"Anyone who wants the details, post and let me know, and I'll post them here."

Now this is frustrating...

Something is up with my A/C wheel. It almost wants to go past "Max" to fully engage, and will do so if I hold the dial there with my fingers.

*Edit: here's the solution.

Remove the wheel, take it apart (easy and obvious) and clean the corrosion. Replace the grain bulb while you're at it.
Done.
