I have found out the certain Nissan/Infiniti SUV models had the fan wired wrong from the factory. Does this apply to my 2009 QX56? If so can I use the key on /press the door jamb switch 10 times to put it in test mode so that it will check my condensor fan in the process to see if it works and is spinning in the push fresh air in position instead of pulling hot air from engine bay through the radiator method?
I assume this system is similar with most other AC systems and the condensor fan will not engage if low on freon, it cools but does not get cold, the high side line where freon is added is the one closest to driver side firewall i presume, it should be ice cold to the touch, not just slightly cool like mine is.
I will try getting a can of 134a today and charge the system a bit and see if it gets colder and the AC condensor fan will kick on hopefully.
