Sorry my bad. It was 2004 H2 with 140k miles on the clock. Offroading in the dry sand dunes. I did crawl underneath and check the connection,seems to look ok but I will attemp with your suggestion this evening. 2 days back the actuator did responding but only half a click whenever i'd try to select 4AWD whilst compare to the 4low or 4high it produce a full click sound. I am assuming actuator gear might loosen or broken.

Clicking as u push buttons
 

Update.

T-cast shifter click only between 4HI to 4LOW but won't click on 4AWD. I decided to remove the actuator and tried to manual release it by turning counter clockwise the shifter shaft on the T-Case in attempt to release it back to 4AWD but unable to shift it back to 4AWD offcourse with the gear in Neutral. What actually wrong here,The actuator motor or T-Case?
Whenever I try to unlocked it manually I felt a resistance. It was free move for a half turn at first and then it felt like there is a spring attached. I couldn't get full turn due to the resistance. Is that normal?
And also, 04 H2 T-Case actuator motor is identical with 04 FORD F150 isn'n it? By the look of it triangle shaft shape,it look identical.
Any help is appreciated

Update.
I removed the actuator and try to shift it just to see the respond of the actuator itself. Guess what,it moved corresponding to the gear selection. Now I'm puzzled,does this mean I have a bad Transfer Case since the actuator motor is working fine? If so,what is the recomended?

Hello Reynold,

any update on your issue?

Cheers
