Ordered part # 19 on parts breakdown (Vent Assembly).I couldn't find a video on how to install the part.I ended up figuring it out myself.You pop off the inner vent cover and that gives you access to the two tabs you release to remove the old vent assembly.When I got the old vent assembly of there was a large amount of white gunk clogging the inner door assembly.I cleaned it all out and installed the new vent assembly and WALLA,the leak problem was FIXED. PS I talked to Nathan @ Customer Service to help with finding the part I needed to fix the leak.
