I was just quoted $100 for a guy from a auto glass shop to come out, remove, reseal and re-install my back window. Or $300 for a new one. He also said the plasitc cracked trim on the INSIDE has nothing to do with the window leaking. He said its a glue in/ bolt in window and the plastic trim on the inside is just beauty trim or something like that. I duno, but i dont want to just throw some silicone on it and call it good so im going to have it done right i guess. Does anyone know for sure if that trim is actually part of the seal? he didnt sound completely confident. If you ask me, by looking at it, that plastic moulding is a part of the window and if cracked could leak.
