Recently the car ignition was left on overnight. The battery was dead. the car was jumped and started fine. on the dash the rear wiper, the intermitent wiper, the recyl. air, and the A/C button were all flashing. Now the A/C wont turn on. it will only blow hot air. now matter what temp the thermostat is set at it will only blow hot.

Fully recharge the battery, disconnect it for about five minutes, and then reconnect.
