I am pretty confident with that kind of wattage that there isn't a shop in the world that would try and run it off of the factory wiring harness. Should be easy enough to tell by looking at the amp or in the engine bay to see if they ran a new power wire.
Sorry, typo... was thinking fast than I was typing. If I recall my light comes on right around that 45-50 miles to empty time frame... 2 gallons at ~24-26mpg = ~50 miles. With a fill being a hair over 18 gallons typically.
Basically a spoiler on the blade that the wind hits and pushes against the glass...
I stupidly replaced mine with aftermarket ones and they do not work nearly as well. Next time I am at the dealer I am grabbing a pair.
The OEM blades are usually the best ones in my opinion... Either that or go with a high end blade. Maybe something with the air foil as mentioned? This would keep the blade tight to the window.
To rule out the wipers I would remove the blades and take it for a spin. If the noise is gone I'd say that is a pretty good indicator that the blades are your issue. Wrap the arm in tape or something to avoid damaging the windshield.
I would be pretty upset as well... Have you tried contacting chrysler yourself, or seeing if there is a reasonable dealer around that can talk them into the repair?
These are standard fuses on all new vehicles and should be available at any auto parts dealer... Seems to me your parts store is the one who sucks in this equation, not the manufacturer who is using the standard fuse.
I've never removed the lower grill, but the upper grills are just pushed in... There are tabs that you carefully push the side to allow them to push through the mounting holes from the back.
