Symptom Chart: Climate Control - Dual Automatic Temperature Control (DATC)
NOTE:
Some Powertrain Control Module (PCM) Diagnostic Trouble Codes (DTCs) may inhibit Air Conditioning (A/C) operation. If any Powertrain Control Module (PCM) Diagnostic Trouble Codes (DTCs) are retrieved, diagnose those first. Refer to the Powertrain Control Module (PCM) Diagnostic Trouble Code (DTC) Chart.
Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. REFER to: Diagnostic Methods .
