Question about 2002 Volkswagen Passat
Thanks for responding. Frustrated at spending over an hour on the damn internet looking for a simple diagram of what each fuse covered , driving to a parts store, buying a Chiltons repair manual, changing a few fuses that didn't need changing ( ac still blew hot ) I took it back to the repair shop this am and will let them deal with it.
I think I am going to create a diagram and give it away for FREE so idiots like me can change the fuses and get on with more important things in life.

The heater in your car depends upon a flow of hot coolant going through the heater core in order to get hot air into the car. If the heater core is partially plugged, it will restrict the flow. If you have a head gasket that is putting exhaust into the cooling system, it will eventually get into the heater core. When this happens there is no coolant in the heater core to make the air warm. If the water pump vanes have corroded away the result will be very poor coolant circulation causing the heater to not blow hot air. If your car is equipped with a heater control valve that is not functioning properly, the coolant flow will be restricted. One or a combination of these factors is likely the culprit in your case.
if the car is not overheating, the thermostat is working fine.... replace or flush the heater core multiple times to try and eliminate sediment build-up.

We had the same problem. It was an expensive fix--there apparently was a problem with the onboard computer that would periodically lock out the ignition circuit. Felt just like a bad starter solenoid--but the part cost $800, plus labor, to replace. Ouch.

COLD AIR WHEN IDLING COULD BE...
1) Low on coolant - the most common reason for this heater problem. Make sure your coolant level is full.
If the level is low, it could be because the radiator cap is not sealing well or it could also be a cracked overflow container (hot coolant that bleeds out of the engine and drops to the street so you never see the puddle on your driveway).
2) An air-lock in the coolant system - it needs to be burped. Park your car facing-up the steepest hill you can find. Remove the radiator cap a (be careful - best to do when engine is cold) and rev engine to 2000 RPM for 60 seconds - hopefully the air will burp out the cap. Top it off with 50/50 antifreeze.
3) A disconnected or cracked vacuum line. I've heard about this one but never investigated.
