2004 chevy trailblazer

today my ABS and brake light came on and stayed on. also, the air is still cold but barely blows out. it blows out stronger when driving but not at all when stopped. otherwise, the engine and all other electrical systems are all working just fine. what could be the problem

  1. 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.

    As for the Air Conditioning, do you have manual or Automatic climate control?
