To the right of the speaker, inside the passenger door of my 2003 Element was a circuit board about 2"x1" with a large yellow capacitor, coiled wire transformer?, and a white resistor. 2 black and 2 grey wires were soldered to one end and 1 black and 1 grey wires were on the other end. This morning, driving along, it caught fire. I'd like to know what that part is called and why it would catch on fire. The window and radio still work -- not sure about the speaker in that door.
