    Driver side A/C blows HOT air, while passenger side cools OK, shutting eng off and restarting cures problem, has happened a few times. Saw a couple of threads but not clear of what problem is. Someone mentioned "DUCT MOTOR" but could not find in GM parts. Would appreciate some further help.

    Ive seen a bad battery do this also. I know its weird but either a weak cell or corroded connections have played many a tricks on people. Never role it out, lol.
