I had the same issue with my dodge caravan and after several attempts by the dealer to fix it, it turned out to be a broken wire. They replaced the relay and it would work for a while and then go blank again. Have the wires checked thoroughly.

SOURCE: 1996 Dodge Caravan electrical problem, really weird.

The BCM provides the following features:
• Automatic door locks
• Battery protection
• Chimes
• Compass/mini-trip support
• Courtesy lamps
• BCM diagnostic support
• Door lock inhibit
• Headlamp time delay
• Ignition key lamp
• Illuminated entry
• Instrument panel dimming
• Mechanical instrument cluster support
• Power door locks (with/without remote keyless entry)
• Sliding door memory lock
• Vehicle Theft Security system (VTSS)
• Windshield wipers / washers (front and rear)

When mine went it caused odometer, fuel guage, power door locks and windshield wipers (except they worked when wash was pushed) to all stop working. I replaced it with and everything was good again. You need to replace with one from a van that has similar options from what I understand if you do not get a new part - they are expensive new i.e. $1000.00.

I did find these instructions on how to replace. I got mine from salvage making sure it was the same part number. Changing the BCM will cause your odometer to change to whatever reading the BCM came from.

It's not too difficult to replace the Body Control Module. If you know what you are doing you can do it in about 2 hours or less on a 1996 Caravan. The BCM is mounted on the back of the fuse box under the dash on the driver's side.
1. Disconnect the battery.
2. Remove the under-dash panel (plastic cover panel, metal panel, and metal brace.) You will also need to disconnect the handle for the emergency brake.
3. Remove three large screws holding fuse box in place (two on right and one on left.)
4. Remove the electrical connections at the bottom of the BCM. Avoid breaking the plastic retaining clips if possible. To release the clips push in at the tip.
5. You should now be able to pull the fuse box down a few inches, which is all you need.
6. Remove the screws holding the BCM to the fuse box, two screws on the right and one on the left.
7. Slide the BCM down and out to remove it from the back of the fuse box.
Reverse the procedure to put the new BCM in place. If you broke the retaining clips on the connectors you will need to use duct tape to hold them in place.

You can get free owners manuals online at:

or just type "owners manuals" in your search.

Here is a post I found that worked for my 2005 caravan.

For a 2001 Dodge Caravan: The owner's manual is vague, only stating that all fuses are under the hood in the fuse box, no diagrams. Once you have removed the fusebox cover, the diagrams for what each fuse does is provided under the lid. UNCLEARLY marked is the radio fuse, a 20amp fuse located 2nd row from top to the right of the accessory relay. It is marked: RDO/IP IGN.
