You shouldn't have to remove the glass. On most vehicles you can remove the regulator from the bottom of the glass carefully so the glass doesn't drop. Then carefully lower the glass into the door. There are plenty Of YouTube Videos ..even if not for your model vehicle all of the basics are the same.

You need ventilation flaps calibration. Also one of the flap servos might be broken.

There are actually 3 seperate places for fuses. If you need to replace for the driver or passenger 12volt, its located inside the cabin, open the door and look at the actual side of the dash, there you'll see the fuse box. If its the 04 xc90 it would be fuse #11. If its for the cargo area, its located on the drivers side also just inside the frame almost behind the brake light, # 7. Hope that helps, I ran across the same issue, just wanted to charge my phone.

Check for corrosion in the plug for this head lamp. Wiggle the wiring with the light on if it blinks there is a bad connection.

you should start by checking your alighnment

Check the brake light switch, this can sometimes fail and cause the autobox to lock in park (you need to depress the brake pedal to get out of park)

I had this problem as well in my 2005 XC90. It turned out that it was switched on audio. Use the remote to switch back to DVD.
