Where is the brake light switch in a Picasso?

Answer 1

It is located at the very top end of the brake pedal. This is a common fault when the brake lights stop working, it is usually the microswitch sticking. If you run your hand from the footpad up the fronty of the brake pedal metal arm to the very top, up behind the lower dash area bit, you will find a small plastic box with a button protruding. The arm sticks against it and depresses it in rest mode leaving the lights off. As the pedal is depressed forward, the button springs out and the lights come on. It is very very hard to get it off and replace it due to access, but cheap if you can get at it. I just pushed the pedal in and then pushed and manipulated the button to free it in and out and stop it sticking and its been fine for ages now, the problem never came back, so try that first before trying to get a new one on.
