Thank you very much. I have an inexpensive multimeter at home, and a
really fancy $2K model at work. I'll use them to check out the
circuits.

As to the location of the switch. A light bulb just came on in my head.

The car was serviced in December by a local garage because the brake
pedal was set too low, and they "fixed" it. Grrrrr...

I guess they did something so that the switch no longer functions.
Ofcourse, no one noticed except the cop that pulled me over.

Thanks again.
