4wd lo not working

[RumpRanger98]

So I was driving around today and was about on my way home from my last stop, and the 4wd lights flashed 6 times. I got home, I pulled all the fuses and put back, did not change anything, also pulled all relays and put back, no changes. I started the truck up and the 4wd stopped flashing. So I figured maybe something was lose and i fixed it by messing with the relays/fuses. So I put it in 4wd hi, 4wd hi on dash lit up and i could hear it shift. I put clutch in and tried 4wd lo, but no change.

any help please? Im new to 4x4. I haven't actually even used it since I had the truck but I know it was working properly when i bought it. thanks

I figured out why it wasnt going into 4wd lo, suppose to hold the brake down and clutch in.
