I have a 1998 4 door LT Blazer, my question is this. What years are the rear view mirrors the same. I am talking about the mirrors on the doors. My son hit something last nite. Need a new one. Thanks

There was a design change in 1999 to a stronger mount. You'll need to re-wire the heated mirror and power mirror wires but the mirror itself will bolt right on to your 1998. It's definitely worth the work to re-wire it! Check on ebay, the mirrors are cheap. If you're looking for bolt on mirror, (no re-wire necessary) 1994 through 1998 are all the same.
