Blinker feels like working when it wants to
So I've been having this weird dilemma for the past two days or so. For some reason, my blinker half the time wants to blink, and half the time wants to stay steady. About a week ago my friend and I replaced the bad blinker bulb that was destroyed in the tail light, which fixed my blinker. However, now last night I was driving normally, and my blinker was working... then when I went to go to Chilies, my blinker was a steady green. When I went out to check my car, it was blnking again.
Today, my blinker worked normally up until I got to work, then it was a steady green. Then, when I went back out to my car to go home, it worked normally up until I turned onto my street, where again it was a steady green. What could cause this?
