From here, it's all diagnostics. Is your trans working? Is the shift motor on the transfer case getting power? Is the trans full of fluid? When the 4x4 light is on can you manually turn the driveshaft in front?
 
When i turn the switch to 4hi it locks but still nothing but wont go into 4 low trans fluid is full and clean doesnt smell burnt or anything
