I need to know how to change.
Answer Hello Joe! Pull the old gasket off. The new gasket will press into the door liner. It may be best to soak the new gasket in warm water to help take its shape/form You may need to use a hair dryer to form the seal, be careful not to melt it. Hope this helps!
Does part number ap4315965 fit my model?
