My contour overheated on my roadtrip last week during springbreak. However I knew exactly what the problem was--the blown fuse for the fans. I temporarily stole the fuse from the ABS to make it home. I knew it was the fuse right away since I had blown it a few weeks prior after I clogged my fans with mud after doing some offroading. I had to replace the entire fan assembly cause after the mud froze, it cracked the housing to pieces and the fan motor was all clogged up. But you even said yourself that your fans weren't coming on. I know it wasn't the problem with yours, but jesus, all that trouble when that's what it could've been.
