Climate Control acting weird

[seneka716]

2000 Buick, already checked for codes but nothing there. Climate control comes on when put on "auto" but while driving, will suddenly turn itself off. My brother is a mechanic for 25+ years but hasn't handled Buicks for some time (mostly BMW and Mercedes) - needs some ideas on what to check for. He thought maybe the module, but in reading these posts, I'm questioning if it's the ignition switch? Anyone else have this problem? I'm also experiencing a non-working cruise control at the same time - light comes on and immediately goes off on the dash. Thanks for any help!

Go to the Tips and Maintenance Section of the forum. There is a good article about the Climate Control in there. That's one of my next projects!

My 2001 Regal A/C would turn off along with the cruise control. My fix for my car was the new ignition switch.
