What are these switches in my 97 American Cruiser?

Switch 1: Minidisc player/recorder
Switch 2: Cassette deck
Switch 3: DAT deck
Switch 4: DBX Type II decoder for cassette deck playback

That's odd. I don't have a minidisc, DAT deck or DBX decoder. I have a cassette deck in the radio unit but neither the radio or the cassette deck work.

generally those are used for auxiliary lighting. they are the same ones used in conversion vans. could be rope type accent lighting or other types of lighting. have any lights that don't work? try those switches along with the switch on the light or they could be burnt out. can be used for other accessories also. funny they are not labeled. could unscrew the switch panel and see if they are all even wired up.

Try this Google search. "american cruiser van conversion wiring diagram"
Came up with a page of drawings one could match yours.

Thanks for the suggestion about rope lights and other accessory lights, shastagary. I found that two of the switches control rope lights along the floor and above the bed. I had not noticed them when I tried it out before. This time I looked more closely. Still trying to figure out the other two switches. I looked over the wiring diagrams and didn't see anything that looked like it was for an American Cruiser. I have the wiring diagram or the Dodge van (Haynes) but not for the conversion. But thanks for the suggestion and effort, 1995brave.

I have nothing like that on my 1999 American Cruiser, but I also don't have any fiberglass on the inside like it appears you do. My porch light switch and bathroom light switch are located in strange places. Perhaps that's what the other two switches are for!
