I have a 2007 Ford Mustang. The other day, I was driving and noticed that when I pressed down on the brakes, my door ajar light would start to flash intermittently, sort of on and off with no pattern. When I take my foot off the brakes and press the accelerator, it stops. It seems to gets even crazier if I have the turn signal on. I checked all of the doors and the trunk...none of them were open and the latches looked clean. I did notice today that the passenger side window didn't roll back up when I closed the door, but that fixed itself after I used the button in the car to roll it back up. I'm thinking I might just need to put some WD-40 on the latches, but wanted to get a few second opinions. Thanks.
