Pops into 4 wheel drive when 2 wheel drive is selected
I have a 2001 Durango and for over a year it has been popping into four wheel drive when the selector is on two wheel drive. You can move the selector knob all you want and it will not go out of four wheel. Sometimes if you turn the car off and restart it it will change but it soon goes right back to four wheel expecially if you slow down or break. So far the dealer has had it in the shop 5 times and they can't figure it out. They have replaced the modulator, the computer chip, etc. to no avail. Any ideas?

if the car is all wheel drive you will have to engage center diff lock
if ordinary 4 wheel drive there will be no problem because if you have it in 2 wheel drive high it is the same thing as having no front drive shaft installed
Four wheel drive vehicles with inside the vehicle four wheel select buttons etc. have plug in four wheel drive control modules, you need to find where yours is located some are under the dash, behind the glove department. others are under the battery box..it can be a DIY job. they are somewhat expensive $ 200 or so..and come in so many modeks..you need to find the exact number of your modual even though you give your vehicle model they vary greatly due to vehicle options...without it your four wheel will not engage....garage cost will be approx $ 400++ so try and find it..Good luck..
sounds like the front wheel lockouts are not engaging properlyor the front driveline u-joints are going bad...driveline work is not cheap but i would definitely take to a garage and get it looked at with an estimate
My GMC Jimmy '01 would slip from 2-wheel to 4-wheel drive while I was driving. First time it happened my mechanic replaced a small part. This last time, he couldn't find anything wrong so he popped the 2-4 out and disconnected the 4-wheel drive. Now I don't have the problem.
