Dashboard gauges dont work after crossing jumper cables.

sounds like a neutral position sensor on your gear box . this is first thing I would check.

ALWAYS check the body grounds first. Ground to the dash gages could be faulty, dirty, or just not tight enough to make a good connection.

The instrument cluster in this van is really a computer display and it has malfunctioned. This is a common complaint on this van and you must remove the cluster and have it rebuilt to cure the problems. Check the WEB for repair sources. They can also provide complete instructions on removal free of charge.

^ have no idea what they are talking about

lose connetor behind dash board.

Does the van run. If it does you may have a bad ing. switch

check the ground on the computer the wires sometimes come loose and cause this

These vehicles seem to have a problematic short, my grandfather has the same vehicle with the same problem, i found the short under the carpet on the driver side of the vehicle, under the gas pedal, sometimes wires can crack and break.

Its sure sounds like the alternator to me. If you have a battery charger charge the batteryup for an hour or so start the van and if you have a volt meeter put it on th e battery and see what it reads should be around 13.6 volts make sure everything is off at this time heater radio ect if that reads around 13. volts now turn on the light s radio heater and 4 way flashers and see if the voltage starts to drop if it drops below 13. volts the alternator is bad also if the battery is over 4 years old replace it.If all elese fails take it to a well know repair shop

yes check belts ..and the cause .. a frozen water pump or other accessory that is turned by the belts frozen ... then advise me
