Looking for more help with transfer case problems for Discovery II SE. Front Driveshaft has been removed and I am trying to use rear drive only. I moved the CDL lock 1/4 turn clockwise on top of transfer case as has been suggested but to no avail. I do have Two (2) blinking lights bottom of cluster "M" and "S". I can not get transfer lever out of 2 High with park Brake and Brake Pedal down while in neutral. When I put transmission lever in Park its as if it wants to engage but does not , sort of a light grind. Any thoughts and suggestions will be most helpful.
