Turn signal shorting out

There could be several reasons why the driver side headlight on your 2007 Pontiac G6 is not working. Some possible causes include a blown headlight bulb, a faulty headlight relay, or a problem with the headlight wiring. It's also possible that the issue is related to the turn signal, as you mentioned that it was staying on. I would recommend checking the headlight bulb first. If it is blown, replace it with a new one. If the bulb is fine, the issue may be with the headlight relay or wiring. You can also check the turn signal switch or the multifunction switch, which controls the turn signals and headlight. It may be possible that the switch is defective or malfunctioning. It would be best to get the vehicle inspected by a professional mechanic to determine the cause of the problem and make the necessary repairs.

was the correct bulb used? this sounds like a single function bulb was used NOT the bulb that will light with the headlights and ALso produce turn singles

on 1998 and earlier models, the side marker light housing is located next to the headlight housing. Remove the screws and pull out the housing to access the bulbholder on the back of the housing. On 1999 and later models, the park and turn signal bulbs are located in the bottom of headlight housing. Twist the bulbholders out to replace the park or turn signal bulbs. Installation is the reverse of the removal directions.

Chances are you have a short or a bad ground in the circuit.
I would check for voltage and ground at the sockets for that side.
The parking light voltage is grounding thru the turn signal side thru the indicator lamp on the dash.

The circuit board needs to be replaced. Which is the board that the bulbs sit in. If you remove the turn signal bulb. You will notice the bulb socket will be slightly burnt inside. I had the same problem with my 99 Denali and replaced the circuit board for $35.00. Now everything is fine.

could be a short,but more than likely the bulb receptical has a worn contact so the receptical needs replaced.

This simply means that the front driver side turn signal bulb has failed. Replace it.

YOU HAVE TO THE FRONT HEADLIGHT HOUSING TO REPLACE THE TURN SIGNAL BULB.

I have taken my car to many shops to solve this problem. Long story short your tail light has a bad circut and entire lamp must be replaced. (Lamp cost approximate $130.00)

That is probably the relay, start replacing the turn indicators relay.

If thet does not work , then it is probably a short on the instrument panel stick.

Check also the indicator fuse.
