Good day fellas,
I recently picked up a 01 Montero limited. front ac works rear does not. I hear the blower in the rear but no air is coming out. I've tried searching online and can not seem to find the problem. Hopefully you can guide me to the right direction to start.
Thanks in advance.

 

Check the status of the refrigerant in the system. If you have pressure, but no pressure change when AC is turned on - you have problem with ether compressor, compressor clutch or with controls somewhere along the line before compressor. If you have no pressure in the system - you have a hole somewhere and you've lost all refrigerant. In that case AC system will not turn on to prevent damage to itself.
