    I have a 2002 Passat B5.5 V6 and recently I've been having problems with the A/C - the temperature displayed is at first correct and then will start dropping to anywhere from -49 °F to 11 °F. It's now been constantly in that range for the past few days and never displays the correct value. I...

    Hello I have to re-fill gas in the AC unit every 6 months or so due to leaking. I understand it's a known problem with Passat B5s. On the last time I was at the shop, the guy said he could seal it somehow with some material* so that the leaks would stop. Is that recommended? or should I just...

    The 4 position cabin fan switch does not work in in the first two positions. Neither the fan or AC is actuated. When you advance the switch to the 3rd and 4th position, the fan and the AC function normally. Any idea of what this is and how to fix it? I don't see how it could be a fuse issue...

    I'm not sure how to explain this so moderators feel free to step in here and clean this up if necessary. My AC wasn't working on two of my vehicles, one a Passat and one a Civic. I recently bought one of those freon-in-a-can rechargers and recharged the systems. You can read the Passat part of...

    Now that it's 90 degrees out on a daily basis, I've been using my AC. The only problem is it causes the car to stall. At first it was just in parking lots with the steering wheel on full lock, making me think that was too much demand from the engine so it stalled. But it then stalled when I was...

Sometimes when I run the Climatronic AC while driving around town, if I'm driving slow or kind of stop-and-go traffic...the AC will start blowing out warm air.
