ELECTRIC PROBLEM SAXO VTS

Well, I have another problem with this car, I have stopped working the flashing, electric windows, heating, air conditioning, and assisted direction, I have looked at all the fuses, including those of the habitaculus and those of the engine, and everything is fine, but there is something else, if you accelerate up to 3000 revolutions, the assisted direction is activated and the heating is not the other They work normally, but if I don't accelerate up to 3000 laps, they don't work ..... is it to go crazy ... can anyone tell me what can be due ??? They have told me to look at the masses, but they are all very fastened ... thanks in advance

can it be some relay ?? or alternator ????

Good night barracuda, for what you say and if you have no problems in the load system, what can happen to you is that the BSI (control switchboard that sends all that) has a problem; if after resetting it (disconnecting the negative of the battery for about 20 sec.) Follow doing the same then you have to take the car to an official workshop to change it and that you will be telecoded.
All this assuming that your car, according to its manufacturing year already begins to mount this type of switchboard.

Apollo a Jose The BSI Command Unit gives a gigantic can and commands emergency lights, elevates moons and other things.

Thank you very much for really answering, I will take it to put it to the fault computer and see me, greetings
