The weatherstripping needs to be replaced. I have attached a photo which shows the weatherstripping. I measured the bulb portion of the weatherstripping with a micrometer and it is approximately 0.225 inch. It is quite brittle, and I suspect the new replacement might measure larger.
I measured the portion that inserts into the slot in the window and, at its widest point, it measures approximately 0.1 inch.
Do you have a replacement?
Thanks!
