I also just bought a bronco, 1991 full size, with the same two switches and they worked for the first week, then I went hill climbing and found myself stuck in some sand. I figured out that the windshield wiper motor on the transfer case was sticking and had my wife continuosly push the 4x4 button as I tapped on this motor and it engaged, I then put the bronco in nuetral and pushed the low range button and it also engaged. I have not found a permanent fix for this but I will soon convert my bronco to manual lock out and advise you to do the same. The conversion kits are not very expensive and you can research the how to online. >I just recently acquired a 1990 Ford Bronco II with a
