  1. Im a proud owner of 2003 Lincoln LS. I’ve run into a problem with the dealer when the sun roof seal failed and water ran down inside the drivers metal arm that connects the roof to the body of the car. The dealer fixed the leak, but the next day the remote entry and starter was not working,the dealer said that the water must have entered and shorted something in the module that is located there.They said they could not find a replacement in Ontario or Quebec and then refused to help me any more. As the unit dried my remote will work only when pointed within 3 feet of the driver side arm and at times much farther depending on the temperature and humidity outside.
    Can a module be cleaned to restore it’s original working distance? Is the part inside the arm at all? I’ve been told there is nothing in there. Thanks, Rob.
