I found the following description on the web, this covers a bunch of the questions I was going to ask...

I own a 2000 Silo and wondered the same thing and do see some GM vans with this problem.

When I bought mine I also bought the Haynes Repair manual (1997 thru 2001 all models GM) #38036 to learn how to fix this and a LOT of other components in/on the van.

For $20 it's worth it.

To answer your question: If the wipers stop at the position they're in when the switch is turned off (Fail to park), disconnect the multi-function switch electrical connector. (This is located under the dash next to the firewall and steering column)

If the wipers now park, replace the multi-function switch. If the wipers still do NOT park, check the wiring from the wiper motor to the switch for a short circuit. If the circuits are good, replace the wiper motor.

Note: There are other adjustments needed for proper operation than just bolting and new motor on.

You can have a look at this manual at any automotive parts supply store.

The coolant level sensor is located on the radiator. If you are looking at the engine from the front of the car it will be on the left side. There will some kind of clip holding it in the radiator. Removed the clip and pull the sensor out. You will lose coolant so try to swap it out quick or drain some of the coolant out. Once new sensor is installed, install clip to keep the sensor in place and reconnect the wires to the sensor. Crank the engine and make sure the coolant level is full. This should correct your problem.

Sadly no, there is no fuse or bulb to replace. You either have to send the instrument cluster out for repair or replace it with a new unit from the dealer. You could also obtain a serviceable one from a salvage yard. Most shops should be able to replace the instrument cluster or advise who can repair it.

You're either looking at a short in the wire that goes to the fuel sender, or a bad fuel sender. If it was just a broken wire, it would read empty instead. The fuel sender is a permanent part of the fuel pump, so that has to be replaced as a unit.
