Q: will not switch to 4 wheel drive on 2002 Mazda B4000

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
When I use the selector switch, it will not go into 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.
