hey guys i have a 02 town and country... and i have charged the ac up to about 42 oz's and got cold air in the back.. but fair on the passenger front and warm on the drivers side... i have found alot of research on it possibly being the blend doors.. but i dont know where they are and would like to disconect the linkage and manualy open and close to see if this is the problem...

does anyone know a easy way of doing this?
