I have 2 questions, first one my service light is on but goes off when I drive it after about 10 minutes, How do I turn it off? Secound question, my heater / AC is acting up. It is a electrontic climate control, when on AUTO it has to be set as low as it can go for the AC and as high as it goes 90 for the heater. This same problem happens on MANUAL setting also. What is the problem with it?
