I changed my halogen headlamps to LED Halo headlamps and now only the passenger side turns on. Before I did, I verified both halogen headlamps and all turn signals and everything was working properly (important note: all lights are original and not LED except for the new headlamps). I then swapped the LED headlamp from left to right and right to left and still only the passenger side comes on. But at least this tells me both LED headlamps work. Here is what I know to this point after trouble shooting: all wires are in good condition and repaired if any damage was noticed, polarity is is the same on both headlamps, all ground connections have been cleaned and resecured, and all relays and fuses are good. Then I put one halogen into the passenger side and put one LED headlamp into the driver's side and both lights came on and worked fine. I put both LED headlamps back in and I'm still where I started; passenger LED headlamp turns on and the driver's side LED headlamp does not. Please help with what else I should try ...I'm out of ideas.
