IHKR problem

[Kamz e34]

Hello everyone
My e34 heater control module is not switching from hot air to cold air. The heat is always on an no cold air when i switch it to cold. The heater valve is working properly but there is no power to the switch of the heater valve. Is the heater control module the problem? Can it be repaire? I have the IHKR

First of all check the heater valve, if it is really working and pulsing, without power it is fully open. It could be stuck in open position https://www.youtube.com/watch?v=4lXgpmjbJbE

if that is ok, check the wiring diagrams

Yes it is working, i got it repaired and it's 100% working but there is not power to the connector.
