Ve aerpro aircon not working

[2slow]

Hey guys I’ve got a VE series 1 sports wagon
I’ve just recently installed an aerpro facier kit and an aftermarket head unit

All was working fine before but not my air on only goes to my feet and my steering wheel controls control the heat and power of the fans

I need help on how to fix
Ive tried restarting and I’ve tried turning climate control off

Any advice welcome

Have you tried resetting the Aerpro?

 

[2slow]

Yeah I have it solved some of the problems but not all

 

[losh1971]

What has been solved and what is still a problem?

 

[2slow]

It used to blow hot air just out of the footwell vent but not it blows hot and cold air out but still only out of the foot well vent

Try a recirc door calibration

This issue may not be the HVAC controls.

This can happen when HVAC actuators fail and the HVAC module can become faulty.

To diagnose it correctly, a high end scan tool will access the HVAC operations individually, bypassing HVAC controls.

How do I do that without a high end scan tool

 

[Fu Manchu]

You can’t.

The CANbus systems run the car. If you can’t interface with them, you can’t diagnose issues.
