blend door actuator help
Hello my friends! When I start my '04 320 i get a steady clicking noise, like a slow count metronome, for about 2.5 minutes and then it just stops. After using some google-fu and asking about I think I have an issue with the blend door actuator. I don't have any issues related to heat or a/c not moving correctly just the silly noise letting me know it's a ticking bomb to certain explosion (kinda like my samsung note 7 was). However a search for this in the 209 forum doesn't get me anything. Of course this could be user error. So does anyone have experience with this repair in the 209? A DIY or link to a DIY? Or maybe the WIS so I can get completely confused. Or if this is not something to tackle then I get that as well.
Thanks for the help in whatever form!

You really need to pull codes from the ACC to determine exactly which servo is failing. A generic OBDII scanner won't do this - you need SDS or iCarsoft or something that reads specific MBZ systems. Once you find exactly which servo/ flap it is, we can help with WOS docs. Hopefully it's one of the easy ones.

if you are going to DIY on this car, it is a good idea to invest in a scan tool. Check into iCarsoft i980 - it can be had for just over $100 and reads and resets codes form all the car's proprietary systems. You can get SDS for around $250, but you'll need a laptop and some pretty good computer/technical skills to install and use it.

I have discovered from scanning that it is the right side footwell. At least that is what the scan says. So hopefully this will help with what I need to fix the click. Also Rodney thanks for the tip on iCarsoft, that's a great benefit and will save me on the cost when I use it a second time as a scan at a shop is 90-100$
