Hi everyone, First time poster here. I just purchased a 2000 Dodge Intrepid 3.2 ES with 141,000 miles on it. It's been abused some, and it is a first car for my 16 year old daughter. The AC / Heat blows through the vents, but won't switch to defrost or any other setting. When I select a different setting, it will light up like it changed but doesn't. I'm wondering if there is a way for me to manually switch the blend door so it's stuck blowing through defrost vents? Or if the fix is simple, I'd do it. Thanks for this awesome forum to help me with this new project!
