Thank you all:
Thanks for all the good tips I did not remove the cabinett, traced it to
a problem with the switch.  The back of the sswitch had two burnt
connections with fried wires and all.  I have removed the switch and am
now looking for a replacement. Would also like to find a wiring diagram
as I did not mark the wires when I removed them ( it was hot I was dumb
:) ).  Any one no where I could obtain a switch or diagram?  Tried
GoWesty  online but they only have for an 86-91 and mine is an 84.
