Check the AC unit under the hood is it working? or trying to? is its fan belt on properly ? has the refrigerant ( like Freon) been checked ? is it too low ? (a likely cause of your problem) if too low recharge the Freon after looking for any hose leaks. Check a notional chain auto parts store or on line for kits to recharge or go to an auto air conditioner shop or the dealer.
