Common problems why the rear air is not working?

Hello, is your rear air just not blowing, or is it blowing hot air? If it is not blowing, be advised that the rear of the vehicle utilizes a separate blower motor fan compared to the front of the vehicle. This blower motor is located on the driver's side of the vehicle just behind the driver's door, behind the "b-pillar" trim. If this motor is not turning on, it could be the fault of the motor itself, the wiring, a relay or the switch that turns it on. If you are getting warm air in the rear, you could have a problem with the rear air conditioning evaporator expansion valve, a problem with refrigerant charge due to a system leak, or even perhaps a weak compressor. As you can see, there are a wide variety of causes, and so you may need to enlist the help of a local shop near you with techs that can help!
