Great Show Scotty ...My question is about my 2005 Jeep Liberty 4x4.140000 kms...2 wheel drive is fine...4 wheel drive is fine however the part-time drive is not... the right rear wheel doesn't engage.....any ideas thanks david hart

Be happy the rest works on a 13 year old jeep. You would have to get a pro to hook up his dealer scan tool and do some testing to see what was wrong with either electronics or software to figure that one out. And that is not a cheap fix most of the time.
