Hmmmmm im sure ma bros VTR had this. Im pretty sure that its something to do with something behind the dash. If the hot water doesn't reach this (a small radiator i believe) then there will be no hot air in the car.
If you flush out the radiator, it may remove the blockage allowing the hot water to flow freely to the mini radiator. If this doesn't work then i think you would have to buy a new thing behind the dash.
Hope this helps

Make sure thers no leaks from radiator what a would try is buy some radnol the dear one at about a tenner then first of all fill up with some water till its bled its a little screw wen water comes out put it back on now pour the full bottle in radiator let it tic over for ten then put more water in if needed.. worth a go

its an airlock in your system, probably the heater matrix bit. Either that or low coolant level. Do you get the sound of water coming through your dashboard? Check the pressure on the radiador pipes. If the pressure is high (cant squeeze the pipe easily) it could mean a head problem. Let us know how you get on

Mate had this issue with her KA Sport. Turned out she had no coolant. Topped it up and heat was restored!

I'll check the coolant level etc.

Only bought it yesterday you see, so sorting the niggly faults.

Cheers guys
