Ok this is the problem 2011 T&C. I start the car the blinker works fine for about 10 seconds. There is a beep and then it gos out and blinks fast only on drivers side. Bulbs are fine as is the wiring harness. no corrosion any place. just started. Thought it might be the battery so I got i changed today with no change. If i turn the car of and on blinker works fine for 10 to 15 seconds then fast again. Weirdest thing i ever saw. what you think it is.?
