I just found out my brake lights are malfunctioning. All three lights wont go on until I push hard on the brakes. The guys who changed my oil think its anelectrical short since all three back lights are not working. Could it be the Brake Light Switch or a full blown short? I'd also like to mention the fact that the lights on the radio don't work but the lights on my computer council and heat/air do. Can anyone help solve this dilema? Any help is greatly appreciated.
