Question about 2003 Dodge Grand Caravan AWD
About the only thing that will cause this is the all wheel drive transfer case engagement motor has failed, to test this you will need to get under the vehicle and pull the actuator out of the all wheel drive transfer case and see if the motor works when you apply 12 volts to it, if you are not familiar with this type of testing then i strongly suggest a dealer do this testing.

This is a pretty common issue with alot of cars. It seems trying to duplicate the problem when diagnosing is hard because we usually dont have ice and a hill when we need it. If no codes are stored my first question would be what code reader did you use, A low grade one will only read PCM codes. You have several other computers in the car including the ABS traction control one.. A scanner that can access all the computers will be needed. Anything else is a guess and can get pretty expensive if one guesses wrong.
Alot of cars hav a traction control button.. When pushed will unlock the rear from the front so the car can be put on a 2 wheels Dynometer tester. Are you sure this is not the case
Most likely if you choose to have this diagnosed its possible nothing will be found.
And if they did, are you ready to fork out $1000 bucks for a maybe.
If no codes are stored a recommedation will be made to either wait or replace the computer. If it were anything else other than a computer the computer would see a issue and set a code.
