If the hazard lights are turned on, only the rear-passenger light blinks. (nothing blinking in front) If signalling a right turn, the rear-passenger light only blinks rapidly. If signalling a left turn, no lights blink. Signalling either left or right turn, the turn signal indicator on the dash blinks rapidly. Checked the bulb in the rear-drivers side and it looks okay. Not sure where to start diagnosing this. Any help appreciated. ---
