So today I changed out my dash lights as they were all burned out. I put everything back together and check my 4x4 to make sure it still worked. I switched it from 2-4hi-4lo no problem and then tried to switch it back and the lights went off but then started flashing when i turned the vehicle back on and now i am stuck in 4lo. Prior to this everything worked flawlessly. Bad shift motor? They flash 6 times if that means anything. Any help would be great as i cant drive my truck to work bc of this.
