so i recently bought my GS, everything was fine until the left blinker in the headlight stopped working. I have checked all the fuses both engine compartment and under dash and passenger side are all ok. when i hit the left blinker on the turn switch it binks 3x inside the car but outside nothing happens. These are aftermarket headlights that came with the car from dealer. The weird thing is when i use my key fob my left mirror blinks and rear light , the right side is all ok. any help?

 

Is the blinker halogen or LED? If its LED, most likely bad electronics. If its halogen, check the bulb and the wiring. This is why you stick to OEM. Car looks good btw.

If you want to save the headlight, take it off the car and then take it to a computer repair shop and see if he can find the issue. LEDs don't run straight off 12.8volts so they have a ton of small parts that can easily go bad and because its aftermarket I would suspect that the engineering that goes into the building the electronic components to be subpar. Someone might've decided to install new headlights because the originals were faded to yellow.

 

It seems like more and more folks have purchased these aftermarket headlights and are having issues. Unfortuantely, if i had to guess, its another case of a defective headlamp - as Red4GS mentioned, it can potentially be fixed if you take it to the right place (either a local body shop or maybe a place specializing in electronics/headlamp repair).

One long shot is go back to the Dealer you purchased from and see if they are willing to offer a good-will discount to fix it. These are typically made in China, plug-and-play headlamps so you may be able to purchase a single headlamp to replace if needed from eBay sellers.

Here's a reputable (based on their feedback) US seller that has these headlamps on eBay ... maybe you can reach out to see if they offer troubleshooting/fixes or maybe strike a deal for a replacement with their unit: https://www.ebay.com/itm/226502002780

 

thanks for the input it’s really weird. when i hit my left turn signal it flashes on the dash 3x then stops, sometimes it doesn’t even work when i hit my switch for left. i was thinking of trying the flasher relay, just need to figure out where its located, maybe something not working right or maybe it could be my switch. i thought of also unplugging battery to try and reset the led boards in the headlamp, but scared to disconnect my battery in fear it might reset everything. Those lights on ebay are almost $900, i did reach out to them to see if they had 1 for sale

 

"3 time then stop" sounds normal if you are not engaging the turn signal all the way. First position is when you're changing lanes, it'll flash 3 times (or whatever you have your setting to, it can go up to 5 times).

If you push further down, it will engage the actual turn signal, which will remain on until you turn then recenter the wheel (like every other car) or when you hit the turn signal in the opposite way to cancel.

To remove the turn signal switch out of the equation, just hit your hazards. If the turn signals don't turn on then issue is likely with the lights. Of course easiest would be just swapping in an incandescent bulb to see if it works. Will cost you less then mucking around with a multimeter.

There is no flasher relay. It's all electronic. Being you have eBay lights, they are you likely culprit. But first test...
