Need advise po fellow tsikoteers..

I often use my lynx's defogger and just last week, I noticed that two copper lines were not functioning as evidenced by the their inability to remove the moist.... magkatabi lang po yung dalawang coper lines na yan kaya isang block ang hindi natatanggalan ng mist. My suspicion is that there might have been a short somewhere..as a result, natuklap yung portion na yon ng nilagay na tint..maayos pa ba yon (defogger)..thanks..I already read something about damaged defoggers pero yung case namana na yon eh natangal yung ends at di na ata puwede i solder..
