02 pathfinder, headlight still won't work

No you must have a wiring problem if the bulb is good. You can test the bulb out of the car. Do not touch any halogen type bulb with your bare skin.

The HID requires a ballast, did you do any rewiring? Did you check the fuses? Unplug the relay either hi or low, use jumper wire between terminals 30 and 87, the lamps should work, I'm talking about your regular lamps. If they work with the jumper, then check control side of relay.

Me too, same problem here.

check for relay for that light and possible ground wire problem

Make sure the high beam realay under the hood fuse box is working. You can swap the hi beam relay with the horn relay to test. The hi beam filiament in the bulb can be open too.

if it's like a Quest, the relay on the passenger fender controls the left headlight and vice versa.

Could also be the headlight switch, I have seen that too.

it sounds as though there is a loose connection on the passenger side. Check socket and switch bulbs from driver and passenger side. hope this helps tim

The contacts in the headlight relay have probably burned. Try swapping the relay with an adjacent one to see if that fixes the problem

won`t the coolent tube pull out

CHECK THE GROUNDS TO YOU LIGHTS.IT SOUNDS LIKE YOUR TRYING TO GROUND TROUGH A BULB INSTEAD OF A GROUND WIRE.
