Eh. I'm just in a funk because I broke my new toy and have to make another one.
You are right in thinking the grill block was too much. The electric fan on a car is a major power draw(Volts * amps = Poor Mileage) don't get discouraged. You just found the point that is too much. Try opening it up a ways to give it a little air. Leave yourself a good 4-8sq in for starters and you'll see much better results. On my Jeep I've found 4 out of the 7 grill slots is a happy medium.
