I was having the problem of no cold air ( really warm air) blowing on the passenger side of my 2005 AV with electronic climate controls. Drivers side was colling fine. Read a post that suggersted disconnecting negative terminal for a few minutes which I did. After reconnecting, and starting, cold air blows on both sides after an engine start, but only for 30-45 seconds, and then heated air starts blowing from all vents and stays that way! Bummer! I'm in Texas - it's hot! Help! Thanks.
