I got my 2008 ram stuck in 2wd. Switched to 4low, eventually got out but now I can't switch to 4 hi or 2 Wd. If I switch to 4 hi, 4wd just blinks. If I try to go 2wd then the 4 low just blinks. And it says ESPoff on the dash. Any help?

 

I assume it switch on the dash? Check the vacuum line going to the front differential. That system is vacuum operated. Did you try the switch in neutral and park?
