Smell in 2003 Toyota Matrix after a windshield replacement?

I have 2003 Toyota Matrix. Few weeks ago I had the windshield replaced due to a crack. After the installation the car had a stong smell of what I can only describe as a chemical/sweet smell. The smell has continued even after the windshield company came, took out the windshield, and reinstalled it, using a different glue! I also took the car to the Toyota dealer to have them check the AC system and heater core. They did not find anything. 218 dollars later still have the smell and it gives me headaches when I drive the car. I don’t know what to do! Help anybody!
