Cabin heater fan motor not working

You could try but I don't think it will work.

From the picture attached, you can see the reverse of the fan, the bits that need to be lubricated are behind the fan blades.
 
A cold, dark, damp night! (no, not the start to a best selling novel!, LOL!). I got into my A2 and BOY, did I need heating/air, etc!. Nothing from the fan, not a whimper!. So, out with my hanky (very soggy after that!) and I drove home with the windows partly open. Not very pleasant! SO, next day, there I was looking at the A2OC for help, and I came to this very thread! It proved helpful ..... (that is just what this club is all about!), so I too now want to add to this thread, giving my experiences. Well, reading through the thread, questions seem to have been asked and not really answered .... SO, from first-hand experience, this is what is do-able! O.K., the fan has stopped working .... first, check the 30amp fuse, position 16 ... if it's O.K.,then remove the glovebox section (one screw is hidden behind the coin-holder rack) Switch on the ignition and select "recirculate" on A/C unit. Switch off the ignition again. The two flaps below the fan housing will have opened. Reach inside and test if the impeller rotates freely. (There will be some slight resistance, but it should turn fairly easily) If it is stiff, then the fan is the trouble and will need lubricating or replacement. You can check this by applying an independant 12V supply to it, although it has been shown in this thread that it may still operate in this mode, but not when re-connected!. I had the luxury of a complete spare blower ... it was easy to just connect the spare and prove conclusively that the existing blower was the problem! Now we move on to blower removal .... there is no need to remove the dash and there is also no need to remove the airbag! An absolute requirement is a flexi-drive screwdriver ... I used a "Stanley" 62-508 flexible screwdriver. The blower housing is retained by 5 Torx T15 screws. Before removal, there are small sets of wires to be freed by cutting two tie-wraps holding them to the blower housing. Start with the upper two Torx screws .... one is fairly difficult (top, right) :- (get comfortable on your back, with a substantial cushion over the sill!) Now you move on to the REALLY difficult screw! (top, right) Audi have created an access tube through the dash alloy cross-member, especially for this operation! The bit on the Stanley driver is about 12mm diameter and it just passes smoothly through the access tube. You will be able to see the screw and I guided the Torx bit onto the screw with a pair of long reach narrow grips. You just need to be patient! Now, before refitting, clean inside the blower housing and spray a little WD40 (or other suitable lubricant) on the top bearing. Replacement is the reverse of dis-assembly (start with the lower three screws, to hold the blower in place) Re-attach the wires with new tie-wraps. My car is all back now, and it is just great to have that blower working again! Well, that's it .... I just hope that someone else who is looking at this thread, and with the same problem as I have had, will reach my input and find it helpful! BYE!
 
Just thought I'd add to this thread. I've had a squealing fan motor with the blower switch in the "1" position since we bought the car and it has always driven me mad. I finally plucked up the courage to do this today and many thanks to DJ 190 for his most helpful post about a year ago. Without that I probably wouldn't have tried this.

The only things I would add, I managed it without a flexible screwdriver. A combination of a very long T15 bit extended with a drill hex attachment and turned with a right angle hex key got me there. That lot all fitted through the hole in the aluminium beam that DJ mentioned.

Also, to cure my fan noise, once the fan assembly was out of the car I lubed the motor shaft with sewing machine oil and gave the motor itself a quick squirt of WD40. Now, for the first time in 4 years of ownership there's no squeal from the fan motor. I'm delighted!
 
I also some problems with my heater fan. Mainly because there is a lot of snow and wind, where I live right now. The fan and the pollen filter was pretty much full of snow. I solved it a couple of days ago, with a heater. But decided to take the fan out and give it cleaning and some lubrication. This thread was helpful. The hard part is the screw that DJ 190 and iainmd are talking about. I used a ratchet together with an extension and a torx bit. Worked beautifully. There was some black muck on the screws (probably original) which held them in place on the bit.
Here is a photo of the hole the guys are talking about above. This is on a LHD car.

Guess what.....this happened to my fan today.

Had a squeak on the fan yesterday evening and then day, the fan doesn't work. The light blocks come on the A/C dash but then reduce to no blocks when it realises the fan isn't working.

I'll report back tomorrow with details of my success.....hopefully!

Can be changed without the need to remove the dashboard and can be accessed via the removal of the glovebox only. I tend to remove the dash but that's only because I'd be removing that as well. Have got a fan here if you need one.
 
Hey all, this guide is awesome, and slotte Help from this site i was able to fix my blower that was stuck after 500.000 km. A little wd40 and its good to go another 100.000 km. Many Thanks
