Hi Scotty, I would love to hear your thoughts on this:
I drive a 2014 Ford Fiesta (104K Mileage) with an AC system that make a brief "knocking" noise upon ignition, which goes away after 10 seconds. Every time I turn off the AC system after using it during a drive, it makes the same "knocking" noise for about 10 seconds and then goes away. The AC system started doing this about 20K miles ago, and it still seems to work fine at this time.
What do you think might be going on with my AC System? Is it on its way out, does it just need a recharge, or do you think it's something else?
Thanks for you time, and I hope to hear from you soon!

That is the blend door actuator. You're going to have to replace that part. Your ac compressor isn't going out and it doesn't need a recharge.
