I am sure ther are but I cannot find reference to them in my information. Try getting a garden hose and see where the water drains under the car perhaps only one side is plugged or restricted. Drain tubes for sunroofs usually exit under the car at the seem that the jack is attached to raise the car, perhaps the seem has been pinched shut due to previous body work also look for and drain tubes under the car toward the rear, try poking a close hanger in the ofice and see if it dislodges any debris.
