I finally got my service manuals and tracked down the problem.It seems that the master switch has failed.I jumped across the plug and the blower motor came to life and everything works fine.Now i need figure out where to get a switch.Any ideas?
Master switch? Picture please....is there a part number on it?

The other option is a junkyard or the derby guys.
