There is something that I need to look at on the actuator. It makes a loud hissing sound where I believe air is leaking out causing the other doors not to function properly. I need to find proper tools to remove my door speakers. Then I wil have more hand room to take out the actuator. I believe that there is a hole in the rubber part of the actuator where it leaks air. When I move it.. it causes a louder hissing sound. I will find time later to take it out.. and find the source of the leak. If it is a hole.. then I hope that some bicycle flat repair kit will take care of the hole.. if it turns out to be a hole. Thanks anyways.
