So I had my windshield replaced on tuesday for like $214.....
The messed up my weather striping around the doors... there are two small saggy parts... but

Now when it freezes, there is frost on the inside of my blazer... I assume this means theres a leak.... which with my previous windshield this did not happen, even with the crack....

Should I call them back and tell them to replace it again and fix the leak?

 

Hell yes. Call em up, tell them that post windshield repair you have had moisture and freezing problems, and that you think the seal they did is no good. They should honor their repair job and fix what ever went wrong free of charge. if they start talking $25 roll out fee etc, then it's time to play hard ball....

I would say that if it was done 2 days ago, and there is already a problem, it is on them, and they will honor that though. I would call sooner rather than later too...
