Intrigue 99 Air Conditioning

When I turn AC on driver's side vents blow warm air , passenger's side blows cold air.
I never heard about possible problem like that.
Thanks

I know with the 3.5L Intrigue, your symptoms point to low freon, most likely caused by a leak in the compressor. If you look down a few threads, you will see a recent discussion where one of the regulars describes why this happens and the likely cause. My version is the layman, reader's Digest version.
