My Lexus GX 470 AC Emits Hot Air But Cools Only On The Passenger's AC Vent by kbright911(m): 12:35pm On Sep 13, 2017
[color=#770077][/color] I bought my Lexus GX 470 2007 model late October last year and everything was good, but of recent I've noticed that the AC has stopped cooling and blows hot/warm air inclusive the rear AC vents. But the passenger's AC vents still cools.. Please what could be wrong with my SUV's AC system. Professional advise needed please.

Check your dual climate button, if it is ON.. Put it Off and adjust the driver side temperature... If that doesn't work.. Wait for advice from the professionals

Does the dual climate control still works?
try switching to warmer air on both sides if this works switch back to cooler air. If the drivers side still blows warm air, then it probably is the actuator that operates the vane (btw cool and warm air) is stuck on the warm air on the drivers side.

There maybe other causes but I had a similar experience and that was the culprit, the technician serviced the plastic gear system and greased it before it worked.

3 major culprits.

1. low refrigrant
2. faulty blend boors in the air actuator
3. faulty dual climate control.

being a toyota, my money is on option1, hook a pair of manifold guages to the ac hi n lo side ac ports, they should be 30~45 lowside , and 180~240 hiside

If dual regulator is fine then that means refrigerant gas is low, have it vacuumed and refilled, also add Uv dye to the system so that point of leakage can be traced.
