I just changed this out on my friend's '99 Contour - super SIMPLE fix. If you look closely at the picture in the previous post, you'll see the module is held in place by one screw. You'll need a small torx head screw driver - not flat head or phillips - to remove it. Once you take out that screw, simply unplug the old module, plug in the new one and screw it back on. Fan should work just fine after that. The module cost about $13.00 at the Ford Dealer.
