I've been trying to fix my brake warning light switch, it flashes all the time. Occasionally I could get it to go out by slamming the P-brake all the way down, but it would eventually turn back on again. So I figured it was the switch under the P-brake handle. I pulled the switch out and it doesn't seem to do anything, but it looks fine to me?? The wire that leads to it looks okay too.. Is there a way to test the switch?
I was thinking it could be the m/c reset button, but doesn't make sense if I could get it to turn off with the P-brake before.. |

The wire probably meets up with the wire harness in the center tunnel.
Disconnect the wire at the bulb & switch and remeasure the continuity from both ends to ground (you should have an open circuit, infinite resistance) and end to end (closed circuit, low resistance like 1 Ohm). You could be grounding at the bulb/socket/gauge |
