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.

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.
