Is it possible you have the passenger controls adjusted higher or lower? This is a split system, after all..

Your low on freon... it's one of the well documented quirks of the split zone A/C system in your Deville. When the freon is low the drivers side blows warmer than the passengers side.

I suppose when you said "why do the driver vents blow warmer air than the passenger vents", I should have asked, how much warmer? The passengers side temp control will only vary the temp about 4 degrees.

I had the same problem, and I was convinced I had some major problems, but a $7 can of freon took care of it.
