I just changed out my HID bulbs. Now my passenger side high beam doesn't work. When I flick on the high beams the drivers side projector opens up and I get the full light, but no such luck on the passenger side?

Does anyone have any ideas what could be wrong? The low beams work just fine.

 

So you know, there isn't a separate filament for high beams. It's just one filament ant there's a shutter in the headlight assy that moves when you switch to high beams. You may not have seated a connector all the way back on or somehow upset the shutter mechanism when you changed out the bulb.

Google --> "site:tl.acurazine.com hid shutter" without quotes found
one high beam shutter won't flip --> https://acurazine.com/forums/3g-tl-problems-fixes-114/one-high-beam-shutter-wont-flip-776727/ Perhaps the fuse is your issue. Check that first for sure.
