Procedure notes
The video above shows how to check for blown fuses in the engine bay of your 2004 Pontiac Grand Prix and where the fuse box diagram is located. If your map light, stereo, turn signals, heated seats, headlights or other electronic components suddenly stop working, chances are you have a fuse that has blown out. Fuses should always be the first thing you check if your Grand Prix is experiencing electrical difficulties because they are relatively easy to check and inexpensive to change. The more electronics your Grand Prix has, the more fuses it has. Some Pontiacs have multiple fuse boxes in the engine bay, so be sure to find the fuse(s) in question. Some components may have multiple fuses, so make sure you check all of the fuses that are linked to the component in question.
If you need to replace a blown fuse in your Grand Prix, make sure you replace it with one that has the same amperage as the blown fuse. If checking and replacing the fuse for the component in question doesn't work, we recommend seeking assistance from a trusted professional mechanic. They should be able to figure out if the component needs to be replaced or if there is a short or some other problem with your Grand Prix.

上述视频展示了如何检查您的 2004 庞蒂亚克 Grand Prix 车辆发动机舱内的熔断保险丝，以及保险丝盒位置图的所在位置。 如果你的仪表灯、音响、转向灯、加热座椅、大灯或其他电子部件突然停止工作，很可能是保险丝熔断了。 如果您的Grand Prix出现电气问题，应首先检查保险丝，因为它们相对容易检查且更换成本较低。 Grand Prix 的电子设备越多，通常配备的保险丝也越多。 部分 庞蒂亚克 车型 在发动机舱内有多个保险丝盒，请确认找到的是相关保险丝。 某些部件可能由多个保险丝保护，因此请检查与该部件相关的全部保险丝。
如果需要更换 Grand Prix 上熔断的保险丝，务必使用额定电流与原保险丝相同的替换件。 如果检查并更换相关部件的保险丝仍未解决问题，建议向可信赖的专业维修人员求助。 专业维修人员应能判断部件是否需要更换，或 Grand Prix 是否存在短路等其他问题。
