The climate control on my audi a4 1.8 avant estate doesnt work. The digital display works perfectly fine but no air comes out at all
Hi Michael. You don't say what mileage your car has done, but if you use the heater blower during normal UK winters, it's a strong possibility that the blower motor has packed up, (check with a new fuse first), or that the carbon brushes have worn down so far that they no longer have contact with the slip rings of the heater blower fan. This could show itself as an intermittent stop-starting of airflow which would maybe come and go with increasingly longer periods of no airflow until it finally fails to work at all. If you haven't tried it already, set the control to demist and give the NS door (nearest the blower motor) a good slam shut just as the LED lights on the display start climbing up. This may jolt the blower motor into turning.NB this is not a permanent fix and may cause other damage if used regularly!!! A new blower motor (OEM apparently) will cost about £65 inc delivery from ebay (the 'real' price seems to be about £130, God only knows what the labour charge would be). The brushes are available separately for under a tenner inc. postage also from ebay. It seems that this is a very common problem with A4/ A3/ Passat blower motors which have reached the circa 10 yr old mark. Fitting the brushes is about a 1- 2 hr job if you are prepared to do it yourself, and involves removing the blower motor after removing the glovebox by accessing the hexhead screws on the panel at end of fascia, with NS door opened. There are a few forums with good pics of this if you have a search. The carbon brushes are a commonly widespread standard size and fit a lot of VW Audi models. You need to weigh this up against the cost of a new blower motor, and how much of your own time you want to spend on the project, but none of this is very difficult; even soldering the brush contacts is a very simple job if you have ever used a soldering iron. If you don't own a soldering iron, and will have to buy one, or if you don't consider £65 too much to pay for a new motor, it would be a simpler job to replace the blower motor and avoid the brushes and soldering job altogether. I have heard that reputable auto repairers would ask for around £200-£250 to replace the heater blower motor, which is not dreadfully unreasonable if the parts cost is £130, but less reasonable if they are paying £65 for the part....Best of Luck.
