No brake lights/turn/hazard

When any of these are used, nothing happens, like im not hitting the switches. Fuses checked out to be good. Bulbs are good.

Any Ideas? I just got the car running, and I'm messing with the wiring under the hood. Gauges all work, and it charges, im just weeding out the ECU, with out cutting wires, or so far atleast.

The one place that all those circuits converge is the turn/hazard signal switch.

Is is possible that the switch went bad as the car sat for almost 2 years?

"Bad" is a relative term. Try exercising the switch a bit, especially the hazard flasher function. I've had them get "strange" after long periods of no use, and a little switching can clean/wipe the contacts enough to restore operation. It's worth a try.

Thanks.

When I droped the motor in I forgot to run a ground to from the block to the firewall, so I ran one to where all of the wires converge on the firewall. Got in the car, and fliped the switch both directions a couple of times and the blinkers worked. Double checked the hazards and the brake lights, and still no power.

So I crawled under the dash and pulled the fuse in that spot, tossed it and replaced it and everything worked.
