66 Chevelle brake lights flashing

I'm getting a strange problem, if I turn on my right blinker, and then while it is blinking I apply the brakes, the rear brake lights blink like hazards for about 30 seconds then turn off. While it is blinking like hazards (remember 66 has no hazards) the flasher is physically operating, you can hear and feel it, but the dash indicators are not flashing. I have had to do so repairs to the turn signal switch in the past, but this is a new problem that is not related to the previous problems. While it is blinking it does not matter what you do, you can not stop it unless you wait it out, or unplug the flasher. Any idea's ??

Sounds like bad grounds clean and check the braided ground straps from the frame to the engine as well as make sure your getting a good ground at the body/socket might need to clean off paint and make sure you have a solid ground.

Scott,

What "repairs" in the past on the turnsignal switch? Sounds like it may be time to replace the signal switch after ruling out the usual suspects (wiring, grounds, correct bulbs, flasher etc). Bear in mind both turnsignals AND brake lights control are fed thru the turnsignal switch.

Re: 66 Chevelle brake lights flashing

I tracked down the problem. Those tiny flat spring contacts in the turn signal switch. I have one that I have soldered together due to it being partially broken. The memory of the spring is gone, and it just barely touches long enough to just power to the brake lights. Time to get a new switch assembly. Does anyone know if there is an aftermarket one that uses newer technology than pins and springs? Or if just a new stock assembly is what I need to order. It is a non tilt column, Guide switch.
