Hi
I have a heater that is blowing out cold air on my S30 even though the lever points to hot and the engine is hot. To be honest, it has never worked since I bought the car last May but I never really worried about it in the summer.
I have tried flushing the heater matrix but disconnecting the 2 pipes leading to it that pass through the bulkhead and water passes through both ways. the hoses get hot under the dashboard and there seems to be heat both sides of the hot water valve so I don't think that is blocked but I cant get any hot water to run through the matrix with the engine running and no hot air. The thermostat is fine (just replaced it).
Am I missing something? Could it be a dodgy water pump and is there any way I can test it without removing it first? Any suggestions would be greatly appreciated.
Thanks
Paul
