Does anyone know anything about 77

Trans Am? Can't get the blower motor working. There is something wrong with the ground??? When we get a ground it only blows low.
The resister is good. Need the schmatics. Believe we have them coming now.

Finding a schematic will be the way to go there aren't many guys on here that have worked on anything that old ..
wireing on anything from the 70s tends to be pretty butched up after that many years and so many owners ..
