On my 1992 GTR air only blows out the defrost vents now and cannot be changed to the Dash vents. The display mode changes but not the vent actuator. All other functions work including AC.

Currently looking for a "heater blowing cold" fix. My A/C works fine, seems like nobody cares if the heater works through haha

Will this tell me why the ac stopped working? 90’ R32 GTR

Currently have a 1995 Skyline R33 in this car the front windshield defrost means “AMB” when it comes to changing input during test, complied with the test, all motor/actuator do their job, absolutely 0 faults on the panel however, every time I select the mode on the ac panel nothing happens, I’m currently blowing ac to my face which is good but on humid mornings, can’t direct air to get defrost on front windshield, what could this be ? I removed every actuator to test outside & apply new lubricant & my AC works ICE cold and heat.

I'm getting a negative reading on the third sensor. Which one is that one?

[@focusfanatic01]

My air conditioning only comes on when in diagnostic mode.
