Last week I was driving and my rear left turn signal went out and the left signal dash light dinged and was rapidly blinking. I was going to replace the signal,but then it started working fine. I realized that when I turn left on my wheel with the left signal on it shuts the rear signal off and starts rapidly flashing. Now anytime I go to drive it is fine until I turn left and it dings and then starts rapidly flashing again, but I can sometimes make it stop rapid flashing if I turn the wheel a little. I don't want to start replacing things until I get some ideas from you guys. I am capable of using a multimeter to check any wires or parts, I just need to know what to check. Any help would be appreciated. Thank You!
