What does the flashing light on my auto temp controller mean?

I know I saw this in my service manual, but I can't seem to find it again. My AC won't blow cold air, but the blower works fine. Also, I don't seem to have much hot air on heat either, but then I can just roll down the window for that ;) Thanks in advance...

I remember reading about that in the owners manual. I cant remember what it was exactly, maybe low freon. I know it means there is a problem. If you have owners manual look in there. When I get a chance I will check. Guy

I know when mine began to blink it was indicating low freon.......ended up being my AC condensor.

This link has the diagnostic procedure for troubleshooting the C68 Climate Control system. Look for a 09 code "Low Freon"

I believe the explanation is also found in the owners manual. Suspect you have low freon. As stated above, pull the code and suspect you will find good ole 09.

Thanks for the help guys! The previous scum that owned my car did not take good care of it, or any of it's belongings, therefore I currently have no owners manual. That link is cool, thanks c4cruiser!! :chevy :flag :cheers:
