Turn Signal Problems

The turn signal in my 1969 F100 went haywire last night.
I could turn it off. If I put it left, only the left blinked, but I couldn't get it to stop when I put it in neutral. If I signaled right, both signal lights went on. It was looking like "emergency lights," even though I don't have any.
Coming home today, the signals went back to working. ????
(I did put in a new "flasher.")
What should I do now? Any help would be greatly appreciated.
Thanks, Dan.

If it comes back I would replace the turn signal switch. Check for brake lights as well. Your brake lights are routed through the turn signal switch.

There were two different T/S switches used in 1969.

C9TZ-13341-C (replaced C5TZ-13341-A) .. T/S Switch / Available from Ford.

MSRP: $61.98 // FTE sponsor partsguyed.com (Horizon Ford in Tukwila [Seattle] WA) price: $44.63.

Applications: 1965/66 F100/250 2WD / 1966 F100 4WD / 1967/68 F100/350 / 1969 F100/350 before serial number G30,001.
-----------------------------------------------------------------------------------------------------------------------
DOTZ-13341-B .. T/S Switch / Obsolete / 233 available NOS from Ford Dealers/obsolete parts vendors.

Applications: 1969 F100/350 from serial number G30,001 / 1970/72 F100/350.

The serial number is the late 6 digits of the VIN

NOTE: There are two flashers on these trucks, one for the turn signals, another for the 4 way emergency flashers.

They look the same, but the 4 way flasher is a H/D unit, has a louder click. The T/S flasher is mounted behind the instrument cluster.

The 4 way flasher nestles into a bracket that is retained to the dash with one screw. Located adjacent to the radio.

The emergency flasher can be used for the turn signals (and was with trailer tow, peeps that were hard of hearing), but the turn signal flasher is not a H/D unit, should not be used for the emergency flashers.
