If someone has heater/fan issues, and has batt voltage at the green/black wire at each of the relays on the heater housing (key ON), then your problem might be the resistor wire is broken in two or burnt up.

The resistor is found on the bottom of the fan housing. Held with two phillips screws and is oval in shape. Pull it out and you should find a spring like the one in the attached jpg. If one or the other end of that spring is broken, then solder it back in place.
