4x4 reset
I have a 95 Blazer 4x4 (stock) and I have to keep reseting the computer to get the 4x4 hi to work. 4 lo still works fine by putting it in nuetral and hitting the switch then shifting into drive. I can then shift it from lo to hi in the same manner once in lo range. If Im in drive and try to use on demand it just blinks and goes back to 2wd. This is a three button switch.
Any ideas?

IMHO The 95 still uses the same shift motor/solenoid the 94 did. But the control is integrated into the ECU instead of being a separate control box.
The reason on the 94's to shift only between 2HI and 4LO is the encoder switch. On the 94 it allows for a couple of switchings before it has accumulated enough faults to go into a kind of "limp" transfer case mode. Then it will allow only the shifting from 2HI to 4LO. I guess that the 95 may be the same.
Just a thought.
I would start looking into the reason for the erratic shifting, rather than just to reset.
