Hi, I am a owner of a new to me 2010 Mazda 5 GS. I am having some difficulty with the rain sensing wipers. I think that the plug for the sensor may be loose, reason being is that the wipers were not working on auto then I tapped the sensor cover lightly and they started working. Does anyone know how to remove the cover for this sensor(lillte black box in front of the rearview mirror)? Any help would be great I just dont want to force it if there is a trick to the removal. thanks
