"Part time" light flickering at idle while in 2WD

[SteveMann]

I noticed the "part time" light flickering while at a light recently- should I worry?
(2003 Grand Cherokee, 150K miles).
I rarely use 4WD- only in the winter when our roads don't get plowed until late morning.

I am not a DIY mechanic any longer, but I hesitate to take something simple to the dealer.

Advice?

first I would look at position sensor and its wiring.

Thanks. Come to think of it I did drive over some really rough roads under construction recently....

So, absent any other symptoms, you wouldn't think it's an urgent, 'must-repair now' item?

absent of other symptoms - back burners ok
