    I have a very similar problem.. I already spent over $400 trying to fix it and barely any change. The mecanic changed the thermostat, and did a flush. He is now saying that is maybe the water pump!! (Wich BTW I changed less than a year ago). Right now it blows some warm air while I drive my car very fast, but is not so warm if my car is stop at a traffic light.

Do you notice that the engine coolant temperature gauge stays on the lower part of the scale as well? If so, it's likely that your thermostat is stuck open - this prevents the coolant from staying in the block long enough to absorb heat that is used to heat the climate-controlled air. I'm not positive on the 3.0 in your car, but the 2.8 V6 in my Audi A4 requires tremendous disassembly in order to change the thermostat. I believe the 3.0 is the same - the labor involved is only slightly less than that required to do a timing belt change (which, if you change the thermostat, since you're already all the way in there, you may as well do the t-belt service as well so you don't have to pay for all that labor again any sooner than necessary).

The heat in my Volkswagen passat 2002 only gets warm while driving. when sitting it blows out cold air. what is wrong with my heat


Sounds like either low anti freeze, thermostat is not working or your heater core is leaking. Is there any anti freeze leaking under the car? You water pump could be bad if there is fluid on the ground below.

2008 land rover sc warm up car turn on heat blower working warm air at first then clod no heat


When is the last time you change the thermostat and coolant?
Recommended interval is 2 years.

Coolant is the heat carrier to heater core.
Top off the coolant level for now and re-test.

2004 vw passat w8 won't blow warm air until car is moving


Could try to change temperature sensor (due to MIL light), but it doesn't cause no heat in vehicle. Most likely caused by air-lock in heater hoses at heater core. Try bleeding hoses to eliminate air.

The heat for my 2002 passat v6 does not work proerly, it blows out cold air when sitting still and warmish air when moving.


sounds like the raditor is not full.
fill it and let it run with cap off after it get warm look and see if it went down and add more water or antifreeze to get it full.
other wise it could be clogged and you will need to back flush it.

2004 passat heater isn't blowing hot air. both hoses are hot going into the heater core. anyone had this same problem and how can i fix it?


we have a 2004 passat with the same problem. after many different attempts. what we did was. drain the heater core, blow air through the system and then put a mild solvent in the system and let it set for about 20 minutes. flush the system and refill with coolant. now our heater burns us out. use low air pressure and be very carefull. heater core was full of junk that came out after we flushed with solvent.

Runs hot and hearter not blowing hot air


a heater uses the temperature of the cars water, running threw a heat exchanger if the heater core has failed water will not circulate threw the engine properly this will and can cause over heating as well as nothing blowing from the heater. good luck.heater cores are generally inexpensive parts to replace.

last thing you can check if heater core is ok. is the thermostat.

I have a problem with the heat in my 99 4 runner. It takes a long time to heat up and reach normal operating temps, and even longer for the heater to start blowing out warm air. The worst problem is if the...


When was last flush and thermostat replaced? Also, it may sound crazy but, when I have a partially clogged heater core, which I suspect you do, I usually will disconnect the hose at the heater core, and connect a drill operated pump from hardware store (about $10) to the heater core, and circulate C.L.R through it before putting it all back together. I usually set it up to pump through the core and back into a pail or similar, and then reverse the hoses to allow flow opposite way as well, then I plug lower inlet to core, and fill with C.L.R, and let it sit overnight if I have time, just to clean out as much calcium clogged up in there as I can. Saved me replacing 2 or 3 heater cores so far, that had little or no heat at idle, prior to cleaning, but had good heat after.

if the engine is full of stop leak it would over heat not no heat. check the thermostat & make sure it's not stuck open with stop leak. then make sure you bleed all the air from the system.

Good luck.
