Default part time light????

Ok still new to the repair thing as well as the jeep thing, I have a 88xj 4wd wouldn't engage tracked down that it was a bad vacuum line under the hood. HOWEVER now my part time light will not go off. Lifted front wheel off ground to see if it was disengaged and it was, so what could cause this light to stay on ALL THE TIME. any help appreciated, and keep in mind I'm new to mechanics so lamens terms appreciated lol

Vacuum switch rear of transfer case sounds like its sticking . Should be right near speedo cable . Rear drive shaft area.pull the vacuum line off top unscrew it and see if ball on end move freely.If not spray penetrating oil and free it up.
