[tdbone1]

i have a 1999 s10 blazer 4x4 with the N1 (3 button)
the diaphram under the battery pulls the cable just fine
the 3 buttons (2hi, 4hi and 4lo) seem to work ok
they make noise when i do each one and the lights flash for a second then stay solid

4lo makes a louder noise then going to 4 hi or 2hi.

if i goto a dirt road and put the 4x4 into 4hi OR 4lo and put my brakes on and step on gas only my rear tires turn

my front dont

can someone help

thanks
