My girlfriend drives a 2001 Wrangler Sahara 4wd with a 4.0liter and an automatic transmission. Recently behind the wheel i needed to put it in 4wd and opted for low range for the gears holdback on a downhill, but when i pulled the shifter back to 4lo the dash still read part time. There was no holdback either as if it was still in 4hi. I looked underneath and all linkage is still connected and it steers like its in 4lo. Is that the way this series of jeep is supposed be or is something wrong? On the dash beside the part time light it has a 4 Low light and a Full Time light but neither came on at any time? Thanks for any input i recieve, Sam.
