1: I'm not sure, but when the car is cool, do the fans turn by hand freely? They do fail eventually and will take more juice to turn & blow fuses... One of mine froze once and stopped working, however the fuse never blew so I may be off on the cause.
2: If you remove the wiper arms and the plastic pieces at the base of the windshield you'll see a round rubberish cap that unscrews from the firewall. You can puncture a hole in that cap and run the wires into there. I did. I used a razor knife and cut an X into the cap, then pushed the wire through. The X resealed itself pretty good against the large Amp wire and I've never had any leakage or any problems at all. Like I said, the cap is a rubber type cap that unscrews. Just push the wire through, comes out a little above the break pedals I believe.
Good luck!
