The 4x4 light is controlled by a switch in the transfer case. It's relatively simple to replace.

Is the Map sensor working?
what happens when you try to drive it or give it gas?

I've been looking for awhile now I can't seem to find anything for my year of jeep. And well I have a 95 xj and my heater resistor needs replaced. And I've never messed with my heater before so does anyone have a writeup on how to replace it? Or can anyone give me tips? Or really anything.

Nothing bad. It runs smoothly, no stalling, no issues moving...no trans issues. It's my daily driver so yeah.

non HO to HO motor swap no start
hey guys
hope I am posting this in the right spot. I have a 1990 XJ 4.0L and swapped the motor to a 91 HO block and head reused my 90 intake, exhaust, distributor, alternator, coil. My jeep was sitting for a couple years with a blown 90 block and recently swapped the 91 HO. I am getting no spark, checked the coil, ignition module, CPS, and don't know what to do next. If anyone has any ideas or has dont this swap any help would be appreciated. And does anyone know what the fuel injector looking clip on the bottom side of the intake with the O2 sensor plug goes to?

FWIW, mine would idle normal at initial startup. I noticed the high idle when shifting back to park when I was getting ready to shut it off. If I did shut it off and immediately restarted it, the idle would usually return to normal. If I drove it around for a mile or two, it would jump back up.
Good luck.

on the front wheel bearings many have said you need to replace the whole hub assembly. but autozone sells just the front wheel bearings and the whole assembly. so can you do just the bearings or not. or is it just not worth doing just the bearings
