If you are now having trouble with braking such as the pedal going to the floor, then you most likely have a brake fluid leak. If the brakes are still stopping OK then the most likely reason the lights are on would be from a failed speed sensor. The speed sensors are located internally in the hub bearings. Hub bearings are a common failure part on this vehicle. The bearing goes bad and takes out the sensor in the process.
How to replace a Hub Bearing
As for the Air Conditioning, do you have manual or Automatic climate control?
