The headlight assembly of your Dodge Caravan is there not just for looks. It allows you to have clear vision of what's in store on the road ahead. And to make sure that you are able to keep it working properly, regular troubleshooting is needed. Here are some tips to get you started:
When you either hear people complain about your lights hitting them, or when you are having blind spots in your car's vision area, then it is time to check the aim of your headlights. The usual suspects for this type of problem are the lenses and the contacts. It is either the lenses being nudged the wrong way or the contacts having a dent. To confirm this, first get your car into a dark space with walls, preferably your garage. Then, turn on the headlight assembly. Consult the manual if the height and angle of the light are within manufacturer standards. If not, then a simple adjustment should be able to get the aim back to normal.
If you are having trouble getting the lights to turn on, it is usually the fault of either the wirings or the bulbs. The first thing to check is the condition of the bulbs, since that part gets faulty easily. See if the filament has burnt out or if the whole bulb is broken. Do not worry; it is normal for bulbs to die out eventually, so a simple part replacement should do the trick. If it does not, however, then you should check the electrical connections of your headlight assembly. Fuses, switches, and wires should all be checked whether they are worn or broken. If any of them are, then use your electrical know-how to fix them, or replace the parts if they can't be saved.
Flickering or dimming lights from your headlight assembly could be attributed to either the alternator or the battery malfunctioning. Check if one or both of these parts are broken. A defective alternator or battery has a great effect in the lighting power of your vehicle. Without enough charge, the brightness weakens, resulting in dimming or flickering headlights. Replacing them with brand-new parts should be able to get the lights back to its normal brightness.
