I was replacing my windshield wiper motor (after asking about it here) and while putting in the new windshield wiper motor, I hit it on the edge of the windshield causing a few cracks. I asked a couple people about fixing it. The one person told me to put silicone on it, while the other person (a windshield repair guy) told me to not put silicone on it (because the acid in it will eat away at the car) and that there's nothing I can do except watch the crack get bigger. I'm wondering if there is any way I can fix it? And if there's nothing I can do now, is there something I can do if cracks start to appear? It is a new windshield and I really don't want to replace it again. Also, it's a 2003 Toyota Camry LE.
The windshield repair guy is correct: there is no way to repair cracks in the windshield. I don't know what the laws are in Alberta, but here in Virginia, if the cracks are on the driver's side of the windshield, it needs to be replaced. Considering that you were replacing the wiper motor and it is on the DS of the vehicle, I will assume this is your case. I will also assume you are still experiencing cold nights there in Alberta, so night/day temperature differential will expedite the cracking which will occur.
For edification purposes, if a windshield has a bullseye type rock impact site, these can most often be repaired by windshield repair person. This can occur even if small cracks occur around the bullseye. Your situation is much different.
