so i have HIDs on my 94 honda civic ex coupe, but the HID on the driver's side doesn't turn on at all! I don;t know if it is a faulty ballast, faulty wiring, or a bad bulb. I wasn't the one who installed the lights. I bought my car with them installed already. they worked before. they used to turn on if i kept turning the lights on and off, but now the light wont turn on at all! any advice? should i switch the ballasts? or how do i check what's failing here?
