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 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’m going to try checking wires because the alarm and door locks don’t work right. Thank you so much.
@@KITS_Auto_and_Truck_Repair I want to share this with you. I had a problem where the parklights were intermediately switching on while driving my Sandero Stepway 900T 2017 model. It turned out to be brake light bulbs that I recently fitted were of poor quality. The bulbs were turning black yet continued to work. I fitted better quality bulbs. So far the issue has stopped. The dash is not flickering. Especially when I press the brake pedal. I'm sure this will help too
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.
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 🇬🇭
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?
A very good video. you explained it clear and perfect the color coded map etc... 100% I can learn from you 🙂 keep up the great work . I'm from Brooklyn New York
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 Altima......
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?
