1999 Volkswagon Jetta you tried to start the car the headlights radio dash lights work like normal but when you turn the key to start there is a clicking noise and it won't start please help repetitiv?

clicking noise is the international sound of a discharge battery. just because the lights and radio works it don't mean that the battery has the amps to turn(crank) engine. a faulty "holding winding" on the starter solenoid may also show as that symptom.also check the neutral safety switch. try a headlight start test. turn on your head lights and crank your engine have someone look at the headlights while you crank if the headlights dim it would be a good indication of a discharge battery and or high resistance on the starting circuit. if no difference on the headlights the problem may be an open circuit.(most likely a bad ground)
