2000 Mazda b4000 the 4x4 light is on but it's not in 4wd

It says you answered the question but I don’t see an answer send it to madmans74j@hotmail.com if you will it clicks and the front shaft turns but it’s still in 2wd

The front 'automatic locking hubs' are not functioning properly .. Hands-on testing is required .. Recommend visiting local auto repair shop: https://repairpal.com/repair-shops
