Chances are your heater core is no good. This can be near a thousand dollars in labor alone with another $100 or so for the heater core itself.

Why is the driver's side rear floor flooding with water even with no rain in your 2003 VW Passat?
You have a leaking Volkswagen heater core. Working much like a small engine radiator, the Volkswagen heater core provides heat to the passenger compartment on cold days by circulating warm engine coolant through its tubes. You're simply using the Volkswagen heater core to extract heat that was going to be radiated to the outside air anyway. The construction of the Volkswagen heater core means that it's going to go bad someday, since copper and aluminum don't last forever. To make matters worse, the Volkswagen heater core is located inside your car. That means you have a potential source of hot water sitting just inches from your legs. The might be pinhole leaks, cracks in the tubing, and other minor maladies. You'll have to replace the Volkswagen heater core if you don't want your floorpans to rust out.

Why does your heater blows cold then hot then cold then hot?
It is because your heater is having to heat up so its blowing cold air out while its heating up.This means your heater is not very efficient and it needs to be checked.
Why is your 93 GA GT runs cold and the heater does not work?
If you are saying the heater is blowing out cold air you need to change the heater core which is located inside the dash
I replaced the thermostat in my daughters 2000 passat and took it and had a coolant flush done and it still throws cold air. The mechanic told me the problem is coming from under the dash?
check the heater core to see if it is clogged make sure it flows well - volkswagons are common for having air when replacing cooling parts- volkswagons have special bleed procedure to bleed air out of cooling system- make sure water is flowing in and out of the heater core properly- the thermostat will not open to allow water to flow if there is air in the cooling system and then in tern will not flow through the heater core to allow you to feel warm air flow into the cabin
Why does cold air come from the heater?
possible clogged or damaged heater core
After flushing coolant and replacing thermostat heater now throws out cold air on a 2000 Toyota celica?
Flushing sometimes frees up mineral deposits that then clog up your heater core. My mechanic told me to never flush a Toyota as the heater core was low in the engine. That is, only drain and fill when doing a coolant change to prevent dislodging the deposits.
Car heater blows cold air when not driving?
A car heater taps off engine heat. If you aren't driving, then the engine is cold and there's no heat for the car heater to use.

Get the air out of your heater core.
