    i have the same problem, the heater is blowing out air, but no hot/warm air. How can i fix this and are there any diagrams i can look at?

    I had the same problem and it could just be an air lock and pump cannot pump air... the hose that go through your firewall rise quite high and can get air in there if you have had any work done on the heating system. The solution is to slide one of the hoses back at the joint as it has a small hole in it to allow the air to escape and while the car is running wait till the fluid comes out of the hole and then slide the hose back on... Good Luck

You will have to change the heater core. 9 out of 10 times, when the heater is not heating the air, it is a bad heater core.

You probably have a leak in your oil cooler. This is causing the oil to bleed into your cooling system causing the "thick brown liquid". This in turn will also cause your engine to over-heat since the cooling system is contaminated.

We have an audi a4 2.6cc , the heater only blows cold air we have had a new heater matrix a new water pump and thermostat and a new radiator now it blow luke warm air but not hot,please any ideas


sounds like the thermostat is not functioning correctly? either that or not in at all? thus making the water which would normally warm up quickly, warm up extremely slowly and on really cold days not at all? with a 2.6 engine your car shoudl warm up in record time?
