My 2007 Tundra 4.7 4x4 starting making a weird noise about a week ago. It's been consistent ever since. When I start it up, a high pitched whining noise starts and stays pretty constant, peaking each time I hit the gas. Also noted my AC is barely blowing and isn't producing cold air.
Maybe they're related? Any tips?

Could be your serpentine belt slipping, that might explain your ac problem.
