Ac fan not blowing as strong as normal
2020 impala my ac works fine for about 30 minutes then after barely blows any air out. Still gets cold and hot just fine the fan just gets much weaker.

The Chevrolet Impala is a large sedan, one you might consider if you’re in the market for a Dodge Charger, Kia Cadenza, Nissan Maxima, Buick LaCrosse, or Toyota Avalon. It gets a few changes this year.
The 2020 Impala comes in LT and Premier trims. The LT gets 18-inch painted wheels, an 8-inch infotainment system with Apple CarPlay and Android Auto integration, a partial power driver’s seat, two USB ports, dual-zone automatic climate control, a leather-wrapped steering wheel and shift knob, and heated exterior mirrors.
Select the Premier and you get 19-inch wheels, LED daytime running lights, HID headlights, a dual-tip exhaust system, chrome exterior appointments, perforated-leather seating, keyless access and start, remote start, an 8-way power driver’s seat, heated front seats, and navigation.
Only the 3.6-liter V6 returns for 2020, putting out 305 horsepower and 264 pound-feet of torque. It drives the front wheels through a 6-speed automatic transmission. Fuel economy for the single engine is 18 mpg city, 28 highway, and 22 combined on regular fuel, and 14, 20, and 16 when running E85 ethanol.
Other than a reversing camera, no advanced safety features come standard on the Impala. The LT with Driver Confidence Package gets you rear park assist, blind-spot monitoring, rear cross-traffic alert, and lane-change alert. That same content, along with forward-collision alert, comes standard on the Premier. The Premier Driver Confidence Package comes with automatic emergency braking and adaptive cruise control. When tested by the Insurance Institute for Highway Safety (IIHS), the 2020 Impala scored an Acceptable rating in the small overlap category and Poor for headlights, but Good everywhere else.

Why is car beeping in parking shft?
The MPG is wrong on all of the 2019-2020 impalas. It says 14c/20h 17 combines. It should be 19c/28h 25 combined.
