If you have been disconnecting your battery, I would not worry about it... It will probably go away after a longish drive.... But make sure your cables are tight...

Mine has done that several times when I had the battery off (1994 sse) and it always comes back. You will find that the A/c does not work while it is in that state. But it seems to figure out that all is well after a while and comes back... (unless of course, all is really NOT well )

I would take a longish drive and run the a/c through various cycles...A/c and no a/c... run the temp up and down in both... toggle external temp on and off, put both defrosters on and off etc....

In my most recent battery-off case, the A/c came back and the blinking stopped but the lamp monitor says a brake light is out, even though none is... First time that happened so I watching it. and trying to see if I can find something to read about it...

Is it blowing hot air now like hotter than hot, even with the system off?
Mine did that once, I fixed mine by cycling off then auto I did that a few times and it stated working again. I haven't had another problem in over a year since.

Just a thought.
