Heater works, blower works, but doesn't blow hot air

Hi there, on a mk2 my blower blows away on all settings and my heater works but with the blower set to high I get no difference in amount of air pushed out the vents. I am thinking perhaps some hose disconnect but wondering if anyone got any ideas?

Thanks

Andrew

Probably disconnected under dash passenger side. Does on mine all the time.

If you remove the glovebox (simply open & push in the sides, and pull), you will probably see the problem

Excellent, thanks for the pointer and yes obvious when you remove glovebox I can see the hose come loose from the heater - thanks all fixed now.
