What kind of mirror would be for a 1993 SL2 saturn passenger side.

Your mirror is most likely black, just like all the other Saturns of that year. Knowing that, now is it power or manual? Now you go to ebay motors and search for a passenger side mirror of the right color and control. There are lots of them listed and all will fit all Saturn SL models 91-95. There is a little phillips screw holding in the cosmetic piece inside the front door at the front of the window. Unscrew that and you will see three larger nuts, take those off and the mirror will come off. Put your new mirror on the reverse order.
