Brake lights only work sometimes. All the bulbs are good. Removed the brake light switch and it tests out good. The fuse has never blown. The tach and the cruise and the exterior lamp failure monitoring unit are all on the same fuse. Right now the brake lights do not work. Don't know what to check next.

When this happens have you checked voltage trace thru switch to bulb and bulb ground? These cars are known for grounding problems.
