Dodge Ram 1500 Headlights
Detecting Causes of Bad Dodge Ram 1500 Headlights
It's not a good sign when the headlights of your Dodge Ram 1500 begin to act funny. These are parts that you would want to be steady and reliable especially during nighttime drives. Unfortunately, the Ram is plagued with various lighting issues that have hard-to-identify causes. The obvious solution to headlights that won't turn on is by replacing old bulbs with new ones. However, it's possible that doing this is too easy to be true. Read this guide to help identify the signs and know the symptoms of bad Ram headlights. To give you a lead on how to tackle the issue, we've included probable causes to help you diagnose and solve the problem.
Headlights don't turn on.
Test the stock bulbs first on another vehicle or on a tester to see if the problem is with the lights or with the truck's electrical system. If it's in the system, a common culprit is a faulty headlight switch. No amount of turning a bad switch will result to lights that will turn on. Other than this, moisture on the fuse and other parts when the car is subjected to cold weather can also affect electrical flow.
Lights are limited only to high beam or low beam.
Functional headlights should be able to change between low and high beams with a simple turn of the switch. If what you have on your truck are headlights that only ignite on one setting and die on the other, check the wiring going to and from the assembly. There might be a short somewhere in the circuitry that disrupts the current to the headlights. Other than this, it's possible that the ground wires for proper management of high-voltage leaks aren't connected properly.
Bulbs flicker or only one side works.
This is one of the most complicated issues associated with the Ram's headlights. There are two main routes you can take to diagnose this kind of problem. First, check for any loose or damaged wires and connections. Second is to check the truck's Front Control Module which acts like an electrical relay. The latter route is more expensive and time consuming to do. But if the problem lies in this part, replacing this ensures you of reliable lights in the future.
