2002 nissan maxima , parking light on driver side not working. checked bulb and light housing. both good. what else should i check for before entering hariness???

Are you sure you replaced the bulbs with the same brand/model as on the passenger side? There are a lot of different versions with different light colors and intensities.
If so, have you made sure there is no water vapor in the headlight housing, and that the silvering inside is not degraded?

Check the headlight plug first, see if you have 12 volts and a ground when the head light is turned on. You may just have a burned headlight connector.

Could be either one. I'd start by checking the fuse, and if it is okay then checking the bulb. Both sides could have the bulb go out at the same time, but it is more likely the fuse, and the brake lights work off a different circuit. Hope this helps. Good luck :O)

this is the light in the rear bumper. this light pops right out. slide a small plastic wedge bettween the rear of the light and pop out or go from behind the bumper and push the side arms in and push light out. look at new light and you will see what am talking about. good luck.

check the brake light for loose connection or moister or bad bulb.

Check for broken cables, proper ground to body, if headlights have diferent circuits if does, check individual fuses.

loose ground conection check wiresin harness
or worn contacts in socket asembly

jorgeva: on the driver's side to gain access, you must remove the air cleaner assembly. At that point, you can see the back of the light which has a plastic cap. Rotate this "counter clockwise" and you can pull it back from the back of the lamp housing. From there you will see how the bulb it self is plugged in, which is obvious. Unplug it. There is a "spring "like latch retainer to hold the bulb in place. Unlatch it, remove the bulb and install the new bulb.
CAUTION!!!!!!! DO NOT TOUCH THE GLASS AREA OF THE NEW BULB! Only handle the rear section. Reassemble in the reverse order.
The right side will require the removal of the windshield washer tank.
I trust this will have answered your question. If you would, let me or FIXYA know if I have solved your problem......

Unplug the bulb and look inside the connector, you may have corrosion in there. Also check the connector to the headlight housing for corrosion as well.

check the fuses- some car makes uses individual fuses per side. Just saw that in a mitsubishi- I believe Nissan does that too. Those fuses are probably under your hood.
