AC and electric window malfunction

My 1993 LeBaron LE sedan, AT, 300cc engine, front wd has about 130,000 miles on it, and the AC / heater blower and the power windows both quit on me at the same time a couple of weeks ago.

Because I am on a low fixed income and I'm going back to college next week, I need to fix the problem myself and NOW, or the Princessmobile will be dangerous to drive when winter weather fogs up the windshield.

PLEASE HELP! : :

Thanks.
