Ok...all ready to sell car, but have a few final things to sort out first. A.) The steering makes a thunk at about twenty degrees off center in either direction at low speeds...why? 2.) Where are the turn flasher relays located? 3.) What kind of light bulbs go into the front turn signals? I have a pack that the guy gave me with the car; they look the same inside and out and they light up, but they make the signals act wierd....they won't blink with the lights on....why?
