Your Pontiac Grand Prix tail light assemblies are built to endure the toughest driving conditions. But like all things, these components still succumb to the everyday wear and tear and cause different problems like malfunctioning tail lights or water-filled assemblies. If you see that your tail lights aren't functioning well and aren't in top condition anymore, give them a quick check-up and see whether they need to undergo some troubleshooting. Here are some common tail light assembly problems you will encounter as your Grand Prix continues to drive thousands of miles.
If you're experiencing malfunctioning tail lights, don't worry. This is perhaps the most usual problem any tail light assembly has. A burned-out bulb is usually the culprit for an unlit tail light, but this is the case if only a single assembly stops beaming bright red. Should this be the scenario, removal of the bulb is needed to have one of its filaments checked for any signs of breakage, which calls for a replacement. However, if multiple tail lights stop working, the fuse should be inspected. And if for some unfortunate reason that the fuse isn't causing the light malfunction, pass the blame to the damaged or loose wiring near the tail light assemblies and under the car.
Rain water inside tail light assemblies is normal especially if you live in a humid area that experiences frequent heavy rains. Condensation, however, shouldn't be left unfixed as trapped water can cause the sockets and wires to get faulty. Should you experience this on your Pontiac Grand Prix, remove and dry the assemblies, and then use a silicon sealant or glue to cover up any open areas where water can enter. Make sure to completely reseal the lens to the tail light assembly and secure the sockets from any possible moisture. This troubleshooting should keep your tail light assembly dry inside.
A slight mistake in maneuvering while parking can cost you a cracked tail light assembly. Huge cracks normally require replacement, but small-sized chips can still be salvaged using a tail light repair kit that can be purchased from any car store. With this kit, you can create a mixture that needs to be applied on the damaged area and make your assembly look just fine.
