98 Silverado Tail Light Circuit Board

The 1998 Silverado has a tail light circuit board that is prone to failure. The circuit board controls the brake lights, turn signals, and hazard lights. When the circuit board fails, the tail lights will not work.

This can be a major safety issue because other drivers will not be able to see the Silverado’s taillights. There are a few ways to troubleshoot the problem before replacing the entire tail light assembly.

If you have a 98 Silverado, chances are your tail light circuit board is starting to go bad. The most common symptom of this problem is that the tail lights will start to flicker or dim when the brakes are applied. This can be a very dangerous situation as it can make it difficult for other drivers to see your brake lights.

There are a few things that you can do to try and fix this problem yourself, but it is always best to consult with a professional if you are unsure about anything. First, check all of the bulbs in your tail light assembly to make sure they are tight and not loose. Next, check the ground wire for any corrosion or damage.

If everything looks good there, then the next step is to replace the circuit board itself. This is not a difficult repair, but it is one that should be done by someone who knows what they are doing. If you attempt to do it yourself and something goes wrong, you could end up causing more damage than before.

So please, if you are unsure about anything, consult with a professional!
