A/C will not turn on and diagnostic read CC-007D and CCM-000A. on 2004 Volvo S40

I took my 04 Volvo S40 to a Volvo expert to find out why my car's A/C would not go from off to on. He scanned the vehicle with VCT-2000 diagnostic and found code CC-007D and CCM-000A. He recommended replacing the evaporator temp sensor and the damper motor. Is this correct or do I just need to fix the A/C switch?
