98 PA flickering headlights with clicking sound in dashboard

[tedez]

A clicking sound in the dash with flickering headlights problem appeared recently. It's intermittent. It happens with or without other electrical equipment operating such as the radio, wipers, heated seats, air/heat. When I shut the engine off the clicking sound speeds up a bit and when it stops I hear another sound like a vent closing in the dash. A few months ago I changed the battery without problems. I think it might be a module but am not sure. Could it be any other electrical problem? If it is a module, where is it located and what would the part cost?

This is strange, clicking sound after the ignition is turned off? Try this; turn off the climate control (fan) before you turn off the ignition and see if the sound is still there. Let us know what you find.
