Thanks all.....I appreciate your feedback and advice on this.
I was definitely confused when they said there would be “electrical problems”.....my simple brain always thought that REMOVING something from an equation made things easier.....apparently not in this case....??
When the new window comes in, my service dept will book their “glass guy” for installation. Does the “glass guy” just stick the window in/on and then hand it back to the the service dept so they can do (hopefully) the GMC-specific stuff (replacing the gaskets, nuts, washers, sealant, etc because the spoiler was removed)? I’ll be asking these types of questions when I call my service rep early next week to touch base and set up an installation appointment.
As always, thoughts on this are welcome. Thx.
