[Mgs] No Turn Signals

Just to put an end to this thread, the turn signals work now.  I replaced
the hazard switch and like magic the turn signals started working again.
Added bonus, the hazard light work now too!  ( They never did since I have
owned this car over a year now)  I guess the switch was somewhat broken
from the start.  Just not broken enough to stop the turn signals. Woohoo!
