Hello everyone -

RE:  '87 Vanagon Syncro

My headlights were working just fine, and then died for no apparent reason.

Description of events leading to failure:
1)  Vehicle started and headlights were switched on.  Lo-beams came on as normal.
2)  After approximately 1 minute, the lo-beams dimmed momentarily, then back to normal.
3)  After approximately another 2 minutes, the blue "hi-beam" lamp came on without any human intervention.
4)  Attemt to turn off hi-beams resulted with no change.
5)  The headlights turned-off.  (Do no know if it was at the same time as #4 above or delayed.)
6)  Ignition was turned off.  Restarted vehicle after approx 1 minute.  The headlights came on momentarily and then went off.
7)  Headlights are dead!  Headlight / hi-beam switches have no affect.

I checked all fuses in the fuse box for continuity . . .all's fine.
I reseated all of the relays in the fuse box.

Current status:
A)  Igniton: off          Light switch: off
      Results:  Blue hi-beam lamp comes on when hi-beam lever is pulled, goes off when released.
                      Hi-beams: stay off          Lo-beams:  stay off

B)  Ignition: off         Light switch: on
      Results:  Same as #1 + relay in fuse box position10 clicks on/off with blue lamp.
                      Hi-beams: stay off          Lo-beams:  stay off

C)  Ignition: on         Light switch: off
      Results:  All same as #1.

D)  Ignition: on         Light switch: on
      Results:  Blue hi-beam lamp is always on.  Hi-beam lever makes no difference.
                      The relay in fuse box position 10 cllicks once when ignition is turned on.
                      Hi-beams: stay off          Lo-beams:  stay off

Does anyone know how to fix this problem?   . . .Could the relay be bad?

Thanks for your input.
