Tim,
My panel is a Chev and the heater is GMC. No telling what year the heater
was made. Fan motors honk right along with 12V negative ground. And the
air flow moves in the right direction.

Hope someone in the electrical forum can help me determine if the motors
are 6 or 12V.
Thanks fur yer hep'
Jerry
