Wiper on 1996 Lexus ES300

My Lexus ES300 wiper on driver's side does not come all the way up on the windshield. It comes about 4/5 the way and goes back down. I tried tightening the bolt per suggested solutions on internet. Didn't work. How do I fix this, and what would it cost if I take this to a mechanic to fix it?

We would have to look at the wiper to determine the fix. Most auto repair shops will offer a free estimate.
