How to check auto 4wd / hi / lo range

[glenn_a]

hi there, could you please help me how to check if my HIGH / LOW range works......?

i have tried to select it on HIGH and i tried making a U turn and it seems its woking and then i fully stop and select it N position and turned the knob into LO and tried to take off but it feels the same to me....

while i was on the LO and i tried to go back to normal position (AUTO) but it kinda stuck on HIGH even sign on the 'DASH' cluster say's LO nor HIGH.
so i need to switch off the engine a re-start it again then it came back into normal mode AUTO....

first i checked; i can hear the relay clicked under dash when i change it into HIGH and into LO but when i tried to change it back to AUTO i hardly hear the relay click's....

second i checked the trasfercase motor under and i took it out and it seems it working but when i pulled it out i can turn the selector rod from N into HIGH but i cant turn it into LO, is that bad or ?

please help and tell me more what procedures i can do to make this thing work or check if its fully working properly.....

thanks!!!
