My 66' hardtop will only pulse the 2 rear outer lamps on both turn signal directions. No center lamps. All brake lights work. The front fender indicator lamps come on solid on both sides. However no life from both parking turn lamps. Verified both parking/turn lamps good. I have read that both front lamps flash in conjuction with rear center lamps. Also froont fender turn idicator lamps will remain on solid with buldb issue, Have removed and cleaned the contacts on motor pack and turn signal relay in rear trunk pack.
ANYONE have any ideas on why my rear center lamps and the front tun signal lamps won't work??? should note my flashers are not working either.
Thanks, Greg.

Went over my motor contacts once again and found the center contact still needed a better cleaning as it was pitted. tested thoroughly then installed in car. All my turn signal lamps rear and front are working!!! The only minor issue the right fender indicator lamp stays on solid vs blinking.

Why not contact John Draxler at the Thunderbird Ranch. I know he has worked on these often and has replacement parts if needed (or an electronic unit if wanted). Check his website at 'tbirdranch.com'

Try starting the car and see if the right indicator lamp blinks when the car is running. I have that problem with mine when the lights are on and I am idling at a light. You might try cleaning the connections on the current sensing relay. It is mounted under the dash on the drivers side. You can hear it clicking when the indicator light is blinking. It sounds like a flasher. Good luck.
