The heater box, cables, and heater control are all out of the car. What kind of lubrication should I put on the cables before re-installing everything? I have dry lube, silicone spray, oils, and white lithium grease. What is the best choice?
I have a liquid lubrication for my bicycle chain that is waxy. It dries and leaves lub in the chain that won't attract dust and dirt. That might be a good choice.

No Lube

use Graphite
Lube will collect dust .. and you will be taken them out again..

hope that helps

Graphite - that just might be a good idea. Thanks for responding.
