I remember this vehicle, it was diagnosed as a bad alternator. No technician likes a come back. But your persistence and knowledge finally got to the root of the problem. I hope the customer was understanding. There is no such thing as a perfect world.

You may not realize it, Deo but you just taught a very valuable lesson in doing due diligence and perseverance. And something else that DIYers always need to learn, which is Stay Calm.
You were frustrated but it didn't show. You just kept going. You are a great example of a top notch mechanic. Thank you so much.

You are a star, had a similar problem with my Golf MK4, disconnected my alarm system everything is ok now.

[danniebosley]

You are efficient and thorough!
I was able to clearly understand and follow through with you to the end.
I have a 09 Avalanche that’s doing the same thing.
I’ve replaced the battery, alternator and cleaned all ground wires in the engine compartment.
I was at a loss for where to go next.
I’m going to try checking wires because the alarm and door locks don’t work right.
Thank you so much.

[lesliegovender]

Thank you this is so detailed. You perform a detailed check. Makes all the difference. Great stuff

I have the exact same problem, surprisingly I think its the connection to my door too. It's a Toyota Yaris hatchback. I almost ruled it out as a bad alternator, although I eventually had to change my battery (it was already bad). The flickering stopped a while ago when I kinda slammed the driver door (not intentional though 😅. I'll keep observing to trace the exact location of the faulty device. Thanks bro.. you're a life saver! Cheers from Ghana 🇬🇭

You make learning wiring easy to understand

Thank you for the in depth troubleshooting, I will use this procedure to troubleshoot my problem with a 99 Ford Ranger flickering headlamps and dash lights.

[bartscave]

What a frustrating diagnosis for you! Great job.

I had a similar problem with slight flicker, remote key frequently not working even after replacing the key battery, key fob and car battery dying after the vehicle sat unused for weeks. Turned out to be a defective GPS tracker installed by the dealer because they wanted to track the vehicle if payments were not made. Finally paid off the vehicle and sold it because it was a terrible car due to A/C Auto climate control, power steering and CVT issues, 2013 Nissan

Thanks again for this video. Could you add a video and link on how you used your test bulb, for the newbs like me?

[davidmoore]

Good video. I was most interested in your concluding statement. Why and what to do or not to do. You said the faulty part was after market ? Was it still needed? Also the cheap wire connectors what connectors would you recommend?

[Usmanthemecano]

That was a tricky one! Bon boulot frérot !

[bikerleo]

What was connected to the interface module? there could be a number of functions connected to that module Tachometer, door locks and locking systems a car alarm were any of these attached and causing a fault and then you might think it is just the module but what if it was a door lock?

[LonelyHeartsChannel]

I am no electrician and I have this problem and I want to change the module myself but you don't show how. It's easy for you but not for the rest of us. I watched your 30min+ of agony but you leave me hanging in the end when you got your victory.
