Hey guys new to the scene not long got my honda civic ma 47k miles Had a issue with the driver side window coming out of its rail. And now goes back up at a angle. Managed to close the window while forcing it back it to place. A few people who own hondas around me said it should be a easy fix. Took it to a garage today. They stated that all the mechanisms work however the rubber is destroyed from age , and that the guidance rail is also destroyed. This car has never been in a accident and was working about a month ago. They suggested I get a new door . I'm going to give it ago myself any tips or guides to do it would be wonderful. Or if its just worth getting a new door. Thanks
