I am trying to locate a front driver's side water leak in a 2001 RX300. I need to pull back the carpet but cannot remove the darned footrest. Does anybody know how to do this? The Lexus repair manual merely says remove footrest - install footrest, with no directions as to how to do so. Huntsvill Lexus says it is bolted in. Can't find any nut or bolt. My brother who is a mechanic says it should slide on over a flanged pillar. Help! Thank you.
