Help! Last year I took my '06 Civic to the dealer because the wipers didn't work correctly in cold weather...it was February 08 when I went.

Now, a year later the problem has resurfaced. I went back to the dealer and they want to charge me $100 to diagnose since I'm out of warranty. I feel they should fix it at no charge...the problem only occurs in cold weather. Maybe after the fix last year I didn't know it wasn't done properly because it didnt' get cold enough??

The service bulletin indicates if the car is out of warranty they can extend some kind of courtesy and repair it but this dealer won't do that.
