No joke. You read that right. A gecko crawled in and got fried and shorted it out. Wierd contaminants like random reptiles will shorten alternator life or cause intermittent charging. Just get it checked out at vatozone, advance, etc...
Soo... call Geico? Should be covered... lol!

Nice but killing their annoying mascot probably gets a call from their legal dept.

The switches on either side of the steering wheel? My laredo has four switches, fog lights, rear window wiper, rear window defrost, tranny power/ comfort modes. Not sure if that's what you're asking about

Yes 97+ I guess I should have been more specific. Sorry. Yes the defrost, rear wiper, fog light, extended idle. Not the switches them selves just the bezel or panel. Im sure some of you have seen them even been a few for sale but I think the last one I saw went for 200$. I have a friend that lives in Germany. If I could find the factory part number I could have him see what he can find. He was intrigued by the possible scavenger hunt. I only need one so any I can get past that will be sold for what he and I have in them. Well thats the plan anyway.

Hypothetical question:
If someone wanted to make a Jeep primarily FWD instead of RWD, could that modification be made to an NP231? Or would the internal configuration fundamentally prohibit that?

modification like removing the rear driveshaft? I took apart enough 231's to see that there is just a simple chain driven by a mode collar on the main shaft. U can just leave it in 4 high and remove the driveshaft. Longevity is a question though. I do know few who drove fwd for months and didn't have issues except for when turning because of the U joint binding

The NP231 is a box of shafts and gears. You can't change its behavior. The easiest thing would be to get a twin-stick transfer case like a Dana 20 and disengage the rear. If you really want to keep the NP231, one option would be to put some lockout hubs on the rear axle, but that will depend on whats back there (its an option for D44, don't know about others). Maybe some kind of clutch on the rear output shaft if you are want to actually fab something from scratch.

1996 is a tough call because you could have a totally random PCM - OBD-I, the special '96 PCM, or later OBD-II. If it's the same PCM as a 1997, then yes. These would've been built at the end. Most PCMs is 1996 model year XJs won't have the extended idle option.

Nope. The front output chain is driven by the main shaft. Unlike mods like 2L and 4:1, which basically replace parts or make use of things that already exist, modifying the way the drive sprocket is powered would require a total redesign and possibly some extra length. Also the speedometer/VSS is driven by the main shaft, so it'd need to stay turning anyway. You could potentially rig something that can disconnect the rear propeller shaft from the transfer case output but then you'd have to deal with the chain stretching.

Much easier to get a transfer case that can do that already

That's what I've been doing, and that's why I was curious. Just a what-if question
