Glad I could find a Blazer forum & ask this question.
When I press the Glove Box button to open up the glove box, you can hear it unlatch, but it does not fully open.
It looks like the door of the glove box gets caught somewhere on the right side, where the passenger door panel butts up against the side of the glove box.
What I've found is that I have to push inward from the right side of the glove box to get it unstuck from the door and pull down to get it to open.
Is this a common issue with the Blazer, or just mine? I'm curious.
I have a 2020 AWD RS model.
