2000 Chevy Impala Electrical problem

[Youngster513]

I have clicking noises coming from both of my fuse boxes and I thought it was the relays so I replaced all of them and the problem still occuring. And while its clicking all my interior lights and my head/tail lights are flickering everytime my fuse box clicks. I was wondering if anybody has any problems similar to mines and if I should get newfuse boxes.

Thanks.

You need to isolate which relay(s) is "clicking"- put your fingers on each one to determine (feel) which one it is. Once you find it, you will know what circuit it is on and how to trace it from there.

The lights dimming may only be a result of extra power draw while relay is clicking- and not the cause of the problem.

Report back once you decide which relay is clicking.

Also, wiggle your ignition switch, does this affect clicking noise?

I found which relay was clicking and it was my Park LP Relay so I replaced that and the clicking sound still continues from same relay.

The Park Lp relay is controlled by the Body Control Module (BCM) See if the ground leg (the one being controlled by the BCM) is going back and forth to ground. Use your DVM digital volt meter to see if continuity to ground is intermittent- probe ground socket of relay coil with voltmeter set on continuity. If so, then BCM is in question- most likely bad.
