Howdy,

I have a 1991 Chevy C1500, and have noticed that that HVAC control panel gives me information for troubleshooting. For example, when refrigerant pressure is too low, the AC indicator on the panel will go from solid to blinking. Pretty nifty! I have more issues with the AC that need fixing, however.

Is there a list of all the different warnings or indicators that might be shown here? For example, the small arrows on the left side of the panel are all blinking on my display. I know there is some kind of error with the blowers or paddles in the dash (air only blows through the defroster vents!), but is this indicating something specific?
AC Controller, with the AC indicator and arrows on left side faintly visible.

Thanks!
