The video above shows how to check for blown fuses in the engine bay of your 1999 Mercury Grand Marquis 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 Marquis is experiencing electrical difficulties because they are relatively easy to check and inexpensive to change. The more electronics your Grand Marquis has, the more fuses it has. Some Mercurys 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 Marquis, 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 Marquis.
