Saturn ION 2 rearview mirror is still fully attached but when you move mirror into a position it will not stay in that position.

Time to replace the mirror...the circulating ball must be jammed or worn out...At the bottom of the mirror head that attaches to the windshield is an allen screw head or small Phillips head...this must be loosened for the mirror assembly to pull off of the windshield...Best bet is to try your local salvage yard for a Saturn replacement..."Pic A Part" is a national yard...You should try working with an old mirror so you don't damage your current mounting...of course if the windshield magnet comes off, it can be re-attached with mirror adhesive glue...parts stores and auto dept at Walmart...Hope this helps.
