Services Performed
- DURING THE DIAGNOSTIC PROCEDURE, WE FOUND THAT THERE WAS NO POWER BEING SUPPLIED TO THE A/C COMPRESSOR. WE PERFORMED A THOROUGH INSPECTION OF THE ENGINE COMPARTMENT, INCLUDING ALL RELATED WIRING HARNESSES, ELECTRICAL CONNECTORS, FUSES, AND RELAYS. THROUGH THIS PROCESS, WE DISCOVERED A SECTION OF THE WIRING HARNESS THAT HAD BEEN DAMAGED AND SHORTED OUT, WHICH WAS PREVENTING PROPER VOLTAGE FROM REACHING THE A/C COMPRESSOR. WE REPAIRED THE DAMAGED PORTION OF THE HARNESS USING THE FACTORY WIRING DIAGRAM TO ACCURATELY TRACE AND IDENTIFY EACH WIRE'S ROUTING AND FUNCTION. ONCE THE REPAIR WAS COMPLETED, WE REASSEMBLED ALL PREVIOUSLY REMOVED COMPONENTS, SECURED THE HARNESS, AND RETESTED THE ELECTRICAL SYSTEM. AFTER VERIFICATION, WE CONFIRMED THAT POWER IS NOW BEING PROPERLY DELIVERED TO THE A/C COMPRESSOR, INDICATING THAT THE ELECTRICAL ISSUE HAS BEEN SUCCESSFULLY RESOLVED. FURTHER TESTING OF THE A/C SYSTEM CAN NOW BE PERFORMED TO COMPLETE THE REPAIR.
- CONTINUED OUR DIAGNOSTIC PROCEDURE TO IDENTIFY THE SOURCE OF THE A/C SYSTEM LEAK. WE BEGAN BY PRESSURIZING THE A/C SYSTEM WITH NITROGEN TO TEST FOR LEAKS AND OBSERVED THAT THE SYSTEM WAS UNABLE TO HOLD PRESSURE, CONFIRMING THE PRESENCE OF A SIGNIFICANT LEAK. WE THEN PERFORMED A DETAILED INSPECTION OF ALL MAJOR A/C COMPONENTS, INCLUDING LINES, FITTINGS, CONDENSER, EVAPORATOR, COMPRESSOR, AND VARIOUS CONNECTION POINTS. DURING THE INSPECTION, WE DISCOVERED OBVIOUS SIGNS OF REFRIGERANT LEAKAGE COMING FROM THE AREA AROUND THE A/C PRESSURE SWITCH, INCLUDING RESIDUAL DYE AND OIL TRACES. THIS INDICATES THAT THE A/C PRESSURE SWITCH IS THE LIKELY SOURCE OF THE LEAK. WE WILL RECOMMEND REPLACEMENT OF THE DEFECTIVE COMPONENT, FOLLOWED BY A SYSTEM EVACUATION, RECHARGE, AND FINAL LEAK TEST TO ENSURE FULL FUNCTIONALITY AND RELIABILITY OF THE A/C SYSTEM.
- REMOVE ALL NECESSARY COMPONENTS TO GAIN PROPER ACCESS TO THE A/C PRESSURE SWITCH. SAFELY DISCHARGE ANY REMAINING REFRIGERANT FROM THE SYSTEM TO PREVENT DAMAGE OR INJURY. CAREFULLY REMOVE THE DEFECTIVE A/C PRESSURE SWITCH AND INSPECT THE MATING SURFACE AND CONNECTOR FOR ANY SIGNS OF DAMAGE OR CONTAMINATION. INSTALL A NEW A/C PRESSURE SWITCH, ENSURING A SECURE AND PROPER FIT. REASSEMBLE ALL PREVIOUSLY REMOVED COMPONENTS AND VERIFY THAT ALL ELECTRICAL CONNECTIONS ARE PROPERLY SEATED. MAKE ALL NECESSARY ADJUSTMENTS TO ENSURE CORRECT INSTALLATION.
- FLUSH THE ENTIRE A/C SYSTEM TO REMOVE ANY CONTAMINANTS, DEBRIS, OR RESIDUAL OIL THAT MAY BE PRESENT IN THE LINES OR COMPONENTS. THIS IS A CRITICAL STEP TO ENSURE THAT FOREIGN OBJECTS DO NOT CIRCULATE THROUGH THE SYSTEM AND CAUSE DAMAGE TO SENSITIVE COMPONENTS SUCH AS THE A/C COMPRESSOR, CONDENSER, OR EXPANSION VALVE. UTILIZE A PROFESSIONAL GRADE A/C FLUSHING SOLVENT AND COMPRESSED AIR TO THOROUGHLY CLEAN THE SYSTEM. FOCUS ON FLUSHING OUT EACH INDIVIDUAL LINE AND COMPONENT, ENSURING THAT FLOW IS CLEAR AND FREE OF OBSTRUCTION. INSPECT FOR ANY SIGNS OF EXCESSIVE CONTAMINATION DURING THE FLUSHING PROCESS. AFTER THE FLUSH IS COMPLETE, ALLOW THE SYSTEM TO FULLY DRY, THEN REASSEMBLE ALL COMPONENTS USING NEW SEALS OR O-RINGS AS NEEDED. FOLLOW UP WITH A VACUUM PROCEDURE TO REMOVE ANY REMAINING MOISTURE, AND THEN RECHARGE THE SYSTEM WITH THE CORRECT TYPE AND AMOUNT OF REFRIGERANT. VERIFY SYSTEM PERFORMANCE AND ENSURE ALL COMPONENTS ARE OPERATING EFFICIENTLY AND FREE OF DEBRIS.
- PERFORM A VACUUM PROCEDURE TO REMOVE ANY MOISTURE OR AIR FROM THE SYSTEM. RECHARGE THE SYSTEM WITH THE CORRECT TYPE AND AMOUNT OF REFRIGERANT. TEST SYSTEM OPERATION AND VERIFY THAT THE REPLACEMENT HAS RESOLVED THE ISSUE AND THAT THERE ARE NO FURTHER LEAKS PRESENT.
