Fuse Diagram for part# 9119444... Fuse panel is buzzing

cprovenzo · 04-08-2026, 06:28 AM

Hello everyone, so I've been having a hard time finding a detailed diagram for my fuse panel, seems like all my searches keep pulling up a different 1 series fuse panel than what I have. My part number is 911944, does anyone know where I can find one? I have the card that attaches to the glovebox, but that doesn't have the information I need. My issue is one of the relays that is part of the fuse panel board is buzzing. I need to know what this relay is for and how to possibly diagnose what's causing the issue...any help is greatly appreciated!!!

I should have noted the relay in question is the one I'm pointing to in the pic...

I had a similar issue with this relay buzzing. It got worse during hot days. Turned out being the CAS module.
It will eventually get worse, symptoms such as buzzing, random clicking noises coming from the fuse box. Headlights and taillights staying on,etc.
Does the buzzing start when you unlock the car?
Does it do any clicking noises if you go in accessory mode? (Pushing engine start button, but without pressing the brake pedal)

I've had issues with this Relay too. Don't have a diagram but it would also cause the emergency flasher and other lights to come on and off. Eventually drained the battery.

Replace the fuse and you should be good to go, I found one at Autozone I think. I remember having a really hard time finding the right part number for it though, sorry.
