OK so procedurally what I think I should do is: 1) Remove the cowling and instrument pod to gain access to the switch. 2) Remove the two leads (two wires each) from the brake master 3) Clean the heck out of all the conectors, and apply dialectic grease 4) Check for continuity between those wires and the brake lights in back (I've stripped one oif the brake wires so I can test this) 5) Pray that it works Sound right?

There is no MECHANICAL swich for the brake lights. There are instead TWO hydralic switches on the side of the brake master cylinder. Either of these switches will make the lights work, but if only one of the switches works, but not the other, the Brake Warning switch will also light up. At least in theory! These switches rarely go bad - usually the connectors get knocked off, or just loose... ...gee, isn't that a rare thing - wiring faults on a Vanagon! ;-) > >1993 Bonneville > > > > > > >
