A "1" means no codes. I don't think the battery voltage is an issue here, but you can get the controller to display its supply voltage if you want to check it as explained here.

When the A/C is not blowing cold, is the compressor off or on?
Compressor ON, with no air bubbles visible in sight glass .... Dial @ LO .... rheostat works fine...But, no condenation, ie; water dripping when parked... just plain NO COLD!
Interestingly enough now this problem with the control unit, only after winter storage.
The voltage is 11 point something which is correct as I know it, but I could be wrong. ;~0
I think I checked that when I did the test. I think now the batt is ok. I now wonder if it's the ignition switch! If only some of the contacts are functional it might cause this problem as well. But then again, would the control unit come on at all???
