  1. idle fluctuates with A/C on; stable otherwise

    Volkswagen Passat B5 Discussion
    1996 A4 Quattro: AFC engine (12-valve 2.8L V6), automatic transmission (5-speed, non-tip) New plugs, wires, coilpack, and fuel pressure regulator have restored performance, eliminated CELs and stumbles. Everything had been running very well since I redid the aging ignition system, which had...

    Volkswagen Passat B7 Discussion
    I have a 14 passat tdi highline, recently in February I received a problem where the passenger side was blowing cold air while the heat was on and driver was blowing hot air. After diagnosis, it turned out to be the common heater core problems that these cars receive and it was covered under the...
  3. B5 hesitates with a/c on

    Volkswagen Passat B5 Discussion
    My passat b5 started hesitating with a/c on. Otherwise, it runs fine. Idle also drops about 50 rpm when ac is on. Even before this started the car got really weak with ac on, but at least it was consistent. Now it accelerates rough, almost wants to stall sometimes. Any thoughts? Thanks!
  4. Melted A/C switch !?

    Volkswagen Passat B5 Discussion
    My air conditioner stopped working and I thought I had narrowed it down to the A/C controls. The button was sticking when I pressed it and the AC light did not turn on. I removed the radio, trim, etc to get the HVAC controls module out. According to the wiring diagram, the AC switch is...
  5. 2003 Passat V6 Climactic A/C Fan Power

    B5 Garage
    My 2003 Passat V6 over-heats when in stalled traffic with the A/C turned ON. The secondary small fan has no power. My independent mechanic has checked the fuses and replaced the fan control relay, but still no power. What next?
  6. A/C Not Working in 2006 Passat

    Volkswagen Passat B6 Discussion
    I know the topic of AC has come up a lot and it seems that each situation is different. So, I figured I would throw a question to see if anyone may know what we are up against. I have a 2006 Passat that I bought for my daughter, but the A/C doesn’t work. The light on the button inside is on...
  7. Passat B5 and B5.5 A/C Compressor and Condenser compatibility

    Volkswagen Passat B5 Discussion
    I found some A/C kits for Passat B5.5 1.8T, but I have a 2000 Passat BY (ATW Engine I think). Does anyone know if the parts between the various 1.8T engines are compatible?
  8. Crummy In-town mileage w A/C on

    Volkswagen Passat B5 Discussion
    2000 GLS 1.8t Auto Sedan...95k original miles. Decent Freeway gas mileage (26.8 MPG @ 75-80 MPH last trip we took, iirc) but this thing is an absolute pig in town with the A/C on, and without AC it's not much better. Tire pressures 35 front, 35 rear IIRC.. I've done 38 psi on rear, no...

  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. Blower working, but no A/C or heat in v6 b5.5

    Volkswagen Passat B5 Discussion
    Hi guys, I've not too long had this car and it's had the problem since the start, it's one of a few issues (leaking rocker cover gaskets, engine mounts and more), but is the most annoying now it's coming into summer in NZ. I've researched the possible problems, but it doesn't appear to be...
  14. 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...

  17. Doing a heater core swap - should I replace A/C evap too?

    Volkswagen Passat B5 Discussion
    I'm about to start the mammoth job of pulling the dash and swapping the heater core on my 03 V6 Wagon. I found a nearly mint salvaged dash assembly to replace my current dash while I'm at it, which is cracked and ugly. Question I have is ... does it make sense to swap the a/c evaporator at...
  18. Odd a/c issue

    Volkswagen Passat B7 Discussion
    I have an odd a/c issue and was wondering if others are seeing the same issue? 2016 1.8 TSI SE. After the car sits over night, the next day the a/c blows ambient temp for 5 minutes or more before blowing cold. The compressor clutch has kicked in during that time period. After it starts...

    Volkswagen Passat B7 Discussion
    Hi all ! I keep my car in the garage at night so when I leave for work in the AM, the interior is not super-heated. I turn on the A/C but it blows basically "room temp" air for the first couple miles. Then, it starts blowing cold (38 degrees) air and works as normal for the rest of my...
