The Part Time Light of Jeep Liberty reminds the driver that his Jeep Liberty is in Part Time 4WD transmission mode. When you change your driving mode to 4 Wheel High/Low, you will see the light on the lower left side of your instrument panel.
However, as the Jeep Liberty becomes a decade-old vehicle in 2023, many users are facing not turning off the Part-Time Light problem even after changing the mode.
Are you one of them? If yes, worry not. Here I will discuss all about the Part Time Light in Jeep Liberty with the solution to your Problem. So grab a cup of coffee, and let’s jump in.
What’s a Part Time Light? & How Does It Work On Jeep?
To Put it simply, Jeep Liberty’s Part-Time light is an indicator to remind you of your car’s driving mode.
For the past two decades, every Jeep Liberty has come with Command –Trac. So you get 2WD, neutral, 4WD high range, 4WD part-time, and 4WD low range positions to drive your Jeep Liberty, which you can manually turn on and off.
Some Jeep Liberty models, like the 2007 Jeep Liberty Sport or Jeep Liberty 2004, also have automatic four-wheel drive mode. And for those models, the Part-Time Light automatically turns on when Jeep Liberty’s system detects wheel spin and shuts off when not needed.
For example, I was driving my 2007 Jeep Liberty Sport in the rain, and one wheel suddenly slid a bit. Then the Part-Time mode kicked in without delay and transferred the engine power equally to all 4-wheels.
Also, when it turns on, Jeep Liberty’s system locks the front and rear driveshaft, helping you to navigate challenging road conditions.
However, sometimes Liberty’s Part-time light gets stuck, and no matter what you do, it doesn’t turn off. But why does it happen?

Why Does The Part-Time Light Stay On In Your Jeep Liberty?
Usually, Jeep Liberty part-time’s light turns on, and stacks when you have wiring issues inside the car or the Transfer Case switch stops working.
In this portion, I will describe both reasons in detail so that you can understand your problem better.
Here’s the reason the part-time light stays on in your Jeep Liberty:
The Jeep Liberty is a more than 2-decade old vehicle; even the latest Jeep Liberty was released in August 2012. So it’s quite common to have wiring issues with Jeep Liberty.
And when the wire connected to your Part Time Light becomes faulty, the indicator/light will malfunction. When that happens, you have to replace the wire to fix your issue.
The Transfer case changes your Jeep Liberty’s driving mode from 2WD to 4WD by transmitting engine power to the rear and front axles. However, the Transfer Case Switch of the Jeep Liberty gets worn out after using it for a couple of years.
And then the can Switch easily gets stuck every now and then and makes part-time light on permanently.
Though the Part-Time Light stays On for any of the reasons above, faulty Transfer Case levers are the main culprit most of the time.
But how can you fix the issue? Read the following section to know in detail.
