How do you fix drl on Dodge Caravan 2002?

Answer 1

Assuming this stands for daytime running lights, the first place I would check is the fuse. If this is good, check the high beams and light bulbs. If this stuff checks out, the next place is the relay, which should be under the hood. A relay is just a switch that uses electricity to operate it, rather than your fingers. Find the relay and remove it. (I would recommend a service manual) there are four or five leads. There are two control leads; one from the ignition switch (or body control module) and the other to ground (or the BCM). One of the control leads needs to have 12 volts when the ignition is on, while the other will go through the BCM to ground. The load leads (the ones controlling the lights) will have one lead ALWAYS ON and another to the lights. Test these with a good test light. If this checks out, replace the relay. This is most likely the culprit. If the control and load voltage checks out, but the lights don't light (and the bulbs are ok) you may have a bad ground (rust) or if the control part doesn't work, you may need to take this in to have the BCM checked out. I would be careful messing with wiring as you can really tear things up if you aren't.
