: 2000 catera defrost

I recently had a aftermarket cd player put in and after that its seemed that the defrost is making a high pitched noise and is not working like it was before. The car will get foggy real easy. Does ANYONE have any idea's ? Please help cuz im riding with a newborn

Just last night, a chilly one, my driver's defrost and dash vents were blowing cold while the passenger's were blowing hot. A look around the forums suggest an air mix valve of some sort since the source of heating and cooling should be the same for both sides. I am researching now and will let you know what I find.
