Thread: electrical randomness

well every time I hear that click that's when everything stops working correctly. would the BCM cause all these problems? I have checked the fuses a couple times. I will find the wiring diagram for the BCM and check them. is there a way I can test the bcm to make sure that needs to be replaced? sorry just on a limited budget right now. would that also cause the locks to not work sometimes and the security light to stay on sometimes?
