The A/C is not working. The blower is blowing. I push the Auto button and it goes right back to econ. Does the system just need recharged or is something else wrong? Any ideas?

Typical symptoms for low freon, but don't just try and charge it, there is a leak somewhere and the system should be professionally serviced.

I service my own. The problem wasn't low freon. I unhooked the battery cable for a while and something must have reset. It's working fine now...go figure.
