B2644 Code Nissan:
The B2644 code in a Nissan vehicle indicates that there is an issue with the electric compressor output line. This means that the signal from the electric compressor is not being received by the vehicle’s computer, which can cause problems with the air conditioning system. The electric compressor is responsible for compressing the refrigerant in the air conditioning system, which is then used to cool the air that is blown into the cabin. If the output line is open, it means that there is a break in the circuit, which can be caused by a faulty compressor or a wiring issue. To fix this problem, the compressor and wiring will need to be inspected and repaired or replaced as necessary.
Signs and Symptoms of B2644 Code in Nissan
