How does the front blower relay work on a Nissan Rogue?
The front blower relay controls the flow of current to fuse 17 and 27 in the Fuse Block (J/B). The relay is grounded when the ignition switch is in the ON position. The BCM receives the fan ON and A/C ON signals from the A/C auto amp. and sends a compressor ON request to the ECM.
How does the air conditioner work in a Nissan Rogue?
A/C auto amp. A/C auto amp. controls front automatic air conditioning system by inputting and calculating signals from each sensor and each switch. The air mix door controls the mix of hot or cold air that enters the ventilation system. It is controlled by the A/C auto amp. based on the position of the temperature dial.
How to diagnose a / C switch assembly in Nissan Rogue?
Diagnosis of the A/C switch assembly can be performed using the CONSULT. There is no selfdiagnostic feature available. The variable blower control controls the speed of the blower motor by controlling the ground circuit of the blower motor.
How does the temperature sensor work on a Nissan Rogue?
In-vehicle sensor measures temperature of intake air that flows through aspirator to passenger room. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.
The front blower relay controls the flow of current to fuse 17 and 27 in the Fuse Block (J/B). The relay is grounded when the ignition switch is in the ON position. The BCM receives the fan ON and A/C ON signals from the A/C auto amp. and sends a compressor ON request to the ECM.
How does the a / C system work on a Nissan Rogue?
The A/C switch assembly controls the operation of the A/C and heating system based on inputs from the temperature control knob, the mode switches, the blower control dial, the ambient temperature sensor, the intake sensor, and inputs received from the ECM across the CAN. Diagnosis of the A/C switch assembly can be performed using the CONSULT.
How does the air mix door work on a Nissan Rogue?
The electrical resistance of the thermistor decreases as temperature increases. The air mix door controls the mix of hot or cold air that enters the ventilation system. It is controlled by the A/C auto amp. based on the position of the temperature dial. The air mix door motor LH receives position commands from the A/C auto amp.
Where is the a / C control relay located?
The A/C compressor relay is located inside the IPDM and is not serviceable you will need to replace the unit. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
