I think I should’ve been more clear in my first post…. Yours looks like a heater cable, yes. I need a “fresh air vent” control cable with the push/pull handleIt's the shortest one I have. This was from a 76 D-100. I'm not sure what heater door it operated but it works smoothly & I will send it to you for $23 shipped.
No worries, appreciate your timeOh, I understand now. Sorry, it's all I have.
