Switch it to 4x4 hi and the dash lights up and you can feel it engage. Switched it to 4x4 lo yesterday pulling the boat off the ramp. No light and sound/feel of the drive engaging. Any suggestions what might be going on and how to fix?

 

Check the shift motor in the transfer case and you can't be in a gear (d or r)for it to engage....
I think you need to be in nuetral with your foot on the brake.....

 

i kinda figured it out on my own by going into neutral then shifting into 4lo then park then back to drive. of course you have to be completely stopped

 

ok lemme see if that's what the problemo is.

 

same thing happened to me. Thought it wasn't working, but you have to be stopped and gear either need to be in park or neutral (cant remember which)

 

you guys were right. thanks a lot. looks like I wasn't engaging it properly.

 

lol i felt stupid because i thought i broke my 4lo but i wasn't doing it right

 

Glad it was that simple...
