Hi, similar problem. Seemingly there is a fix that works for some...

Turn climate to low.... with engine running, and up to temp I assume... then slowly turn temp dial up to max, then slowly turn back down to low... maybe repeat a few times?

I’m gonna try next time I take the car out...

I was about to post the same fault but, starting at "low" and turning the temp up very slowly to "high", then slowly back down again just worked for me

I posted this issue earlier today and another member suggested this (thank you ‘Welton’)... so can’t take the credit...

At least it’s a cheap and quick fix?
