Reverse lights not working/access to the NSS on a 32RH 1998 TJ
Ok, I am posting my solution to this, in the hope it helps others. It seems a bunch of people say its easy to replace but I did not find anyone offering how they did it. So to figure out this mystery I had to go through the hard knocks.
Issue is that on the 32RH transmission the switch is so close to the drive shaft that there is no direct way to access it.
My reverse lights did not work when in reverse, they did work if I pushed REAL hard on the gear shifter towards park. It started getting to the point that even if I pushed real hard they did not work.
With the engine off I would push the thumb button and slightly jiggle the gear shifter back and forth while slowly moving it forward. I would hit point where the lights would come on, but the shifter was between reverse and park.
After I adjusted the shifter cable per James's suggestion. My shifter was much tighter. Thanks for this suggestion, it fixed that annoying issue. but the lights would not work at all now.
After a lot of trying,and swearing, to get at the switch with various wrenches and sockets. I figured that the drive shaft needed to come down more. Since I had some JKS sway bar disconnects that i removed from a previous jeep, before selling it. I went ahead and started to put them on. Half way through the process I raised the jeep by the frame so the axle would droop. Much to my displeasure it was not enough. I did not want to drop the belly pan, thinking, “Am I supposed to do this in the mountains if this switch fails." So I was determined to find a way to do this with what I would have while off-roading.
I found that if you have disconnects or other sway bar mods this is probably easy, but not for those still unblessed with suspension lifts, either by choice or funds.
SOLUTION: If you go get a 1" crow foot wrench, I got mine at sears. Yea, yeea, they were the only one that had it in stock. Lift the jeep near the belly pan, but at the frame. I have a high lift jack and a lift that is powered by the exhaust of the engine, but for safety I used a floor jack. Now you will just barely be able to get the electrical plug off with your hands. Mine was facing down so I used a tiny screw driver to reach up between the drive shaft and the tranny, push on the catch and pry it off. Now the delicate part, reach over the drive shaft and find an angle for the crow foot to slide on and very carefully align the socket wrench. Once on turn away! Going back on the way. Attaching the torque wrench was the most frustrating part. You can only turn the switch a little at a time before repositioning the crowfoot. Took a few minutes to do with this wrench, and a lot of dropping the wrenches.
I don't think you will need to disconnect anything to do this, if you use the crow foot wrench!
I'll post pic of my tools and view of the switch.
