Hey guys.

Does anyone know of anywhere that sells this? I’m trying to figure out why my heater isn’t coming on on my 86 c10 and for some reason mine control box has this style of set up on it instead of the 84-86 version I’m not 100% if that’s the problem or not on why my blower motor isn’t kicking on but i changed everything beside the fan speed switch and that piece behind the climate control box
