It's worth mentioning that when you are working on lighting circuits that are current monitored (like this one) current draw that is too low can also cause issues. Make sure the light has the bulb that it was intended to have from the factory. Some cars can be so picky that even using a bulb that physically fits but has a slightly different wattage can cause the module to shut down the circuit or set warning messages for that bulb. LED replacement bulbs or HIDs can cause problems as well since the current draw is different. HIDs have a very large start up current which could be interpreted as a short, Leds could be interpreted as an open circuit.

You are right about the bulbs. In the mid 80s, I think 85, on New Year's night, after ringing in the new year, I got in the car, started it, turned on the headlights, and both flashed and went out. Clicked high beams, had them. Low beam, dead. What can it be? Bad switch? Bad relay? Ground? I thought surely it can't be, but I went the next day and bought 2 new sealed beam headlamps to replace the aftermarket halogen ones I had installed a little over a year earlier. Had low beams again. Check the bulbs first.

I've got a weird electrical problem with my Chevy sonic. For some reason if I put the windshield wiper on and turn it off in the middle of wiping, sometimes the wiper stops and gets stuck where I got to turn it on again and turn it off then it will go all the way down. Weird. Also my driver side auto up or down window won't shut sometimes. So i'll it the auto up and the window will go all the way up but then go back down on its own. Something weird is happening.

It takes skill to have luck! You found those green crusties because you were bright enough to look. I suppose I might have found it by checking circuit resistance from the connector at the BCM, or maybe current when powered independently. It's a little disappointing they use the BCM to electronically bypass the circuit without setting a code to guide investigation. Old time fuse checking for each circuit was too easy.

Whenever you don't see a circuit fused and the power source comes from a module the module will sense the amperage pull on the circuit and discount itself should the amperage draw exceed a predetermined level. Otherwise, the module becomes a very expensive fuse. When this occurs it is possible it will also set U codes. Great job as usual.

Not too hard to follow the nose in burned electrical circuits. Have donr that myself, just not on a car.
Love the videos.
I still hate new and late modle cars and trucks.
I retired from doing electronic stuff, (being nice, I just want an older beater, to run around town in: that I CAN WORK ON, with duct tape and superglue.

Electronic components have distinct odors when they fail. Capacitors will smell different than Integrated circuits or solid state (silicone based transistors) Resistors are mainly carbon, and coils have a lacquer based insulation. Wiring has plastic insulation, the newer stuff smells differently as it's soy based insulation.

my wife drives a 2010 E-nox those tail light buckets, I lube those plastic pins / bushings.
we have 56, 000 on the car. sucks engine oil, always has. 4 banger, other then she bringing it home with
dings and dents, all around it, a cam positioner went bad & that's it. short distance driver. sits
in the garage.

Hey I just grabbed one of your videos to say you are awesome! 65 an hour you are dirt cheap and one of the best in diagnostics I have seen. Short of my hs shop teacher! lol Thanks so much for everything you do and for putting it out for the world to see!

I use a flat screwdriver and a cloth to remove the taillight. I put it in the gap in between the plastic lens and quarter panel and wiggle it back and forth. No chance of damaging it from yanking it off. Works great for the stubborn ones.
