I just installed HID's in my fogs, but only the passenger side works? I swapped everything from one side to the other and still the same result. The driver side will not come on no matter what combination I use and I know that they both work. The original bulb works and I am getting 12volts. Can someone help me with any suggestion. Thanks in advance.

 

Have you tried reversing the connection between the car's harness and the ballast?

That did the trick for me.

 

Nice one dude, thanks a lot didn't even think of that. Yeah they had the connections switched from cars harness to ballast. Thanks now all is good.

 

Glad it worked out
