Here's a tip for anyone who needs to R&R a HVAC box on a 2010 to 2012 Camaro for heater core, evaporator core or door repairs. For your first step, call the glass man and have him remove the windshield. At some point in your repairs, the windshield will need to come out as two very long bolts on either side run vertically into the support beam and cannot be pulled out as the glass is in the way.

If you have the glass removed first, you can work from the outside and inside and get it apart easier. After it's completly reassembled and tested, call the glass man back to reinstall the winshield.
