I have a 2000 chevy malibu with headlight problems. ... High beams work correctly.... I suspect a ground problem but cannot locate the ground cluster. ... Grouped together there, one pink wire to the Headlamp Switch, and one to ... my Wife's car has lowbeam on the left side that just won't work and now the ...

Headlights grow dimmer by up to 20% over time and eventually burn out - for this reason, we recommend changing your headlights in pairs. Changing both headlight bulbs on your Malibu at the same time will allow both bulbs to have the same intensity and prevent the new headlight bulb from appearing brighter than the bulb on the opposite side. In some Chevrolets, the highbeam is the same bulb as the headlight and it is possible for the highbeam to work, but the headlight be burnt out even if they are the same bulb (and vise versa). Some Chevrolets have high intensity discharge headlights, sometimes referred to as xenon lights. These bulbs have a very high voltage that runs through them, even if the battery is disconnected. If your Malibu has this type of bulb, we do not recommend that you attempt to change it yourself.

When you change the headlight on your Malibu, it is important to not touch the glass part of the bulb with your fingers because the oil from your fingertips will cause that part of the bulb to burn hotter, which significantly shortens the life of the bulb.

Hope this helps! :)

If the relay were the problem both sides wouldn't work . Do you know how to do automotive electrical testing ? How to read a wiring diagram ? You can view wiring diagrams here http://www.bbbind.com/free_tsb.html Enter your vehicle info. year , make , model , engine size . Then under system click on lighting , then subsystem click headlamps . Click on the search button , then on the blue links one at a time . At the top of the first diagram you will see the fuse's for low an high beams . The fuse's send B+ voltage directly to the high an low beams , from there B+ voltage goes on to the dimmer switch shown on the next diagram .Low beam headlamps from the dimmer swich goes through the headlamp relay when energized by the BCM . When the relay is energized that compleats the circuit to ground at G- 201 . So you see if one side is working it can't be the relay . Doing electrical testing , voltage drop testing is the way to find the problem .

How to read an electrical diagram Lesson 1

low beam not working could be relay or bad contact at stork control. Fog lights should only work with park lights on. not supposed to be on with headlights like in the movies. This is illeagle in australia to have head lighs and fog lights on together as well as being dangerous to other motorists

have you tryed replacing light bulbs if so check relays

the filament on the low beam burnt out. but the high beam didn't. You have a filament for each. 1 for high beam and 1 for low beam in the same light bulb. You need a new head light.

sould chane the headlights

Head lights can be a pain at times but before jumping to conclusions... Have you taken the low beam bulbs out and checked the continuity on them...
The filaments could break and then make a short term contact causing your right lamp to come back on.
Check the bulbs with an ohms meter first before searching for more difficulties.
