2021 Jeep Wrangler wipers, windshield & visibility problems

When driving during a medium snow fall: the front windshield defroster is terrible! Even with the front defroster on high heat, and full defrost mode, the defroster only blows hot air onto the center portion of the windshield. The right and left sides of the windshield get no hot defrost air (no air whatsoever) and snow and ice builds up on the right 12' and left 12' of the windshield. This also causes heavy snow/ice buildup on the wiper blades. Terrible and dangerous windshield defroster design.

I was driving in fog with ambient temperatures of approximately 9 degrees, windshield iced over approximately 2/3rds from the outside in with only the middle of the windshield clear, front defroster only was on maximum, with no air flow to anywhere else, but would not clear the windshield in front of the driver nor the passenger side. Put hand above defrost vents and was only blowing in the middle, no obstruction.
