Major light problem - MOT failure - any ideas?

[johnd]

Hi,<br><br>My brake lights are constantly on when electrics on and also driving. Pressing the brake pedal even when switched off activates the computer/prevents engine shutdown on occasions. Any ideas?<br><br>Thanks<br><br>John <p></p><i></i>

It sounds like an earthing problem somewhere, I would check the rear light connectors first to check for corrosion on contacts etc. <br><br>Another possibility is that the microswitch on the brake pedal is out of adjustment and not cutting power to the lights. You may be able to quickly test this by lifting the pedal to see if the lights go out. This wouldn't explain the prob with the info centre though. <p></p><i></i>

Even if your brake light switch were knackered and your lights were coming on/off at will even without the ignition, it should not cause the other problem so go with David's first suggestion. <p></p><i></i>
