Every manufacturer configures their electronics differently in their cars. The Dodge Caravan uses a body control module to handle the turning on and off the turn signals. Many wires feed the control module information, so that the module knows how to control various devices on the vehicle. The combination turn signal and hazard flasher relay feeds part of the information that the control unit requires.

Replacement parts

Step 1

Locate the fuse box under the dash on the driver's side of the Caravan. Look near the emergency brake. The fuse box cover has two finger screws that you should loosen to remove the cover. Inside you will see a collection of fuses and in the upper right corner a few relays.
Step 2

Find the turn signal hazard flasher relay in the upper right corner of the fuse box. It should be easy to spot as it is the biggest of the relays in the box. Remove the relay and replace it into the socket from which you just pulled the bad relay. The placement into the socket is tight and can be difficult, but be patient and take your time.
Step 3

Look to make sure it ended up in the correct position. Close the fuse cover and tighten the finger screws. Start the Caravan and test all the light functions. Make sure that the turn lights blink and that the hazard lights work properly.
