My Vanagon is due back later this week for final parts to be replaced on braking
system.  I noticed that I no longer have rear brake lights.  Everything else on
the rear light clusters works so I suspect that the when the master cylinder was
replaced, the connection to the brake lights was not put on correctly.  Is there
an easy way to get to the switch without taking the instrument cluster out?  I
remember doing this on my '84, but on first try there does not appear a way on
the '91 to see the if the wires are connected correctly.  Any help on this would
be most appreciated.

Thank you,

John
