Strange climatronic problem

[ivarf]

Im trying to figure out what could be wrong with a Skoda Yeti 2011 with dual zone climatronic.
Temparature values for all four outlet sensors (footwell and dash) on bouth sides shows about 75 degress C all the time.
Feed voltage for all sensors are at 5V, ground is ok, and sensors set fault code when disconnected.
I tried change sensors, climatronic panel(computer), tried disconnect air quality sensor and refrigeant pressure sensor. Tried disconnect all
four sensors trat reads erratic and just reconnect the new one. Same result.
Readings of evaporator temp, in car temp, coolant and ambient temp sensors are reasonable
Climate system blow ice cold air all the time till the temp controls are turned all the way to hot and overrides temp. readings.
Anyone have seen this problem before?

Thx in advance!

No logical answer.

any fault codes?

only logical thing would be water in ambiance sensor outside

beyond that can only be loss of supply to computer or a faulty shorted motor

if easy can you run blower motor off separate battery on floor incase
sending bad signal back
