Heater always hot, even when it's on cold?
Mk4.5 smiley face
You get the engine up to operating temps and then all you get is hot air through the vents, even when the dial is turned to cold
It psychically stops when it turns at either end so I'm not sure if the cable has come off or not, but sometimes it totally cold before getting blisteringly hot again
It's got ac if that makes a difference
Any pointers?
