    start with a volt meter unplug the pigtail wiring to the blower motor and add two paper clips or you can just back probe the wires its above the passenger side kick panel with your volt meter check to see how many amps its pulling if its more then the fuse rating that is called for then you need to replace the blower motor

    amperes must be measured with the test equipment in series with the circuit or with an inductive amp probe

Try removing he heater hoses going into the firewall(when cooled)and blow the heater core out with compressed air.Or you could have the cooling system flushed.

SOURCE: 2004 VW passat not heating

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.

There is an electrical relay that is malfuctioning. I had the same problem on my 2000 VW Passat. I just got it fixed, part cost 48 dollars and labor will be about an hour.

1999 VW Passat AC/heat doesn't work? The belt broke this summer? I was told should still blow heat even if no belt?


If you are talking about the belt for the ac compressor, yes the heater should still work.
If the blower is not working, you will need to have the blower motor checked for voltage and ground.

Air and heat not blowing air through vents


Either Your fan switch is burned out or you blower motor is no good, your blower motor is on the passenger side under the dash. Before you replace any parts you need to check your fuses and relays under your hood and in the car. Usually if your fan switch goes bad you will still get some air blowing thru the vents, so my guess would be blower motor, If its not a blown fuse or relay.
