Thanks...your response is appreciated! When I bought it, all I did was drive it across the parking lot over to my trailer. When I got it home after a few miles I noticed it would not shift into 4W & none of the rocker switch's were lite up. Come to find out it had blown fuse, replaced the fuse....but it has acted funny ever since I brought it home..not good. Also realized my dealer is closed today which is 2.5 hours away. Anyway is there away I can pull the codes? Thanks again!
