Hello together with me all 4 windows do not go down or up before about 3 std I didn’t have the test, I looked for if maybe the safety is broken but that was just humming out of the safety box when you press the switch now I have the presumption that the relay for the window lifter is broken can tell me if the is in the safety box or hidden in any door Peugeot 406 110 HDI BJ 2001 Thanks in advance Gruss Denis
