You have a bad short--I'm not trying to be funny but do anything but keep that thing!!! I had a truck that the heater would come on and the left blinker would go on and off. Not all the time but just when it wanted to. I had 6 places look at it and no way could they even tell me why. $$$$$$$$$ There was no way I could find the problem, Funny thing I went to the city and someone had stolen it, my poor broken heart!
