Heater also utilises the hot water provided by the engine cooling system.
This radiator pressure release valve may be affecting the heating initially until it valve opens up.All the hot water is channeled into the head and block to warm up the engine and the valve is closed at this time.As the temperature comes up it opens and lets more water through, that heats up and this open system supplies the heating unit?
Throw the pressure release valve 'cold' into some hot water and see if it opens up?Check to see if it works ok?

Thanx to my friend DOPE for support , but I will try to explain the problem with my City T1 - THE WAY THAT I CAN - so when I turn on the car... from all vents blow cold air ( the engine is cold...normal ) after few minutes I turn on the heater ( non the A/C ) - my car have STOCK AIR CONDITION ( with freon ) and HEATER ( with fan ) - I use only HEATER ( in red diapason of temperature scale - around 28-29 C ) because I haven`t freon now...so when i turn on the fan of heater in position I II or III ( I II or III - position of power of fan ) - the HEATER work with normal noise and power. I have 4 positions of mechanical switch of HEATER:
01 - front vents ( 4 circle vents ( 1 left , 2 central and 1 right vents )
02 - front and foot vents
03 - foot vents ( 1 down left vent, 1 down right vent )
04 - windscreen dash vents
the PROBLEM is : when I switch these 4 position I see
on position 01 - blow only COLD AIR from 4 circle vents
on position 02 - blow COLD AIR from front vents and HOT AIR from foot vents
on position 03 - blow only HOT AIR from foot vents
on position 04 - blow only HOT AIR form windscreen dash
Is this normal for HONDA CITY TURBO 1 1984 ????
Oh, I forgot to say that my car have STOCK FRIDGE for cold beer.he is direct connected between left front vent and central front vent...
WHO HAVE T1 1984 Year with STOCK A/C ( with freon ) and STOCK FRIDGE for cold beer?
Thanx again....
