    Auto HVAC Fault code

    Hello,
    I have a 1993 Audi b4 80 2.3e FWD Auto trans. Two moths ago, I started experiencing weird issues with the air conditioning. Air conditioning works fine, but the heater isn't working. The VAG-COM scan gives me the following codes:


    Address 08: Auto HVAC Labels: None
    Part No: 8A0 820 043 B
    Component: Klima-Vollautomat D51
    Coding: 00050

    1 Fault Found:
    00799 - Coolant Temperature Sensor (G110)
    30-00 - Open or Short to Plus

    Could anyone help me with this issue? Would greatly appreciate it.
