Common Causes of Dodge Ram 2500 Fog Light Kit Problems
Fog lights are pretty darn useful. They allow you to traverse the highways even through the thickest fog, making your journey much more manageable. Unfortunately, they are vulnerable to some road elements that will leave them barely functioning. If you can diagnose them correctly, fixing the problem could be much easier. Here are some of the usual Dodge Ram 2500 fog light kit problems and the culprits behind them:
No power to the fog lights
If no power is going to all of the fog lights, the fuse must have burned out or the relay could be malfunctioning. Open up the fuse box of the Dodge Ram and look for the appropriate fuse. If there is no more connection between the wires within or if they look blackened, replace it to solve your problem. If that doesn't work, try replacing the relay.
Dim and unclear lights
Check out the lens of your fog light. It could be dirty, or there could be some moisture inside. To clean out the dirt, you may need to disassemble the fog light to be able to clean all of the components thoroughly. If there's internal moisture, the seal of the housing may have been broken. The fog light needs to be taken apart and allowed to dry. After putting things back together, apply the sealant on the right areas. For an older fog light lens, you could try polishing it with some chemicals or sandpaper. White toothpaste is also a good alternative for polishing the lenses.
One of the lights have gone out
Faulty electrical wirings or burned-out bulbs could cause fog light problems. Check the wires and the electrical connections going to that particular fog light. If they are loose, just tighten them as necessary; damaged wires should be replaced. Take a look at the bulb; if it looks burned out, then you have to replace it.
Dim fog lights grow brighter when the engine is revved
You might have a problem with the alternator and the charging system. Use a voltmeter to check the charging voltage of the Dodge Ram, which should be about 13.5 to 14.5. Lower readings mean that your alternator is going bad or that there is a problem with the alternator drive belt.
