Piper Cheyenne II AOA Issues

We have a 1981 Piper Cheyenne II (Ambulance) and are having some issues with the Angle of Attack indicator(AOA) Model 861 Cd2, pt no 29316-02.
The issue I am having is that the vane that goes outside does not want to heat up. It seems that the heating element is not working. The body does heat up ok.
I am having difficulties finding an exchange unit or an OH shop.
Any one has any clues?
Thanks
