after my heating being warmish i drained refilled step by step from guide on here, still no hot air,everything is all ok but no hot air, do you think heater controls are faulty? ive done this 3 times with no joy (drained) temp ok,no leaks, no hg signs,idling perfect , radiator hot everywhere, doing my nut in now! oh and thermostat fine( how far does it open,mine was 5-10mm).

 

does it get hotter if you drive it??

 

i get some warmish air but not hot,hot.also should the engine check light come on when turning over? mine dosnt

 

No to the checklight.

Does the interior fan work? if not, check fuses.
If all else fails, you MAY find the linkage that moves the flap to divert air over/through the heater matrix, is either dislodged, or broken.

 

Are the hoses to the heater matrix getting hot?

If so then water is flowing through, check both in and out.

So if they are hot, its an issue with flaps etc thst divert the air around the dash to either the vents or windscreen.

 

But do check the heater fan: when my interior fan went of the Xantia, the car would only give WARM air.

 

This could be a faulty heater matrix or a duff water pump.

 

when i checked my thermostat it only opened between 2-5mm, 5mm max,i looked on you tube at another one opening and it opened alot further is mine working right ?

 

sorted!!!!! the return pipe from matrix was blocked as it goes through small hole on crossover pipe, all sorted thanks chaps.

 

There we go lol.

Glad its sorted!

 

was like winning the world cup, checked all controls and they were moving as they should,felt the pipes from matrix and one was hot and other felt like it was getting warm, squeezed return pipe a few times at point it meets crossover then all of a sudden heat! spent three days draining,re-drain ing, every time doing it as said on here, amazing what one little gap can do. learnt loads through the experience though.

 

You might think of draining again: you've obviously dislodged some debris, you don't want it blocking something important.

Maybe do a flush too.

 

was thinkng that, though dunno if my back can take the slow back filling again lol.

 

It does take it out of the old lower back.
