Air Conditioning problem
2003 Toyota Camry 4 cyl Front Wheel Drive Automatic 60000 miles
My AC light has been blinking and found that I need to replace AC magnetic clutch relay. I bought the replacement part online and I am ready to do it by myself. However, I would like to know if I need to disconnect the negative terminal of the battery before I do the replacement or it will not harm the car electrical system if I don't disconnect.
