The diverter flap inside the heater box is tough to move. The pivot rod isn't binding, its the flapper door itself. What can I do to lube this up so it will move easier?

Spray silicone should help things. Nothing is binding on a burr anywhere, is it? Is the action of the cable free?

I have the heater box out of the car and its difficult to operate it even by hand. It seems like its too big. I'm going to try and trim a little of the seal off all the way around the door. I've sanded the sides of the box smooth and put a thin coat of silicone on all of the contact surface and its still very tight.

Thanks.

Could the door just have a warp in it or has the box collapsed on itself a little bit ? Is it held in by two small pins , one on top , one on the bottom ? If so they could be rusted or bent. Just throwing out a few ideas off the top of my head. Not really speaking from experience on this one.

What appears to be happening is the rubber seal around the door want to roll over when the door reverses directions. That's why I'm going to trim the seal a little.
