The dimmer switch is very hard to remove (access is tight). That is why I am having you test ground the black wire with the white stripe. Did you temporarily ground the black wire with the white stripe on the cigarette lighter BULB wires as I requested? The shift indicator lights are part of the dimmer circuit so it make sense that they are out too. There should not be any more fuses in the remaining circuit. The only fuse in the dimmer crcuit is the one under the hood protecting the entire marker light/gauge light system after power leaves the marker light relay. There are no fuses behind the glove box. Since you said your brother has a tester, pull out the little bulb on the cigarette lighter bulb socket and see if either contact inside the socket gets power when the marker lights are turned on.
