4 wheel drive problem on a 99
 

Ok having a problem with my 4 wheel drive.

I have the electronic 4 wheel drive not the stick. When i press the button for 4-hi or 4-lo i can hear it engage and i can feel the added torque. But the front wheels dont turn. Also the light next to the 4-hi/4-lo buttons continues to blink instead of going solid as they should.

If anyone has any advice for me regarding this issue please let me know,
Thnx
