99 GTP Climate Control not adjusting

I have a grand prix with digital climate control and it recently stopped having the ability to set a temperature. It strictly blows out hot air right now even under Auto setting. I am able to kick on my a/c when its above 40 degrees though. Actuators?

Is the maintenance man icon on on the climate control head unit? You can try the CJ2 ACC diagnostics but it sounds more like the head unit.


When running the A/C do the temp controls work?
