It's supposed to do that. There's a small, very sensitive microphone in the elbow of the dirt passage coming off the back of the machine. As long as it's in contact with a dirty floor, the smallest piece of dirt going up through the hose will turn the light to red. Once all the dirt particles have been passed through, it turns back to green.
I believe you are talking about the pedal that selects powerdrive. That shaft end is stamped on in manufacturing. If you take it apart you'll see where it is to hold the shaft in place. When we see them it normally requires a used transmission. There may be a kit or something available to you to repair this from kirby but you should be fairly handy if you decide to start taking your that part of your machine apart. Good Luck!
