I have a 1997 Dodge Grand Caravan. I need to replace the driver side mirror.

The mirror will bolt on but there will just be a wire missing in the vehicle's plug for the heated function if that isn't on your van.

You might also consider checking one of the many pick-your-own-parts salvage yards. Part numbers can be relatively useless because they change every time a change or minor improvement is made. "Pull-A-Part" is a very clean and well-organized chain of two dozen yards between Ohio and southern Georgia, and their parts are very inexpensive. A mirror will cost you around eight dollars. You can do an internet search to see how many of your model they have at each yard. There are over 2000 cars at each one.
