2007 Volkswagen Passat Wolfsburg 2.0T So, I've been having this insanely loud grinding noise coming from the glove box area whenever I turn on the recirculation mode in my car or when I go in reverse. I am assuming that is is the Heater Blend Door Actuator but I am not sure. I can't find any...

When taking the dash console trim, ashtray, radio out (replaced an aftermarket radio) and put back together, the HVAC unit stopped working. The AC light illuminates when pressing the button (and can hear the compressor kicking in), but no heated seats or fan work. Is there a fuse for the HVAC...

Hi, everyone - 2009 Passat 2.0T TSI (CCTA) Briefly, the A/C suction hose was pressed into the auxiliary fan (smaller of the two) which in turn sliced a gash in the flexible section causing all of the refrigerant to leak out. This caused the auxiliary fan to continuously run even when the engine...

As the tile suggests, I have absolutely no HVAC, no cold air at all, just outside air (blower and flaps all work fine). It could be a few things I know but what I wanted to know was how do I check with the VCDS and how do I interpret the readings to diagnose anything. (there arent any fault...

I purchased a 2006 3.6 with 47,000 miles on it last November. After I had purchased it, I noticed that the recirculate wouldn't turn on. When I press the button, the light just blinks once and doesn't stay on. Now that it's summer in AZ and it's a million degrees in the car, I can't take it...

I found the cabin air filter under the glovebox and replaced it...but I can't find the fresh air filter or inlet-intake in the firewall or hood vents. Can somebody take a pic and show me? I'd like to inspect that filter and spray some disinfectant in there but for the life of me can't find...

I had the HVAC fan motor out yesterday because it started to squeak a bit, and in the process found the flap location for cabin recirculation. The cabin recirculation flap does this (see vid) when recirculate is off. It makes noise that is rather annoying when it partially opens / closes when...

Bringing this up to the top in case anyone has a helpful input. I contacted Amazon and got a second replacement blower. The previous replacement ran fine for three weeks, then wouldn't stop running, even if the control was turned off. The second replacement worked normally for one day. The...

Hello, I've posted this because my search through the threads hasn't gotten me to an answer. So... it's been about three weeks since I put in a brand new blower fan/motor to replace the previous one that died. It has been working perfectly up until last night. The fan runs continuously at...

I recently started having some HVAC issues on my Passat. I have a blower resistor that is out. Fan only works on High (4). The A/c was working until I took it in to VW for an oil change. Now it just blows hot air. Checked the Freon and it's where it should be. I also noticed when I have the heat...

I have been struggling to find troubleshooting info pertaining to this HVAC fault code: B10A915 Control, A/C Compressor Interrupt/Short to Power. Code was retrieved using a Matco Maximus 2.0 The AC blows ambient temp air only. I tried searching the forum referencing this OE code but no luck. I...

Hey everyone, I posted this in general, but meant to post it here too. So I've scanned the threads and tried to help myself, but I seem to have found just more problems. So to start, I realized my door chime, dome lights, and puddle light did not work when I opened my driver door, so after...

Hey everyone, I've scanned the threads and tried to help myself, but I seem to have found just more problems. So to start, I realized my door chime, dome lights, and puddle light did not work when I opened my driver door, so after checking the webs, I found it may be the microswitch in the door...

Hi All, Yes, I am certainly new to the forum, but I did do my homework of searching threads and reviewing to see if the answer to my question already existed (as best I could - I realize I may have missed it). I was surprised I didn't see it, or at least didn't see the overall flow of...

Hey guys, I recently got my new HVAC box in the mail and can't figure out how to attach (1) piece of it correctly and I don't want to break anything in the process. The thing I am trying to put on is this, Control motor for recirculated air operation possibility. 2001 Volkswagen (VW) #...

2001 1.8T So my car has started doing this weird thing where the temp gauge will decide it wants to work only when it wants to. At first I thought I lost the CTS again (replaced about 2 years ago) but then I started noticing a second symptom. Whenever the gauge stoped working so did the heater...

Hello all, I just picked up an 07 with the 2.0T with the manual climate control system and realized that the air conditioner is not working. I've been pouring through the forum looking for related post's and I can't seem to find one :banghead:. So the what I'm not sure on is how the system...

HVAC pulsing noise I have an '07 with auto climate control, w/85k miles. While driving this morning my HVAC system starting making a 'pulsing' sound when turned on. It sounds like a pulley squeaking as it rotates etc. The pulsing is constant when the system is on, regardless of fan speed or...

Hi everyone! I'm here in hopes of being able to tackle a very specific problem. My Passat B3 HVAC controls started to overheat due to bad contact on the copper end of the speed dial (I guess). So, I'm searching for a replacement unit, since this one now only works in the 2nd speed. Since they...
