The brake switch wasn't sending the signal down to the torque converter. So I tried two new switches. First one from Oreilly's (BWD) for $13. I played with the plunger about 10 times, worked fine, then it quit sending the signal. Couldn't hear the TCC solenoid and checked for 12 volts. Nada. So then I went to Advance and bought the cheaper one for $7.99. Pressed the plunger in, worked fine for 3 plunges, then nada. I checked for 12 volts right on the switch. Nothing. Brake lights continue to work so I know the switch is getting power. Anybody else have this issue? Just ordered two GM switches from Rock Auto for $14 each. I hope I have better luck.
