Ok. My initial suspicion would be on electric parts that have a paper label on them. Heater blower motor for instance. Another possibility is any relays with paper on them. Next would be wiring with paper labeling on the wires, or wire bundle. Specifically, wiring related to headlights or blower motors (aka wires that will carry a lot of current.) 

Most of the other possibilities are going to involve burnt plastic smells (fuse box, wires, switches.)
