    P0128 - Coolant Temperature Below Thermostat Regulating Temperature

    A search is indicating that it could definitely affect the AC

    Why not address the code?
    There are NO other codes -
    P0128-THERMOSTAT RATIONALITY - coolant level in radiator not tank, thermostat issue, AAT issue

    Many codes will effect other systems - a protection logic... Why you always SCAN.

    AC is a priority!!
    As I said check fluid level - replace thermostat - do not use lower rating T'stat!

    Do you have a Ambient temp sensor? in case the above does not solve issue...
