The temp sensor output to channel 5 (the outside temp sensor that is in
front of AC condenser) is faulty. It is giving a reading ("142") that says
it thinks it's about 5 Celsius. This faulty reading, IMO, will keep your AC
compressor from coming on. Replace it (the sensor).

The channel 4 reading seems too high, but considering the test conditions,
it may be OK. It won't affect your AC.

'91 200q  parked where it really _is_ 5 Celsius today :-(
