Wiper Blades just stopped working

Resolved Question:

I was driving in torrential rain tonight on expressway and my wipers just stopped in up position (very dangerous). I drive 2007 Chevy Impala. I will be taking my car in to be fixed tomorrow morning. the fuses were fine. Would you suggest this is more likely to be a Wiper Motor or Wiper Transmission issue?

I have read articles - is there any recall to this issue? What time (labor) and potential cost would I expect to make this repair

If this does not work, replace your wiper module. There were many problems with these in the past and is most likely the problem here. The module sits on top of the wiper motor and takes about 5 minutes to replace.
