Buying an 03 h2....Need help with the 4x4.

[love dodge]

I did a little search before getting into this stuff...I know(after fighting with the owner) that the top one 4hi is the one for all the time.And the two others are the locking ones 4hi and 4lo..And the round one should be used only with the 4lo on mud,snow situations...But it looks like the truck is in 4lo all the time tho...And the light is on on the 4hi ( the one for everyday use).If i switch between the buttons they work fine and u can hear the 4lo engaging..
So in other words this is NOT NORMAL right?
Something is wrong them...I going to reset the thing tomorrow e see what's up..Damm i liked that h2 man....
