When I turn on the blinker the headlights flash

CHECK THE BLINKER RELAY. OR ADD A BLINKER RELAY IN THE GROUND WIRE.

The problem was a bad left front blinker socket that was grounding out

check the ground wires to the rear lights sometimes the head lights will provide backfeed ground when off but cannot when on this would explain the rapid flash

Flickering headlights can get you a ticket to the policeman's ball, but more importantly, they may indicate trouble inside your car. This problem can result from many potential causes, but whatever the reason, you must identify and address it before your lights go out altogether.

Plain and simple...Your turn signal circuit is shorted to your headlamp circuit. What USUALLY causes this is an incorrect light bulb has been installed in the vehicle or the light bulb was installed incorrectly. There are other possible causes of these circuits being shorted together, but 99 out of 100 of the times that I have seen this it is either because somebody just replaced a bulb or a bulb socket melted somwhere on the car. Be sure to check both the front AND rear bulbs.

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

Generally, when you have a signal light that blinks fast it is an indication that one of the other signal lights are out. Check all of your bulbs and make sure they are the correct ones.

you have a left side turn signal out in the front or back replace bulb the reason why your bilnkers wont blink is because your flasher relay is bad the relay will be located n the fuse panel under the drivers dash any auto parts store should have the light and the relay in stock replace both of those and youll be in buisness

You need to check your left side turn/park lamp bulbs for correct part # & installation.If that checks out you deffinetely have a ground problem.When you have other lights blinking with you turn signals you have either a bulb incorrect or a bad/poor ground.If bulbs check out check your forward lamp harness ground.Hope this helps
