New crossfire owner, I was installing new H7 bulbs, on passenger side the plastic connector crumbled and the wire connectors touched. Now the low beam works but not high beam on that side. High works on the other side. Hindsight I should have disconnected the battery before monkeying around with the lights.

 

Are you talking about the plastic connector with the wires in it that hooks onto the prongs of the bulb?
If so you might be able to get one off of e bay and splice it, or you might be able to push the wires out and push your wires into the new one.

 

Yes the plastic plug crumbled. I put the wire connectors directly onto the bulb. Btw this happened to the low beam bulb which works fine but high beam on that side no longer works.
Also the left turn signal no longer works. I removed the high beam bulb and tried turning it on, it does burn very dimmly

 

Try replacing the front and rear turn signal bulbs and see if that fixes it. Also make sure you didn't blow any fuses.
For the high beam, clean the where the bulb contacts the socket and the metal part of the bulb itself. It may be a bad ground that's making it go dim. You can use contact cleaner, or spray a little brake cleaner on a rag and wipe both surfaces.

 

I finally figured out the problem. On the main connector for driver side headlight the ground in had got bent snd was barely making connection. Whalah all lights function properly

 

Thanks for the update. I'm glad you fixed it!
