Hot Air coming outside passenger side air vent
 

Hey peeps

Noticed an issue in my 2013 BRZ now that weather is warming up in Australia and I have to start using A/C!

The passenger side air vent is putting out hot air despite the dual climate control being off and the temperature dial set to low with A/C on. I have cold air coming on the drivers side vents and I am able to switch that between hot and cold air.There's also a clicking noise coming from the dash when I attempt to change the air temperature controls.

What's the issue here? Is this an easy fix?

I had it the other way round. Passenger side (RHD car) was blowing colder. Was due to a leaking cooling coil.

Enable the dual zone control and try to change the passenger side temp, if that reproduces the clicking, you've most likely got a failed blend door actuator.

Okay, this seems to be it. Have no idea where it's located in the car though.

This may help*
