I have changed bulb on driver's headlight but dim still will not work. This is 2005 nissan altima

It could be the wire just before the headlight plug, or as it is sometimes referred to, the pigtail. I just had one go on my camry after changing the bulb. If you have a multimeter, you can check for voltage at the plug with the headlight switch on. If there is no voltage there while the other lights are all working, this may be your issue. These can be purchased at auto parts stores. Just need to know what type of bulb it is for. It includes the plug with wires and you just need to cut off your old plug and splice in new one with wire
connectors.

try another fuse. check that all bulbs work. If fuse blows again in a short time, you have a short in that circuit- a broken wire or wire that lost insulation and is contacting metal. It may or may not be near the bulb you replaced.

Sounds like poor contacts. Is the other side bright?

check the light fuse...

This seems to help the most. http://www.paulstravelpictures.com/Nissan-Altima-Headlight-Bulb/Nissan-Altima-Passenger-Side-Headlight.htm
He can give you driver's side directions also.

i found answer on Yahoo Answers and Nissan forum. Thanks anyway but don't answer.

Need to disconnect ground to battery before replacing light bulb or fuse will blow. Fuse is located in engine compartment next to windshield washer fluid.

does the lite stay out on high and low or just low could be you dimmer switch

Have you taken your Altima to a dealership in a while? There was a recall on the 05 Altima for misalligned headlights...thus resulting in poor lighting quality...this could be the reason as well...

you have to remove the bulbs from inside of the hood in the engine compartment. in some cars you have to remove some "pins' and remove the entire headlight assembly.. You then remove the holder where the lightbulb is located and replace the bulb.
