  1. AC and Heater not working, what to do to fix it?

    Volkswagen Passat B6 Discussion
    Hi folks, A couple of weeks ago my dad's B6 TDI passat's AC stopped working. It only blew warm air. The weird thing is, after I checked it, the heater also doesn't seem to be working. It does blow air, quite well actually, which means the fan is still working, and the fuses are good, so those...
  2. W8 Heater being naughty....and then not.... and then again

    B5 Garage
    Hey so my W8 has a heater problem. Ive gone through all the troubleshooting and infact plugged in an ODB. But the problem is one of those cool ones that is intermittent. Heater will operate for perhaps half an hour - quite well. And then it will just stop and begin blowing cold air. And I was...
  3. Looking for heater core firewall nipple repair posts

    B5 Garage
    Good morning! Sorry for this post, but despite searching on a variety of terms and looking in the Information Base, I cannot find the handful of posts on this topic (except for the one using the Prestone flush kit--I found that one). In particular, I'm looking for one where someone added copper...
  4. Heater core pipe leaking!!!!

    Volkswagen Passat B5 Discussion
    So I have the dreaded heater core plastic pipe leaking :( It's leaking from the pipe that doesn't have the bleeder on the hose (The inlet pipe)? It looks to be 2 pin holes between the rubber boot and the hose. I know the fix is to replace the HC but I don't have time to do that now. There was...

  6. Replacing the Heater Core

    B5 Garage
    :wrench::wrench::wrench: Winter has come, and my heater core has decided that it's time to go out on me. I've never tried to tackle this job by myself, and since it's close to Christmas, I'd prefer not to spend the money with a shop. I know the method most of the repair manuals provides, which...

  8. 2010 Passat block heater

    Volkswagen Passat B6 Discussion
    OK...I'd like to think I'm no dummy, but I can't find the cord. Living in Canada it's absurd to think it wouldn't have a block heater....It's a Canadian car too. 2010 Passat Wagon highline 2.0l. I've google the crap out out of the subject and it looks like they didn't have any...TO ME THIS IS...
  9. Cracked heater inlet

    Volkswagen Passat B5 Discussion
    The inlet of my heater core (2000 B5 GLS V6, automatic) is cracked and has steam and coolant shooting out of it when the car gets up to temperature. Is there a fix that any one that works on this plastic - I can tell you it's not JB Weld! Yes, I could bypass the core altogether until the...
  10. B5 B5.5 Passat Coolant \ Heater Hoses Life Expectancy

    Volkswagen Passat B5 Discussion
    Question? What kind of life are you all getting from your coolant/heater hoses? My 2005 TDI BHW engine code has over 200,000 miles and all the hoses (except elbow hose for the rear flange, it's 5 years old and 70,000 miles), are original. They all appear to physically look good. Given the...
  11. stinky heater

    Volkswagen Passat CC Discussion
    Hello all. I was reading an article about some Passats having a musty smell when you turn on the heater. The car I just purchased has this problem. Any help you can give on the fix would be very much appreciated. Thanks.
  12. Have you Changed the Heater Core the "Fast" Way?

    B5 Garage
    Have a 2003 1.8t with an AT. Wanting to change the heater core by pulling the dash out as a complete unit (the fast way). I have done this before and it worked great. But this time I am stuck. I have done everything on the youtube video except removing the nut from the wiper mechanism (I...
  13. Heater Core placement question

    Volkswagen Passat B5 Discussion
    Is there no other place the HC can go?? Maybe moving the Battery to the trunk and putting it where the battery was? Is there any reason why it has to go back where it currently sits? Just curious as it is a decent sized project when replacement is called on. Thanks
  14. 2013 Passat S 2.5l - Heater wont turn OFF

    New Member Introductions
    I just recently ran into the problem where I turn ON the heater and it heats up but then you cannot turn the heat off. The temperature knob has not effect, it stays hot. The fan control works fine, the A/C works fine. I have to either turn the fan all the way OFF or turn the system OFF. If I...
  15. Heater core inlet/outlet woes.

    Volkswagen Passat B5 Discussion
    Hey folks, so after doing a whole lot of work (timing belt, oil seals, alternator regulator, cabin filter leak) this summer/fall on the Passat going to my son's mother, I've run into another issue that I'm hopeful I can resolve with some of the info I've gathered on the site. After a couple of...
  16. Is it the heater core?

    Volkswagen Passat B5 Discussion
    Hi all, 2003, 1.8t Today I discovered that the driver floorwell, the center area, is wet but not soaking wet. When I scraped the carpet with my shoe heel, very little water accumulated. The car sat in the garage for the last 4 weeks so I don’t think it’s the sunroof or else. I touched the...
  17. Heater!

    B5 Garage
    Hi all. Ok the latest thing on my passat is that the heater doesn’t blow air. Even on high, you can hear it as if it should be blowing tons of air out, but it just sort of dribbles out of the vents. Car is warm, the tiny amount of air coming out seems warm, and again, it sounds like it’s...
  18. B5.5 Heater core question

    B5 Garage
    Hey guys, this has never happened to me but I was just driving and my car started overheating. As I was pulling it over, it sounded like my heater core popped and coolant steam entered my cab. I will say that I had just recently changed the thermostat housing and thermostat. I had just purged...
  19. Heater Core Flush Success!

    Volkswagen Passat B5 Discussion
    Just completed the heater core reverse flush of my wife's B5.5 2004 Passat. :D I think it took longer to put the jig together than it did to flush out the core. The heater is now blowing HOT!!!! Thank you for passatworld.com. There was some sediment and it took about 5 five gallon buckets...
  20. Heater core hose

    B5 Garage
    So I drive an 01 Passat 4motion V6 wagon. Last weekend, I started dumping coolant everywhere. Upon further inspection, I found the heater core inlet hose broken off (not from the heater core but from the other end way down behind the block) I got it all apart and everything. What I really need...
