Hi! I'm hoping someone here can help me.
I've got a 2013 Aurion and a few months ago the heater control unit stopped responding. The light goes on, but none of the controls work except the hazard lights button. All fuses/relays are in good order.
I bought a 2nd hand replacement heater control unit and fitted it and it worked for a few weeks but now it's doing the same thing again :( I have exactly the same problem! Has anyone faced this or do you know how to fix it?
I made a short video of the issue: https://youtu.be/PWW17AuocuM
Thanks in advance.
