Heater direction problems

[COMMYBOI]

Hi just got a vn 5L 5spd
The heater direction won't work. I have checked and found that the hose at the back of the motor was unplugged so I plugged that in to the vacuum line off the throttle body and still nothing. Please help i can barely see out windscreen

Check that the one way valve on that hose you reconnected is the right way round. Then it's just fault finding where the vacume stops working. Check if your vacume ball has vacume after you stop the car to check the valve.
