I am stumped. My explorer has me running in circles. Left directional is operating fine. If I push the turn signal upward, to signal right turn my relay starts to buzz. (The yellow one under the driver dash). If ?? I just push the lever without it clicking and let it blink a few times then pushing it into the click position it is fine and does not buzz. I have replaced the relay, I have replaced the turn signal arm. All light function correctly. Anyone have any ideas. John
