Procedure notes
The video above shows you how to change a burnt out front turn signal bulb on your 2003 Pontiac Grand Prix. If the turn signal (also known as a blinker or flasher) blinks rapidly or doesn't blink at all / stays stuck when engaged, this is your Grand Prix's way of telling you that a turn signal bulb is burnt out. Troubleshooting for burnt out turn signal bulbs in your Grand Prix is relatively easy - turn your hazard lights on and check the front of your Grand Prix and then the back, whichever side is not illuminating is the side with the burnt out bulb. We recommend that you change both the driver and passenger side bulbs at the same time as they get dimmer over time and if one is out, then the other one is likely to burn out soon.
When changing the turn signal bulb in your Grand Prix, be careful not to touch the glass portion of the bulb with your fingers as this will cause the bulb to burn out prematurely.

上述视频展示了如何更换您 2003 庞蒂亚克 Grand Prix 车辆前转向灯烧坏的灯泡。 如果转向灯（也称为闪烁灯或闪光灯）快速闪烁或完全不闪烁、在开启时一直保持亮着，这是Grand Prix在告诉你转向灯灯泡已烧坏。 排查 Grand Prix 上烧坏的转向灯灯泡较为简单：打开危险报警闪光灯，先检查 Grand Prix 车头，再检查车尾；哪一侧不亮，哪一侧的灯泡就可能已烧坏。 我们建议您同时更换驾驶员侧和乘客侧的灯泡，因为随着时间推移，灯泡会变暗，如果其中一个灯泡损坏，另一个灯泡也可能会很快烧坏。
更换 Grand Prix 的转向灯灯泡时，请勿用手指触碰灯泡的玻璃部分，否则可能使灯泡提前损坏。
