My dad had this problem on his <censored> truck. It turned out the truck had been wrecked, and the PO (or some shoddy body shop) had attempted to wire the thing up themselves... it took us a full afternoon to get it figured out. Incidentally, when they say not to touch the halogen bulbs because the burst, they mean it. I have the scar 1/2" from my eye to prove it. (Don't worry about it on the headlights on these Cougars though, just those little halogen "inner bulbs" that modern cars have.
