  1. B5: Climatronic: how to fix or replace evaporator sensor?

    Volkswagen Passat B5 Discussion
    I have problems with Climatronic HVAC (A/C) system in B5 Passat. I was able to diagnose the problem using the Climatronic interface and channel 40 ("Evaporator Temperature - Actual value") says that the evaporator temperature is -51 °C (-60 °F) which is obviously not the correct reading. (Press...

  3. Climatronic not blowing cold on left side of car

    Volkswagen Passat B6 Discussion
    Hi all, am o correct in thinking this is likely a flap motor fault? 2006 3c. If I crank the heat it blows hot on both, but turning down to low gets kind of room temp from the left, icy cold from the right
  4. No defrost on Climatronic

    Volkswagen Passat B5 Discussion
    Hello everyone. I have a problem with my CLIMATRONIC unit and I think it has started since retrofitting MFSW but that shouldn't have anything to do with it (other than maybe I damaged wiring?). Everything works, I can have cold air I can have heat, but no flow to the floor vents or defrost, just...
  5. 2002 V6 climatronic no heat

    Volkswagen Passat B5 Discussion
    The dashboard temp gauge shows the engine heating to normal temp and staying at normal temp. When I turn the heat on it blows cold air. My question is: Do the codes mean that is actually the problem? Or, is it possible to have those codes but the flaps are actually working properly? I...

  7. Is there a trick to removing Climatronic head unit ?

    Volkswagen Passat B5 Discussion
    I removed the trim piece and the 4 t-20 screws, but the unit will not come out. The bottom of the unit is loose, but the top is caught on something. Any hidden screws that I missed ? Thanks.
  8. Passat B5 Climatronic Code 4B6

    B5 Garage
    So my wifes 2000 atq wagon has been having issues with the blower motor cutting out when it was on. So i found out how to do the self diag on the climate control panel and got code 4F9 which was a fault in the blower motor. So i change the blower motor and resistor and went to clear the codes...

    Volkswagen Passat B6 Discussion
    When I turn the climatronic fan on it turns on, the lights are on but no air blowing. Any ideas? It's 07 2.0T B6.
  10. Need a suggestion on where to go for Climatronic repairs

    Volkswagen Passat B5 Discussion
    She just turned over 200k miles and still a pleasure to drive. I tried to diagnose the issue where the heater is stuck on and got codes, but beyond my ability to fix. I live in Bradford county PA, and don't know where to go to get it fixed. Live 15 miles south of Towanda and have no dealerships...
  11. Climatronic Theory of Operation?

    B5 Garage
    All: Is it normal for the A/C compressor to run all the time? We have had ongoing heat problems and I realized, this evening, that the A/C compressor is running all the time, so the A/C is competing with the heat and, when it's cold out, winning. We've been seeing single digit temps recently...
  12. A/C problem in climatronic v6 - Lots of T/S already!

    Volkswagen Passat B5 Discussion
    Hi all, I'm getting no cold A/C at all and have troubleshooted the following: - Only a recirc flap sensor issue on climatronic, shouldn't effect A/C? - Gas is at good pressure - 267 Relay seems good (disconnected it and A/C clutch doesn't engage, reconnect and clutch runs) - Red valve thing...
  13. A/C or climatronic issue

    New Member Introductions
    So, I bought my 2003 2.8 4mo wagon a week ago, and my A/C doesn't work. It's fully charged and doesn't appear to be leaking. I figured the compressor/clutch may be out, but when I switch to ECON mode it still blows hot, yet it's 32 degrees outside. I was under the impression ECON just disables...
  14. climatronic servo

    Volkswagen Passat B5 Discussion
    so, the servo for the blend door crapped out. It was stuck on AC but that's been remedied.:lol: what I am wondering, the part number on the OG servo is 8D1 820 511 B. Rock auto has 511 G and my buddy at the dealer says I need 511F. Is there a difference in any of these? They all look the same.
  15. Climatronic problems-heat stuck on

    Volkswagen Passat B5 Discussion
    During a 12hr road trip yesterday the Passat decided that rather than supplying a/c thru the dash vents, that heat would be a better idea. Wouldn't be bad, but it was 85+ degrees outside to begin with. With the system shut off it still made the closed dash vents almost too hot to touch. It...
  16. 2004 B5.5 Climatronic oddness

    B5 Garage
    Hello - noticed an odd behavior, and a read through on all the threads didn't prove terribly helpful, so here's whats happening, and if anyone has run into similar I'd love to hear what you did about it. AC works and blows cold, but every once in a while, I will hear a "whoosh" and the AC...
  17. Climatronic defrost and footwell vents swtiched after replacing servomotor

    Volkswagen Passat B5 Discussion
    :( I wonder if anyone ever been there. A couple of months ago I noticed that I was only getting air from the left side of the center dash vent, the passenger side was completely dead. A quick scan on VCDS showed me the following: 00603 - Footwell/defroster Flap Positioning Motor (V85)...
  18. Climatronic unit swap

    Volkswagen Passat B7 Discussion
    Hi, My Passat is an early B7 (European) with the 2nd generation climatronic control unit and I would like to upgrade this to the 3rd generation unit. My impression is that this is a direct swap? I have used ETKA to narrow down the list of possible revisions I may have to: 5K0 907 044 GM or 5K0...

  20. Climatronic controller replacement question

    B5 Garage
    All: Looking to source a used controller to replace the one in my 2002 Passat GLX Wagon. The current unit is P/N 3B1 907 044 J. My question: Does the "J" suffix matter? Lots of P/N 3B1 907 044 with other suffixes on ebay. Thanks.
