Assuming you have a non-AC car. Though the layout may be different on your RH drive car, your heater box should work the same way. Make sure the 3 cables are connected to the box and operating the internal doors/flaps correctly.

Also, even if the flaps are opening and closing, the foam on the metal flaps may be rotted allowing air to leak past them.
