I tried to put the truck in 4 wheel drive I hear a clicking sound coming from the dash board

Hello,

It sounds like an issue with the transfer case module. That module is located under the passenger side dash.
Clicking noise tells you that the module is getting power but unable to change setting.
This could be also due to the module not getting proper power. This can also make the module not to function.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
