Been having problem with the brake light switch which controls all 3-rear brake lights.
About 2 months ago i noticed all 3 light were on even when the brake pedal was not pushed, i adjusted the switch so that they come on when the pedal is pressed- all ok for a few weeks, then one day i noticed the brake light don?t come on at all. I purchased a new switch from gsfcarparts and i noticed the plunger section on the new switch was longer so maybe on the old switch it was jammed.
Fine all ok i thought- then about a month later exactly the same problem happened (plunger partially stuck in- so brakes wont come on when the pedal is pressed). Gsf replaced the part and now this one has lasted less than a week with the same problem.
So is there an underlying fault with the brake pedal or something else which is causing the plunger section to stick in, or could it be all 3 switches are faulty (2 from gsf, 1 the original).
I cant think that there can be anything on the car that would cause them to fail. I used to have a W reg Xsara and the brake light switch failed on that, a new one from the Citroen dealer was only about £1.60, it might be worth you trying a genuine switch, some pattern parts are not a great fit.
ive put a new switch in (original peugeot part). checked the rear and front lights and all seems to be in order and all bulbs work. there was very minor crust on some of the bulbs contacts- but i dont thing anything major- ive given them a clean. i have the feeling this switch will go the same way.
