Cold air comes out from the blower on the driver's side, but the air coming out from the passenger side blower is abt 15 degrees higher. What gives?

Is the airmix turned up?... Not sure if they have it s70's, but it was in 850's and it mixed in fresh air. Might not be it, but just a thought.

I closed the vents to prevent outside sir from coming in, I turned on the recirculation function. This has never happened before, only recently.

My airmix is also closed. We run the A/C on recirc. all the time because of the extreme heat and high humidity here on the gulf coast. Local service techs recommend it, to prevent the sysem from working so hard.

Our S70 seems to have equal output on both sides.

Airmix and recirc are different of course. Every now and then you want to turn off recirc so you're not constantly recirculating stale air. Down the road you might get some mold build up. Not highly likely, but just a good preventitive measure.
