Just started noticing a clicking noise while the engine is running. It is coming from in or under the dash on the drivers side near the door. It almost sounds like the blinker flashing noise, but it is faster. Nothing changes the noise, turning off the radio, the headlights or the wipers. Any idea what I can start looking for? I can't visually see anything.... Are the flasher solenoids under there? The flashers and hazards work by the way...
