Great advice Vile!! Wish I had read this thread before I tackled yesterday. I struggled a bit getting the new seals around the vent glass until I decided to use liquid dish soap to lubricate them. The replacement seals I got seemed a little too long but got them to work. My first time so it took me a while to get the seal to seat in the sharp corner. Wish I had had some spray silicone on hand, it probably would have worked better.
