    Hello,I have received some relay/fuse panel diagrams for my car. . There is a 10 amp fuse for brake lights which looks good,but I will replace. Next, there is a stop lamp inhibit relay(which is energized when brake light switch is activated by foot pedal). I have already replaced this relay-brake lights including center lamp still dont illuminate. It may be then, that changing the brake light switch under foot pedal- is the best next thing to change. What do you think? Thank you in advance!

    Rather replacing every next item that comes to mind, why not diagnose the fault.
    Do you have a digital multi-meter (DMM)?

    why would any viehicle use a brake lamp inhibit relay? what possable use would there be for defeating the brake light?

    have you tried simply pushing the switch with your finger? ive had two vehicles so far, in which, the switch assy itself had slipped back and was no longer close enough for the pedal to activate. a mechanical adjustment of some nuts on the threads had everything back in working order very soon.

    It is used with ABS Module,it only inhibits the lights in certain circumstances. If it malfunctions it can keep the lights from working all the time.Thats what I have read on forums.

    Turn signals come to mind.

    All the lights work front and rear-except both brake lights and center lamp

    why wouldnt you want to warn people behind you that you are slowing for a turn? or stopping with your turn signals on? no brake lights means a ticket at the least, a rear end colision aolso.

    I'm with alfacliff. In my experience, there is NO WAY to inhibit a brake light signal. I demand extraordinary proof of the extraordinary claim that there is any way to prevent the brake lights from coming on when the pedal is pushed, except of course for the unintended fault the OP is dealing with.

    What engineer would risk his career by implementing such a thing?
