Why does the parking brake warning light on my 1973 Buick Centurion not turn off when car is running ?
Since yesterday, the red parking brake warning light within the instrument cluster continues glowing when the engine is running / while driving. The parking brake was fully released and the brakes seem to operate properly. Is this rather an electro-mechanical issue (e.g. sticking switch) or should I have my brake system professionally checked ?
