As removed, reported to be working when purchased to resell. PPG part number 33323. Known to work on 14-volt Aztec and Seneca's (possibly others as well), please verify before purchase. Not sure if a separate heating element is needed, and plugs were not marked positive or negative, so not tested since in my possession. Can be returned within 30 days if not satisfied.

*This item is guaranteed to be fully functional when received, but airworthiness is a separate matter determined only by the certified technician performing installation or certified repair station and is the responsibility of the buyer.*
