Just having the window reset with a new gasket if the window isn’t broken .. is that what I understand ? I don’t think the insurance will cover that .. they will replace the window and the gasket it it’s bad if it’s broken chipped cracked more than a certain size ( silver dollar) otherwise they will patch the glass unless it’s in front of the driver.
It sounds like you just wanted a new gasket and reset that’s not covered by insurance and they were trying to find a reason to “help you out “ and have the insurance pay .. like saying a rock hit it right? Hint hint ! I have known people who enlarge a crack just so it gets replaced ..
doesn’t make it right but it does happen ..
Otherwise it’s your dime to pull the window and if they break it ( very possible) that’s also your dime about a grand or more.
