Bruce,

1. Brake sensors: there are 2 of these, 1 at the front and 1 at the rear.
Make sure both are OK. Brake light is off when there is a closed circuit, so a frayed wire will turn the light on as the circuit is now open.

2. Coolant Light. To test the sensor, short the wire (that coonects to the sensor) with a paper clip, if the light is off then the sensor is faulty (which was my case). New sensor is approx. $12.00 (OEM), dealer sells for more like $18.00.

3. Washer level light. Also check the wiring, you may want to spray some WD-40. It helped me.

Hope this helps.

My brake sensor lights are on-the sensors themselves were replaced,and the pads and rotors are all new. How do I get the stupid light to go out? I also have the washer fluid light on and the coolant light on but there is no problem....short of pulling out the bulbs where do I go from here? Thanks
