I haven't had the window problem, but have had everything you've mentioned and much more. All have been fixed, mostly by me with the help from info gathered on forums such as this. Things settled down at approx 95k miles. Now at 150 kmiles, I'm a fairly happy camper.
If you are at the mercy of others to fix your car for pay... you may want to get rid of it.

Otherwise:
I would suggest getting the actual alpha-numeric codes.
I would suggest getting elect diagrams and shop manual from helminc.com. ... if you intend to keep the vehicle.
The blend door actuator is replaceable. The blend door is repairable.... you'll need instructions and a full day( if you are slow like me) to repair it.
