I have had an ongoing electrical gremlin for the past 5 years with my 97 Diamante. We had a Jericho (inland Hurricane) in Marion, IL this past May and the ins co, paid for the damage to my car, all superficial, so, I took it to the dealership to find the problem which I could not. They found it to be the auto-dimming mirror to be a constant draw. Cost me a pile to find that out too, aack. I am in the middle of resurrecting the car to reliable status, new tires, brake caliper(stuck), valve cover gaskets, "Y" front exhaust pipe, battery and now to fix the engine oil leaks. Coming back to this forum has hopefully, led me to the fixx, wish me luck.
cheers,
Kevo
