So I have just had a regas on my el.  My issue is when it’s on fan speed 1 or 2 on face only it is feeling cool but not a lot of air flow. As soon as I select 3 or boost it starts blowing warm air. This is still on face only.  When I turn it to face and foot it is blowing cooler but warm air come to the feet which I think is supposed to be normal given there is a blue arrow for face and red arrow for feet.  On demist, demist and foot and feet only it’s blowing warm air.  What could be the issues.  It’s been so hot I don’t want to drive it.
