most likely the 4wd switch module or the 4wd motor is bad not switching

we need a Chrysler scanner or equivalent & retrieved fault codes from the 4wd module

we can try resetting it for now .

Master reset Procedure

1- Disconnect Battery Cables ( Negative & Positive Cables )

2- Hold cables Together for 60 secs ,then let go

3- Wait 15 minutes

4- Make sure all doors are closed

5- Reconnect battery Cables

6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)

7- Enter the vehicle and attempt to start

Please let me know , if that reset it or not .

Thank You
