Won't take you more than 45 minutes. Use a phillips to remove the plastic trim around each of the two openings where the top latches to the windshield. Now the top cover can slide back to expose the hydraulics. What you should find is that the hydraulic cylinder which actuates the lock is causing the leaking. Disassembly from this point should be intuitive. No need to bleed the system when you finish.
Finally, consider talking to Phil at *****************
http://www.*****************/parts_lobby.htm about purchasing the hydraulic cylinder. He sells them for $125 each. Ask for part #129-800-16-72. Might as well get two of them and do both sides, since these are notorious for failing.
