Hello everyone,

Last week my radiator blew on my r129 from 95. I got it fixed friday and everything was fine. Yesterday I found out that the A/C only blows out hot air everything else works just fine.

I read that I could diagnostic the issues my self and so i did. My problem now is understanding what they mean.

My readings are:
73 A/C compressor signal (OC)
07 Evaporator temperature sensor (OC)
70 Auxilian coolant pump (OC)
31 Automatic A/C Monovalve left (SC)
71 Automatic A/C Monovalve left (OC
73 A/C compressor signal (OC)
74 Auxiliary fan signal 2nd stage (OC)
75 Auxiliary fan signal 1st stage (OC)
end

Do anyone know what these readings mean and what might be wrong with my A/C?

Thank you very much for your help!

Can no one help?

I had a problem with my radiator that blew up a week before I noticed that the A/C did not work. Can this have harmed any components?

I also did a temperature read on the sensors. The outdoor temperature was 72:

02 = In-Car Temperature Sensor : 78
04 = Outside Temperature Sensor 72
06 = Evaporator Temperature Sensor 76
08 = Heater Core Temperature Sensor 76
12 = Engine Coolant Temperature Sensor 76
14 = Temperature Selector Wheel Setting 72
18 = Vehicle Speed Signal (km/h)
20 = Soft Top OPEN ("u") or CLOSED ("o") o
22 = Power Supply Voltage 11.8
83 = Not Used
84 = Blower Motor Voltage 11.8
