Brake lights problem

[bod94]

Hi I have a Renault megane 1.6 petrol 2005.
The car has been sat for around 4 months.
Yesturday I jump started the car to check if everything is working. I noticed one brake light works ( passanger side)
So today I decided to take it apart to change the bulb. Before I did take it apart I checked again and the brake light did not work anymore ( but the centre one above window does).

So tested bulbs and they work. Checked voltage going in and ive got 0v. I don't really know how the breaking circuit works so I am not able to check anything else.

I would imagine there would be some kind of switch where the brake pedal is but due to the centre break light working I wouldn't think that could affect it. (Unless it has multiple of wires)

Any ideas or circuit diagrams?
(Aparently they are in sticky... but I can't find them)

Check fuses. If it was the switch, the middle light would be off too.

I have found the problem. The connector pin slightly came out. all fixed
