This is a problem that you will need to diagnose with a good scanner. Do you have someone with Star Diagnostic or iCarsoft MB II?

See if your scanner lets you activate the wipers. Also check the operation of the switch on the wiper columns. It has been a long time sine I last used Delphi scanner and I can't rember if it allows you perform those tests.

Let us know what you or the dealer find out.

dealer replaced SAM module (front) . who knows if that was really the problem.that was on the bill. high doubts that was really the part that cause wipers not working.
probably relay that cost 25.00...
