Check blower fan fuse with a multimeter or inspect it for an open.
Scan for DTC codes.

A parts store will scan for free but their scanner may not read the HVAC module.

Which radio is in your truck?
A picture would be helpful if you don't have the part number.

What is the history and why were all these parts changed?

What diagnostics were performed?
