Omega B – ECC – Heating gets warm only left

Good morning, all I have read this message completely, but find no solution. In my case, the following is the case: I have an Omega B with automatic air conditioning but the heating is only warm on the passenger side with me (i.e. driving side) everything ice-cold itself remains the seat heating. What can that be?? Also the fan or the blower like this is only delayed. Directly after the reset car and off pressing they also go. On Eco function also does not change S. How do you possibly have to flush something? Many pictures or so where does the termostat sit if the hood is damaged?? Or in another forum son servo is described in the footroom? What can I do?? If I turn on the climate, for example, to make my windshield free of fog on the right side Warm (hot) air Out. Left side all ice cold footroom Left disc and just left air outlet. With Hi and Lo nothing changes. LG ANDY
