You could be hitting the flash feature on the turn signal arm when you use it.
because you turn them on and off, on and off...
a: you have a shorted filament in your turn signal light (arcing from turn filament to park light element, b: you have a bad ground at the headlight orturn signal associated with the issue c: you have the incorrect bulb installed in one of your turn signal lights d: most likely, you have a burned out bulb on one of the front side markers (these flash with the signals when headlights off using the ground plane of the parking light, as well they flash 180 degrees out of sync when parking/headlights on.
There are a couple of different times when you'd turn off your headlights. You'd turn off your headlights when the car is off for example.
a bulb is out
The headlights should turn on and off automatically depending on which setting you have your switch set at. The switch is located on the turn signal lever. I always leave mine on auto.
Check the contacts on the turn signal bulbs. Sounds like there may be a crack between the two contacts allowing the headlight/tailight voltage to cross over onto the turn signal contact. Hope this helps. josney613@hotmail.com
To replace a turn signal switch on a 2003 Pontiac Aztek, also known as a flash relay, the steering column must be removed. The flash relay is located under the turn signal. Remove the mounting hardware and the unit can be taken off.
do the headlights come on automatically or manually, if manually turn off
The multi-function switch inside the steering column has the turn signal lever and hazard lights button extending outside of the steering column it operates - turn signals - flash to pass - high beam headlights - windshield wipers ( on/off ) and intermittent speed settings for the wipers - windshield washer fluid squirter button
You have a dual-filament signal bulb somewhere with a bad ground. Turn the headlights and turn signal on. The bulb with the bad ground will go completely out at times, even though the headlights are on.
Yea, check the ground in the front turn signal socket. You'll probably find that the ground connection is corroded or completely disconnected.
