My mother's 2004 Durango had the check engine light come on a few days ago. I was wondering if there is any way to get the diagnostic code to see what caused it to come on without having an OBD II scanner. In my 06 Charger, I can get coeds by turning they key between Acc & On 3 times to display the codes in the odometer window. Is there a way to display codes in the Durango?

 

Did you try the key technique on the Durango? Some of the national brand autostores will read codes free of charge.
