Hi Everyone

I have a weird problem on 2002 E430 102k miles with my AC.
Let me start with AC Control Unit -
Most of my buttons are not working except: 1-speed of blower 2-window defroster 3-windshield defroster/heater

EC button has red light on but cant be turn off. Any other button is not responding.
AC is set to LO on both sides.

Compressor is not kicking in at all, i have checked presure on L and H and here are the results:

Low - it shows 70
High - it shows 70
which i think it is right since the compressor is not working.

All FAN works

I have tryied to refefill freon but i think presure on low is too high and can not get recharged.

What can be the reason for this malfunction? Would it be bad compressor, AC Control Unit or ECU computer? or maybe something else.
