Perfect fit, no issues! Thanks 1A Auto!
Installed myself on my 2013 Audi Q7 and it works well!
If youve determined that the blower motor is your issue, but this and replace it yourself. Did it in a 2015 Audi Q7 with about 55k miles. Apparently its common for them to go out around that mileage. Saved a TON of money doing it myself. I dont know anything about cars but decided to do this. It took like an hour maybe. You just unscrew a total of about 13 screw, take old part out, put new part in, put screws back. AC blows air again.
The fan was as described and arrived quickly. I was impressed at how well it was packaged for shipping. The fan fit my wife's 2015 Q7as well as the factory part I removed. I was a bit concerned at first because the build quality didn't seem to be as good as the original but it is working fine and has been for a while. And since this was by far the best price could find it is worth a try.
AAA+++ ... Fast, Precise, Pleasant, Cost Effective... I got the Best price under best possible transaction ... The part works perfect ... This is from a first time buyer ... very pleased ... Why go anywhere else ... Thanks
Great price! Easy install using the video. I save about $500! Thanks and I will continue doing business
Could not find a video on the install but I got it done. The fan and resister took minutes to install just like original parts. Took hours to remove lower dash to install part's. I would have been very disappointed if they didn't work or fit,but they did. You guys and ladies have never let me down. Thanks again. Leopold
