Dodge Caravan Headlamps: Their Common Problems and How to Diagnose Them
The headlamps of your Dodge Caravan were designed to illuminate the road when you drive at night and to reduce traffic-related accidents that happen mostly at nighttime. However, the sufficient lighting the headlamps provide is limited, and the headlamps will eventually show signs of wearing down. If you notice that the headlamps of your vehicle are acting unusual, then you should inspect it and do some troubleshooting before you drive out. Listed below are some of the common problems you might encounter:
Blinking headlamps
When the headlamps of your car flicker on and off, you should check the switch relay located near the vehicle's computer control box. A voltmeter is a tool you can use to the check if the relay has current or it already has a short circuit. Another part you need to check is the car's starter. If it has been replaced recently, then you should have disconnected the battery before installing the new one. This could have caused the headlamps to start blinking.
Faulty headlamp switch
Another problem that could cause your headlamps to malfunction is a faulty headlamp switch. Through constant use, the headlamp switch can fail to rotate back into its proper position. You may hear the switch click when you turn it, but the other parts inside the switch assembly are turning freely afterwards which cause the headlight to fail. The best thing to do is to get the switch repaired or replaced.
Only one headlamp works
If you have noticed that only one headlamp is working, then this problem may come from broken wires behind the malfunctioning headlight. The first thing you should do is to check the condition of the wires. If they're good, then the next thing you need to check is the car's front control module. A scan tool that can read the fault codes can help detect the problem faster.
No low-beam lights
When you experience this problem, what you need to do is to check the light bulbs first if they have power. The bulbs may be burned out and needs to be replaced. However, if you have just recently replaced the bulbs, then the problem could come from the relay. You can try and bridge the wires from the power distribution box to see if the relay is the source of the problem.
