Hello, first thing I would look at is your electrical system. If your battery is drained, then there is likely a good reason - such as a charging system that has failed. Test your charging system and troubleshoot the cause.
Sounds like the alternator has failed. May need to replace battery also.
Would also look at Codes for the evaporator system. Could use diagnostic and smog test. Would be glad to offer 773 549 7777
