a quick poll for everyone. Does your 4X4 indicator light work on your Jeep?
I think about the Jeeps my family has (and has had before) and not one worked correctly.
my '89 YJ - Light will turn on after about 20 minutes of being in 4X4, then it'll stay on for 4 days my sister's '97 ZJ - doesn't come on my mom's '95 ZJ - nope my brother's '98 ZJ - sometimes says PARTTIME when it's in Full Time my girlfriend's '99 WJ - Says PARTTIME no matter what 4X4 mode your in, then stays on until you turn the car off even if you put it back into 2wd my mom's old '85 XJ - the light would come on when you started the car, but wouldn't come on when you put it in 4X4 my father's old '86 XJ - Came on right away, but would stay on for days after taking it out of 4wd
