Instrument cluster defect?

Hi, I have W450, 600ccm, gasoline, 40 kW, year 2000 and I have made a diagnostic with my SDS on Dell630 laptop today. The reason for a diagnostic is because I cannot see ambient temperature on the display. In addition AC is not working, the switch shows two red lights, however refrigerant temperature does not drop. Could these two issues be related ? It seems that something is wrong with instrument cluster. Namely, diagnostics shows open circuit for ambient sensor. Additional... Instrument cluster defect?
