Today our Saturn Wagon started acting strange...when the car is turned off and we push the brake, the lights come on and chimes ring? Also, cruise control stopped working later in the day...
First thing I would have done is to hire someone to perform a seyonce on your car to rid it of the spirits within. lol
Next, I would look for a possible short, in a loose set of wires under the dash around your feet. The chime is probably ringing, not because of the initial problem, but because the lights are on with the key out.
Lights & chimes when brake pushed??
