Front Marker Lights Malfunction!!!..HELP!!!
As the title suggests, I have a "Front marker light malfunction"..It wouldn't be an issue , but when I turn on the blinkers, they work fine. When I lock and unlock the doors, they blink. The issue is rather when the headlights turn on the marker lights fail to turn on. They were replaced by LED's about 6 months back and worked flawlessly up until this point. By the way, both right and left have the malfunction...
Question is, is it the bulbs themselves, or is it something deeper as in the electronics or wiring?
Please help steer me in the right direction.

Well its a simple system if its not the bulbs its the wiring. use a voltmeter to check and remember not to get electrocuted!
