Question
The lights were left on all night and battery was dead in the am. Jumped to start, all seemed ok. Later trie the ac, no cooling. Checked the 3 designated ac fuses in glove box, all ok. Help

Answer
The battery must be on its way out(they last at MOST 5 years),when you turn the ignition off the lights shut off all except the parking lights.You do have other systems that run all the time clock,radio,etc.It has nothing to do with the ac.It probably needs to be recharged
