Audi A4 B6 B7 Blowing HOT or COLD air FIXXX

[@djhatstand7312]

Those actuator motors also function as potentiometers, so the HVAC unit knows exactly what the position of the flaps is, usually the tracks get dirty, you can take them apart and clean the crap off the tracks and regressed them, usually when they go funny you’ll hear the motors keep operating when you park up as it is trying to recognise what position the flap is at

[@ali264504]

Very well demonstrated 👍

[@CraigMansfield]

Yes, I've heard that. 👍👍

[@PasTimez]

Just completed this fix. I advise doing some yoga before you attempt replacing the motor under the steering column. This was an absolute nightmare.

[@andyhopperart470]

Yes !!! Working upside down, with your body contorted over the shape of the car and lying into the footwell is a bizarre piece of self-inflicted torture !!! 🤣🤣

[@jonassrensen2629]

great video, helped me diagnose my audi a4 b6 that was constantly blowing hot air on the right side. Straight to the point no bs good job :)

[@livy4life]

The motor with the purple arm is for the temperature and NOT the flaps. I opened up mine a couple of weeks ago, the passenger side stayed cold. I soaked the potentiometer in contact spray for a little while, it's running fine now. Now I have to refurbish the fresh air intake motor, that one is stuck right now. No air flow in the cabin, on circulation I got full blast. So the blowermotor is indeed still working.

Brilliant video ,u make it look easy

[@iwinandrew2841]

HI, Thanks for the video. It was educative in general. In my case the motor is blowing but the heat is mild even on high. Hence I believe the vent is jammed. Please advise.

[@Justinlifts365]

[@Kokokasakero]

Did you fix it ?

[@zappa264]

@@Kokokasakero no but in my case it appears to be a thermostat problem. The heating starts working when I drive the car

[@michaelmcglinchey4347]

Thanks for an extremely helpful and informative video. I'm having cold air on the drivers side and nothing blowing on the windshield so have to assume that the flaps are stuck - hoping your proposal will solve both issues.

[@connormckeon8101]

Did it solve this problem? I’m having the same one

[@skogskiwi3335]

Hey. Nice video. Question: mine almost doesnt blow air at all, no matter How Much you turn it up. However, if you switch on circulation, it blows normally. And i know this will sound wierd, but it also blows normally for about 5 seconds if u turn on wiper fluid lmao. What could be faulty?

[@Zorzgospodo]

Same thing 😐

[@danielmckay7262]

Mine does the same as well.

[@linceboard]

Exactly like mine

[@onememories8523]

Thank you so much for your video ! Great information!!! Question. My ac system is fully charged but I won't stay on. It would stay on for like 1min and then switches to cool air. Is this a possible faulty "blue" flapper motor ? Please let me know what you think. Thanks

[@ozzystravels]

Thanks mate mine is the overhead looks easy enough to fix

[@ali264504]

Very well demonstrated 👍

[@vanstreun]

What servo do I need to change if both sides keep blowing cold air when set to the hottest setting?

[@andrewgiron348]

Same here blowing cold no hear

[@andrewgiron348]

Heat

[@vanstreun]

My head gasket blew a day after this comment, was probably already leaking. Heater core filled with air.

[@trist03pm]

@@vanstreun That's terrifying...lol My heater only blows cold air too.

[@Shakester71]

What if both sides are blowing warm air while on the coldest setting?

[@jesperp9081]

Did you find it out?

[@Shakester71]

Jesper P Yes. There was a small crack in my lower high pressure pipe so i didn’t have any freon. The skid plate that cover the bottom of my car kept on dragging so I took it off exposing the pipe. I’ve must have bottomed out and cracked it. If your ECON mode light remains on, then you might be leaking or out of Freon.

[@michaeldobson8859]

Mine blows cold at startup but slowly over time transitions to blowing fog then to just barely cool out of all the dash vents. I believe it is a damper controller or the head unit itself. Which damper motor would affect both sides by adding more and more heat to both sides evenly.

[@TyroneMaye]

@@michaeldobson8859 what is head unit ? and would that be same for the 07 Audi Q7 HVAC system ?

[@maradonna911]

What are the acutally part description and part# for those motors?

[@TyroneMaye]

Ok this what i am getting with my 2007 Q7. The climate control with both set to........ HI....i do not feel any heat coming through any of the vents. So when i turn both drive and passenger dials down to say i set them both at 75 --- 65 right, then the heaters begin blowing from each of the vents. Is that normal or is there a problem with my heating system ? This is my first Audi Q7 so i am learning as i go here with things.... Thank you for any advice or tips you may be able to provide in relation to that if you have ever experienced this what i described here. again thank you.

[@jgoeke1]

awesome video. the most helpful of all the ones i've seen. you actually identify what each servo does. So helpful!

[@gk_studios]

What servo controls just the middle vents? My AC blows cold out of passenger and driver but warm out of center vents…TIA

[@kirkswenson7566]

Will most car mechanics know how to diagnose and make this repair or would this be for some sort of specialty shop to handle? Do I dare ask if a Aidi service shop would be a viable and cost-effective option?

[@kymarnitamati278]

Same issue here mate, but opposite my passenger hot/warm and my driver side only blows cold would I need the same part as yours ? If so

[@cTTbLaKeMAn]

mine does this too.... driver side facing vent blows as cold as it will get and the middle vents and passenger vents only blow luke warm, barely cold air... good airflow though on all vents..

[@alexsexoticpets746]

I have a 2008 Audi A4. Not blowing any cold air at all anymore. I started hearing a tap noise at first and then suddenly it stopped blow cold air. Which actuator would need replacement??

[@rv3089]

I have this issue where my A/C works if i’m running the car (sometimes). if the car is parked, forget it! the a/c won’t work. Other strange fixes; it works fine after getting a carwash or if it’s cloudy. it sounds super strange but i beg you to believe me.

[@floridiankicks4543]

Roberto Vera I have the same issue when I’m driving it’ll be Ice cold, but when I’m at a stop sign or red light it’ll get warm at idle, not sure what the issue is, my check engine light is on because of a fan that’s not working

[@vusiwekhumalo6715]

Your condenser fan is not starting up. that's why you only get cooling when driving in cold conditions and for the car wash you condenser is obvious full of water which cools it when driving.

I just bought an Audi B7. When I turn it on or press the recirculation button I get a low clicking noise from the flap motor. I took out the glove box and I see that the flap opens and closes properly but I hear a low clicking after it is fully closed or open for about 5 seconds. Is this normal?
