Stickler,

If it attaches to the firewall, it might be a recirculating heater similar to the one in these instructions.

A variety of GM and non-GM heaters were available. If you can post a few photos, someone will be able to confirm exactly what you have (and how it is installed).

After-market 6v heater motor switches and 12v heater motor switches are available from most parts vendor.
