   simple really, the heater draws heat from the engine bay, so if the engine isn't hot then you don't get any warm air through the heaters!! you should have a temp gauge on the left hand side next to your speedo, when that starts to creep up then you should start to feel a bit more heat obviously the hotter the engine gets the hotter the air coming into the car gets! so......... if you "take it out for longer" then your car will heat up! sorted!

   check your coolant level, if it's low/empty then you either have a burst radiator or hoses, heater matrix (no hot coolant=no heat) or head gasket failure. but of course take it for a longer dive and make sure it isnt just you being silly

   lol, sean, you always beat me
   s34mer - it doesnt draw it from the engine bay. it uses the warm coolant to heat the air.

   check coolant level then, low coolant=problem as the coolant system is sealed so should never lose fluid. radiator is easy enough to diagnose, if you're not sure then get it pressure tested (2minute job), leaking heater matrix would have your interior carpet soaking.

    nope if the crack was big enough to lose pressure then coolant would piss out of it. sounds like you could have a thermostat problem- ie it isn't opening thus not letting coolant flow around the engine, that would explain the coolant level being fine yet the engine still getting hot.

    yeah so how do i check the thermostat dont i put it in a bowl of boiling water and see if it opens or some think? and if it is the thermostat thats broken take it thats what would be wrong with heater? could it also be to do with the system hasnt been flushed for over 2 years

    defo sounds like the thermostat.if ur temp guage is reading normal temp but ur heaters is blowing out cold air you need a new thermostat,dont p**s abt checking to see if its openen or not,for the price of the thermostat jus change as 99.9 % of the time this is the cause of ur problem
