Thanks for the advice.  I cleaned electrical connections today.  The windows quit because wires going into plugs under driver's seat had corroded completely off.  Rewired & windows work!  All the electrical contacts under the hood were corroded.  Also, I figured the contacts in the wiper switch must be corroded too so I flipped the switch on & off about 50 times fast & the corrosion must have worn off because the wipers now work.  I'll check the ignition switch tomorrow.   
  
Thanks again for your help
