I repaired and tested this members climate control unit successfully. However he had a blown FSR (Final Stage Resistor) which is located above the gas pedal. These faulty FSR's are common and sometimes people misdiagnose their problems and point the finger at me. A system must be 100% operational for my climate control unit to work properly. In no way was I ever vulgar or offensive. I pride myself with customer service and stand behind my work to the fullest.
