Ibiza-97 electrical problem

Good what are you? I am new in the forum ... and I had a question to ask you. You will see a Seat Ibiza from 97 to which the light bulb of the courtesia (the q is on the in the in the beef) to give a change to the car ... before it was yellow ... and now it is blue. Well, from a while ago the light when I put it in the position to turn on when there is an open door ... and all the doors are closed, sometimes it does its function well, but other times I do it on ... even if it stands all the doors and everything well closed .... I suppose it will be some kind of contact that this evil in some place ... but I would like to know if anyone has happened to it. Greetings and thanks in advance.

Hello sparkfun, the failure is easy for you to have it in the ceiling itself where the light goes, since it turns on by contact to mass (it always comes positive).

Possibly in the palanquita that regulates the functions of the light there is something that is playing on the roof or in a cable and when you get potholes or touches the lamp is turned on alone.

Another cause (much less likely) would be that you had some broken door switch but you would always be on or not on when you open the door where the breakdown was.

All the best.

Thank you very much megabeat_1, because this weekend will put me in a little while with the car I have if I can fix it ... that I already get tired having to be baffled every time it fails ... hahaha good greeting and thanks again.
