My 1991 S10 Blazer had one too. I think it helps to keep the back window clear by channeling air toward it. Interestingly, products like RainX won’t work on old bricks like this or the pre-1990s trucks because the flat front directs air over the cab and not the windshield.
Thanks for reminding me that they used to put spoilers on hatchbacks.
