Dodge Mechanic: sprinkles08, Chrysler/Dodge/Jeep master tech replied 12 years ago The first thing you will need to do is remove the headlamps. There are 3 screws that hold the unit to the body. Remove the the lamps, remove the bulbs. Using a test light test for power and ground at the bulb connectors with the lamps on.
Why are my head lights not working in my minivan?
The problem lies in the FCM, BCM, or the multifunction switch. However, the FCM is the most likely culprit. If one of the lights does NOT work, then you have to check the green wiring connector located at the bottom of the IPM. You want to make sure you’re getting power through the IPM and into the wiring harness.
What to do if your headlight doesn’t work?
One headlight works on low beam and another on high beam. Or the lights work erratically. Start your diagnostics by removing the FCM located in the IPM. You’re going to bypass that module and try to “hotwire” the headlights yourself to eliminate the possibility of a bad FCM. After you pull the FCM, look at the connector on the front of the IPM.
How does a headlight switch work on a car?
The headlight switch doesn’t actually do any switching. It’s built with a series of resistors. The switch has 12volts coming into it. As you move the switch, the resistors reduce the voltage, depending on where you set the switch—high beams, low beams, parking lights, flashers, etc.
How can I tell if my Dodge Caravan headlight is working?
Using a test light test for power and ground at the bulb connectors with the lamps on. Check the black/light green wire on the left for ground, check the black/tan on the right. With the low beams on you should have power on white/dark blue left, white/tan on the right.
