1998 Buick Park Avenue 6 cylinders 3.8 The A/C doesn't work properly. Cool air blows on driver's side and hot air blows on passenger's side. There is also like a clumping sound like opening and closing a vent that occurs when the car is turned on. Checked the freon and it is fine. - Visitor
Temperature blend actuator on drivers side failed, and replaced. Easy DIY fix for a handy guy. Now the actuator that selects between windshield, mid, and floor is out.
