Having problems with your 1997 Dodge Caravan ?
The guages don't work, then, at any given time, they will just begin working. Nothing on the dash will work...no tach., speedo, temp, gas guage and automatic door locks...nothing. Then, out of the blue, as I drive, the doors will lock and the guages will start working. I've checked the fuses.
You have to remove the under hood fuse / relay box and disassemble , check for broken / corroded wires in the harness plugs at the bottom and broken solder joints at the board. I have repaired many of these for the same problem. hope this helps
