I have a 2001 Jeep Grand Cherokee Laredo 4.0L Selec Trac

When I engage Part-time, the orange "part-time" light in the dash comes on, and 4x4 works.

When I engage Full-time, No light comes on, but 4x4 works.

When I engage 4 Lo, the orange "part-time" light comes on & 4x4, and Lo work.

Question: Is there a "full-time" light in the dash on the 2001 model?
