On my 2005 full doors, the word LOCK is on the rear of the switch. On the half doors, LOCK is on the switch front.
I have my 2005 on record at Rock Auto and Amazon, so when I looked up "TJ half door handles" it steered me to what I ordered. Never once did I think they'd be different. I looked at the full doors when I referenced the locks. I even cross-referenced Dorman (what I ended up buying) and found different interior handles by number. Again, I thought of the Jeep's vintage, not the doors and clicked that order button.
I did all that before I bought because I was confused by the NUMEROUS online reviews people left saying the word LOCK was on the wrong side of their handle. I chalked it up to spotty/cheap production on those handles.
Tonight I was fiddling in the garage and looked under the rubber seal on the old early-style mirror I'd removed last weekend and saw a sticker with a 1997 date. I was like, "Oh this might mean I have to consider different locks when I get it re-keyed." Then I thought wait, maybe this explains all those backward handles. And of course, they are, indeed, different.
I got one at Rock Auto (driver) and one at Amazon (passenger). The passenger was 3x the cost of the driver, but still lower than the Rock Auto passenger. So it should return easily and fund BOTH correct driver and passenger. Both of which end up about the price paid for the driver at Rock Auto. (That return will be trickier, I'm guessing. Or I keep it for my 2005. Also an option.)
