stop.

disconnect battery for about 10 minutes. then reconnect. gives alarm time to reset and everything should be working fine.
when headlight went out it broke the circuit to alarm . now all you have to do is reset. ez

means your daytime running lights are on,when you turn on your headlights it will go off,it reminds you to turn on your headlights at night

turn on your 4 way flashers go in front and back of car see witch light is not flashing its blown must replace easy fix good luck CJ

sounds like there is a problem with the day time running lights my does the same thing but because i installed HID light so i no long have day time lights try changing headlight bulbs if not then its a short

check the relay and blown out bulbs will cause the lights to blink fast or some to stay on. one bad bulb will cause the problems.

There is a circuit breaker inside the headlight switch body. It gets weak over time and use. The breaker is actually mentioned in the owners manual. A new switch is about $75.00 at the local parts store. You must remove the front of the dash to change the switch. Mine would go off and then in about 30 seconds reset and the lights would come back on. I would be driving down the road with my headlights flashing as the circuit breaker opened and closed. New switch = problem fixed.

i actually just did this a couple days ago, this takes about 20 minutes and a little bit of patience. When you pop your hood you will see a protective piece of plastic over the headlights/radiator, you firstly have to remove the plastic clips holding that piece then pull that piece of plastic off, once done u will see 2 bolts holding each headlight in place, i believe it is a 9/16 socket but if not just find the one that fits, remove the 4 bolts (2 for each headlight) and pull the headlight in an up and outwards manor. if you feel any resistance do not yank look at why it is catching and clear it, then it should just pop out (the headlight and the corner piece and clipped together so dont pull it too far out) then when the bulb is accessible pull the old bulb, put the new bulb in and voila place the headlight back into position, redo the 4 bolts holding the headlights and re-attach the plastic headlight/radiator cover. Enjoy the new lights
