My right blinker comes on and off by itself.I hit the left blinker to stop it but then after a few minutes like that the left blinker will blink so I put it back in the middle and it stops for a while then right blinker blinks again uncontrollably.I pulled out the fuse inside truck. That's stops it from blinking outside but it does same thing in the dash even without fuse.I unplugged blinker arm and it still blinks. Hazards work normal. Please help

Have you checked the GEM Module? It is on left side behind the dash and the expeditions have a problem with windshield leaks and it leaks on it. It can cause all kind of weird things to happen light on the inside to come on when ever or the radio to do strange things and so on. So check that and let me know what you find.

I can not find a picture of it, but its a black box that is behind the dash just above the ebrake pedal. Look for signs of leakage.

I have a 2009 Ford Mustang that has a leak in the windshield on the right side and water gets in and it comes in next to my panel box with all of my fuses and every time after it rains my blinker will blink on its own for a while. How do I fix it?
