Auto Air Conditioning & Heater Repair: Air conditioning/heater problems, 2000 buick lasabre, vacuum units

Question
Today my 2000 buick lasabre limited started blowing hot air on the drivers side and cold air on the passenger side...  checked fuses but was not sure which fuse I was looking for...  what could be the problem

Answer
What mechanical work or ANY kind of work has been performed on the vehicle recently ?. As most problems that occur after a recent repair was made can be traced back to the area of where the repair was made as a vacuum line may have been knocked loose or a wire connection came loose, Look around in the area where work was performed.

There are just so MANY possibilities that can cause this type of problem that it is going to take some professional testing of various components in order to diagnose your exact cause.

i wish I could give you the EXACT cause but with all the controllers, solenoids, vacuum units, and various related components, I simply can't without doing tests.
