  Summary

  Certain GV70 (JK1) vehicles may experience an intermittent A/C inoperative condition when the engine is started after the air conditioner has been operated with the ignition switch in the ON position. During engine cranking, a temporary low-voltage condition may cause the blower motor protection logic to activate, resulting in the A/C system turning OFF and remaining inoperative until the vehicle is restarted.
