Hi, first time post so I wonder if anyone can help. For the last two consecutive Saturdays I have parked opposite a friends house and returned to my Mazda 6 to find all four windows opened. The first time all were open by about 3 to 4 inches and today all four were fully opened. I didn't think the electric windows could be opened without the car 's ignition being switched on. I know there is a slight delay after switching off giving time to fully close the windows but I have never encountered all four windows being opened remotely before. Has anyone encountered a similar situation or know about the problem that I have. Thanks in advance for any help.
