I think your Dolphin may have a fuse panel under the access panel on the top of the dash on the drivers side, at least our 05 Dolphin did. Check fuse #23(Frt. Park), Fuse #17 (Marker Lps), Fuse #9 (Pk.Lps) and all the rest if those didn't turn up anything.
Also, check that all the wiring plugs on the block next to it are securely plugged in.
