Spraying your sensors with lube won't do anything. I suspect he meant 3 actuators, which power the flaps for hot and cold air, direction and demisting. The lube inside these often dry out, leaving them prone to incorrect working conditions. Try this YouTube link, as it tells you where they are and how to fix them.
