1997 Dodge Caravan Guages and Automatic Door locks do not w

Bad cluster is the most common that I have seen and repaired
have to remove cluster out of the van
inspect the pins where the wiring harness plugs in,
also have to remove the board and inspect the pins solder to the board
they need to be soldered back on the board
so you have to remove the cluster remover rear board and solder the pins back on the board
that should solve the buss problem

To remove the whole transmission with ABS the ABS pump must come off or be disconnected to its mounting and strapped up. Some had a ground wire involved that the ABS system used. The Crank sensor, also could be causing both ABS and Check Engine lamps since it easily damaged if not removed and replaced. A spacer(new) on it is for installation at the correct depth. A green felt spacer. The engine wiring hangs when the powertrain is dropped at an angle to reach the upper trans bolts. If any of these things, especially the crank sensor are causing this problem the symptoms are immediate, and happen immediately on starting. The transmission and ABS module use this sensor as does the tach, and speedometer.
So check every fuse in both power centers first, then reckeck the items I spoke of. Reset the systems with a scanner and after this problem occurs rescan for any hard code. Really depends which 6 cylinder. If a fuse blew, the data link connector will have an open circuit and read no bus. The wiper multifunction switch may or may not have something to do with these things. These things happen on this job especially with a 3.3 or 3.8L engine.
