Brake lights not functioning and cruise con...

Lift the pedal, and see if the light goes off, if it does, there is a switch on the pedal that is out of adjustment. If it does not go off, the switch could have fallen off, or it is broken. Anyways, it is under the dash, should be right up the brake pedal. First, try to adjust it, to get it closer to the brake pedal arm, if it doesn't go off, it should be bad, take it off, and take it to the auto parts place, they should be able to test it, with a multimeter.
This is probably why the cruise control does not work also, as when you drive down the road and hit the brakes, the cruise goes off.

THE BRAKE LIGHT SWITCH ABOVE THE BRAKE PEDAL IS IN NEED OF ADJUSTMENT. SINCE THE BRAKE LIGHTS ARE ON, THIS CANCELS THE CRUISE CONTROL. FIX THE BRAKE LIGHT SWITCH AND ALL WILL GO BACK TO NORMAL. THANKS FOR USING FIX-YA. PLEASE KEEP ME POSTED. GOOD LUCK
