4LO light flashing?

So a girl in my office has an 08 Liberty and asked me to help her figure out her 4WD, she has a switch with 3 settings - 2WD, 4WD Lock, 4LO

So took her out in the snow to show how all 3 settings work, differences, etc.

But when it's in 4LO, the light is flashing, and its easy to tell it ain't in 4LO.

Does the flashing light mean somethings busted? Not that she's every going to need 4LO anyway, Im just curious about it now.

I believe the flashing light (4LO) indicates that you have selected 4LO, but that 4LO is not yet available. To get into 4LO, stop the vehicle, shift into neutral, select 4LO, then put it back in drive (or reverse). At least that's the way it work on my 2011 automatic Liberty.

Hope this helps - Roger

4Lo is a true gear reduction...have her read her manual, otherwise she is going to do some serious damage to her drivetrain at some point. You have to put it in neutral in order for the transfer case to engage 4Lo. This is not necessary for 4Hi.

Ps. The flashing light means the shift did not occur.

You must be rolling under 5 MPH, put it into Neutral, then engage 4WD LO. Or turn the engine off, turn the key to the on position but dont start the engine, apply brake, put it in Neutral then engage 4WD LO

Some more info on a similar issue. http://www.jeepforum.com/forum/f292/...stuck-1159569/

I have found that 4Lo is best engaged while stopped in neutral. I tried the rolling at 2-3 mph as the manual says and I always get a big clunk/bang when 4lo engages. I dont get the clunk/bang when stopped and in neutral. Not sure why that is, but I use the "stopped-in-neutral" method.

Sometimes you can do it while stopped, but the reason they say to do it 2-3MPH is because when stopped the teeth on the gears may not be lined up, and rolling slowly will help the teeth line up to engage.

I've only ever used the 4lo once myself, but I did the low speed flip as well(~5kph). There was a clunk/bang for me too when it engaged.

Next time I'll try it while stopped

the owners manual states that that bang is normal, and the prefered method they say to use is the rolling method

Yup, but I just don't like it It just "feels" like I am damaging it.
