2008 XC70 - I have the A/C on set to 68 on both sides. I have cold air up front. I am getting foggy windows from the warm air in the back behind the driver and passenger seats.


I am hoping someone can give me a solution.

 

I was getting warm moist air from the vents in the back.
UPDATE:
1. The vent under the front passenger seat was disconnected.
2. The carpet was damp too.

Solution:
1. Take the trim off the right passenger door and the trim along the side of the glove compartment.
2. Take off the cover below the glove compartment as if you were going to change the cabin filter.
3. Pull back the carpet and the foam will be soaked.
4. About 8 inches below the cabin filter is the black rubber drain tube connected to a white connector.
5. Remove the rubber tube.
6. Take a large zip tie and work it into the hole in the white connector. Push it in and twist the zip tie several times and maybe try to plunge it out with a second one.
7. The AC drain connector has a right angle bend that gets clogged.
8. Reconnect the drain tube to the connector.
9. Shop vac the foam and floor pan as much as possible. I left the carpet pulled back for several days and it's still wet. I put a towel under the foam tonight. I'll keep doing that until it's dryer.

For searching purposes I'll add these terms to the thread:
