The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in the PI.
Condition/Concern:
Vehicle's RKE may be inoperative when the blower motor is left on "HIGH". This can only occur when the vehicle is left running, the blower speed in the "HIGH" position and the doors manually locked. Although operating the vehicle in this manor is not recommended, customers in colder or warmer climates operate the vehicle this way to reach a comfortable temperature in the cab of the vehicle prior to driving. EMI from the blower motor in the "High" position may affect the RKE operation.
Recommendation/Instructions:
Placing the HVAC blower fan to a lower setting prior to leaving and locking the vehicle will correct this concern.
Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
