My heated steering wheel works, but very limited need to use here in FL.
Is your climate control set to Auto? According to the owner's manual, that will link the steering wheel heating to the overall settings. If the cabin is already warm enough, it will shut off or not turn on steering heating at all. But, you can also override that by operating the steering heater button manually (if in Auto, turn off using the separate steering heater button which unlinks it from the climate setting and then turn it on again). You will know the steering heater is linked as the Auto icon on the climate control display will include a steering wheel icon as well.

I've had other vehicles where there are two differently sized wipers and the passenger one doesn't clear what I'd consider enough windshield area. If you mean it isn't doing a good job of clearing rain and mist/fog even in its pathway, then sounds like there may be an issue with the wiper blade placement or the edge was damaged or got something on it (like dealer prep products) that is causing the issue. If you haven't already, check the blade edge, the angle and clean it off with a microfiber cloth (if you have rubbing alcohol, use a little of that on the cloth).
