Narrative:

Abnormal odor while approaching destination; initially identical to peanut butter; then dull electrical. I mentioned windshield and side window heat issue(s) based on past experience. We immediately suited up and communicated. We looked everywhere for smoke and only first officer could see slight stream (like a single blown out pastry candle) emitting from the electrical terminal bar at the top of the right windshield. I immediately turned off the windshield heat and the odor and slight smoke stream ended immediately. We reviewed the smoke related checklist(s) and continued our descent and landing without further incident. Upon speaking with maintenance control we discovered the same thing had happened on [a previous date].
