Blinking switch lights
Here's a strange one. Lately, when my foot is on the brake, car in any gear but Park, the lights inside most (but not all) of the interior switches (e.g., window switches) start to blink on and off. This despite the fact that the headlight switch is OFF so those little light bulbs should not be getting any power. Obviously there's a short somewhere, sending power into the lighting circuit. Any ideas where to start? The fact it only happens in gear and with the brake on makes me suspicious about the brake/shifter interlock, though I believe M.B.Doc said this is a purely mechanical interlock.
Any thoughts would be appreciated!
