Are 1994 and 1997 ford taurus parts compatible ?

they should be. r just rule of thumb when looking for parts is 3 yrs up and 3 yrs down. its always worked for me on all of my cars,

Other easy way ( but may sometimes not quite be right ) is to go on line and look them up for both years and compare part #s. OR making 'friends' with your local ford parts guy (wouldn't hurt to buy a part or two from them either).
