95 WINDSTAR, 3.8 blend door actuator removal

I have a heating problem. My 95 Windstar is front heating only, no rear heat. Some days I have heat and some days just blowing cold air. I searched the forum and mentioned about blend door actuator. I dig in into the actuator with the help of the threads and pictures in this forum. I removed the 3 screws holding the actuator, but when I try to pull it out, it won't come out. I wiggle it up, sideways left and right, no luck. I know it is loose. It feels like something is holding it from the inside. I don't want to force it out, might create more problems. did I miss something? Any suggestions on how to remove it out?
