I put my truck into 4 wheel drive. The 4x4 transmition ingages okay. However, the 4x4 light on the dash dosent come on and, the 4 wheel drive dosent work. It stays in 2 wheel drive. The light on the dash dosent come on in 4 wheel low ether. All the vacume lines seam to be in good shape. I replaced the 4 wheel actuator switch with a new one, still not going into 4 wheel drive. What to do next?
Check for vacuum at actuator. Then check if vacuum switches direction when you move 4 wheel selector.
Where is the 4x4 actuated on a 99 dodge Durango 5.9

Vacuum switch is on drivers side on top of transfer with four vacuums on it the actuator is on front passenger side of drive axle
