Services Performed
- Performed full A/C system evaluation. Recovered only 0.72 lbs of R-134a; recharged to full OEM spec of 0.99 lbs. With system fully charged, observed abnormal pressure readings: low side held steady at ~60 psi, high side ~190 psi at idle (88°F ambient). Vent temperature remained ~70°F. A/C clutch engages and is properly commanded by ECM; relay and pressure sensor functioning. Despite correct signal and refrigerant level, compressor fails to create proper pressure differential. Compressor internally weak or control valve stuck — confirmed common failure pattern for this vehicle. Recommend replacing A/C compressor and flushing system.
- Evacuate & Recharge the A/C system. Fill A/C system to factory specifications.
- Card Fee
