how do you check blend door for drivers side with dual climate control on 2003 Buick LeSabre

air conditioner works fine but drivers side blows warmer air than passenger side. I suspect the blend door.How do I get to it to check out.

The lesabres are famous for this when the freon gets low. Have the a/c system checked.
