My power steering belt snapped off. Prior to that, my brake pedal was loose enough to move it up and down roughly a 1/4 of an inch with my foot. The only way to engage the cruise control was to hold the brake pedal up with my foot, then in order to keep the cruise control engaged was to keep holding the brake pedal up with my foot because it would sense that the driver slightly tapped the brake pedal to disengage it if I stopped holding it up manually. I had to have the brake pedal bolt tightened. It has happened again and I can't reach the bolt, so I have to pay to have it fixed again along with the other issues. The other issue is my a/c blend door is not operating, which is causing the two driver side a/c vents to blow warm air out of them while ever other vent blows ice cold . Not fun in these incredibly hot and humid georgia summers.
