Electrical: Turn Signals Dim

[GTCruiser]

All four turn signals are dim on '65 Cruiser. Brake lights are bright. Just replaced brake light switch. Turn signals were dim before replacing the brake light switch. Is/are there specific grounding point(s) to check for the turn signals? Or any other advice? Thanks

The rear turn signals use the same filament in the same bulb as the brake lights. When BOTH a turn signal AND the brakes are on, the brake light on the side with the flashing turn signal needs to be turned off. In order to do this, there is a relatively complicated switch at the turn signal lever under the steering wheel. My guess is the contacts in this switch are dirty.

It is a PITA to remove and replace.

Could a guy get some tuner cleaner from Radio Shack and work the red straw in to turn signal switch without removing it?

Yes you could try that but not without removing the Steering Wheel.

Getting to the contacts is pretty straight forward once you ge the wheel off. You have to be careful when prying off the turn signal canceller. From bad experience I will caution you to not spring or distort the little copper contacts in any way while cleaning them or you will never get them back to their original position to work properly. I did it and ended up buying another complete switch.

The switch is turning off the brake light on the side when the turn signal is on. Have replaced turn signal switches in other Studes and the turn/brake light wiring assembly. As recommended, will get some of the cleaner and remove and clean the turn signal assembly. Thanks
