DETROIT - General Motors Co has been searching for a new chief financial officer and may have a replacement for CFO Ray Young within weeks, GM's Chairman and acting Chief Executive Ed Whitacre said on Tuesday.

We're close and have narrowed it down and have a real good candidate, Whitacre told reporters in a Web chat, adding that GM could have some news in two or three weeks.

Whitacre's response was the first time the automaker had acknowledged it was looking for a new CFO. Young's departure would mean that GM had replaced the three top executives who were leading the automaker a year ago.

Rick Wagoner was ousted by the Obama administration as chairman and CEO in March and his successor as CEO, Fritz Henderson, left GM a week ago following a disagreement with the new board. (Reporting by Kevin Krolicki and Bernie Woodall; editing by Gunna Dickson)
