Adjust oven rack to highest position or approximately 5 inches away from the broiler element and heat the broiler.
Brush corn on all sides with the olive oil and transfer to a foil lined baking sheet.
Broil the corn until well-browned on one side, about 10 minutes. Turn the corn over and broil until browned on the opposite side, about 10 minutes longer.
While the corn broils, stir the mayo, cilantro, lime juice, garlic, Santa Fe Seasons Chile Blend, and ¼ tsp salt together until uniform. Stir in the crumbled Cotija cheese and set aside.
Remove the corn from the oven and brush the corn on all sides with the mayo mixture.
Return to the broiler and broil the coated corn until the cheese coating is warm and slightly brown on top, about 1 minute then remove from oven.
Season with salt & pepper to taste.
Serve with the lime wedges and any remaining mayo mixture.
