2005 Red Roadster - 40k miles

I brought my car to a local service station as the wiper was not working. They replaced the wiper motor for 425.00 and when the wiper still did not work they stated that the vehicle may need a new body control module.

Everything else in the car works perfectly. Anyone experience this or have suggestions?

On the bright side the dealer is replacing my entire convertible roof under warranty because of the glass coming undone
