Re: 71 blazer heater/defrost box
Whatever you have there apparently did not come with that truck because I can see the mounting holes where the original box was mounted. Are there provisions for a heater core inside the box, or any sign of openings that heater hose could have been routed into? Otherwise that box is pretty much worthless as a defrost without a fan, and worthless as a heater without a fan and source of heat.
