I was traveling on the beach today and got a little stuck. It was no problem, I just put it into four wheel drive and drove out. When i got done and put it back into two wheel drive, the O/D OFF light on the dash started blinking and it hasn't stopped since. The overdrive button works fine because i tested it on the highway back home, but the light won't stop blinking. I even stopped and re-started the car over again to see if it would go off, it didn't. If someone has had this problem, please let me know what it is and how it can be fixed. Thanks.
