Time to fix the Turn Signal

The turn signal on Ole Blue hasn't worked right since we started driving this truck 7 years ago. We can indicate the direction we are turning but regardless of direction we flip the switch it never returns back to OFF position after the turn. 

Working with my son on his 1966 Mustang he has a similar problem when he turns left, he pulled the steering wheel and found a broken return cam and found a replacement switch online so I decided to do the same.

First stop is a quick search on FTE forums to see what lessons I can take away from others efforts and bottom line is the key recommendation is NOT to try and replace the cam, just replace the whole switch. "Autoparts store replacement cams never fit or work worth a damn."

C9TZ-13341-C ...T/S Switch / Available from Ford. is what Bill the retired Ford Parts Manager says but when I looked online at our local Ford dealership they said this part has been discontinued. (Maybe since the original post from Bill was dated 2006, this has happened in the past 14 years!!). Have to find another source. 

Bill also said to follow the method the ford techs used: 

1) Cut the wires off about 1 1/2" above the connector, leaving enough so the color of each can be determined.

2) Tape the wires together, and tie a long piece of string to them.

3) Pull the switch from the column, tape the new wires together, tie the string to them.

4) Pull the string from the bottom of the column, the wires will feed down without binding up. Match the new wire colors to the cut-off pieces remaining in the connector.

"In the 1960's, there was an ancient Ford tech at the dealer I worked at, who could R&R a TSS in 10 minutes or less using this method....including R&R'ing the wheel." - Bill    

Thanks BILL!
