2002 Mazda B4000 Q&A
2002 Mazda B4000 Question: will not switch to 4 wheel drive
This is an electronically controlled system, the selector switch controls the 4WD module which commands the transfer case operation. Fuse 9, 7.5A, in the Central Junction Box powers the brake lights and 4WD control module. Check that the brake lights work. If that fuse has blown, the 4WD won't work. It's possible that the switch has failed but there is more to the system. You may need to see a Ford or Mazda specialist or an auto electric shop to diagnose and estimate this problem.

when I flip the switch to four wheel drive the indicator lights on the dash light up but the truck does not actually engage.
I'm not quite sure what the difference is between "low range" and "4x4" mode in my mazda b4000. I'm not even quite sure how to turn the two on because I have to push the button and then go into rev...
When I flip the switch for 4wd the light comes on but 4wd will not engage what is wrong
