    Take it up to advance. Get yourself a Haynes repair manual. They have the wiring diagrams in them. If it is your alternator you would have issues keeping a battery charge. Hopefully it is just the wires messed up on the switch though.

Likely when the brights switch was replaced, something got tangled, or misplaced. It likely worked fine for a while, then the connection was messed up when it was bumped or something. I would read the repair manual to be sure of the wiring diagram. It should be an easy fix, just have to pull off the outer switch cover I think, or the steering column cover. Not sure of the switch on that exact model.

    I think it is the drl relay

  • bones5406 Nov 29, 2014

    Yes that drl could do it too. You could disable the drl, but that is tricky to do. Hopefully it is an easy fix.

SOURCE: Dim Headlights/headlight problem

if that is the case i believe your altenator is bad and draining the battery the altenator runs the engine and charges the battery the battery starts the vehicle and runs all the electronics and accessories the regulator is not working and therefore the battery is not getting charged and as the vehicle is running and the lights are on they will get dimmer and dimmer until there is no voltage left in the battery. reploace the altenator and the problem will go away...please rate this

SOURCE: 2004 Cavalier Day/dim lights not working

I finally got mine fixed!! It was the crossover wires between headlights(the wires that run in front of the radiator). One wire was torn into. Spliced them and taped back together. Hope this works for you!! I also used something called wire caps that help hold the spliced wires together. I found this solution on yahoo.com search engine where someone else had suggested this. My only problem was no dim lights, but all the other lights worked fine.

SOURCE: one headlight turns off and driving lights when brights turned on

First, it is a factory setting that turns the running lights off when the bright lights are turned on, so that's nothing to worry about. Now the headlight issue could just be a bulb. If this has a headlamp for both high and low, it is possible it just blew the high beam part. If there are seperate lamps for high and low beams, then try replacing the bulb. It should not be an electrical problem unless you had to remove or disturb alot of parts to change the wires and plugs. Let me know if this helps :)

When switch headlamps from brite to dim they go out also drive light wont come on


First I would suspect the dimmer switch on the steering column or wiring in the column. Second I would suspect a bad ground wire or ground connection. Here is link to a forum where others are having lighting problems with daylight running lights. The whole DRL system is rather a complicated maze of relays and connections, any of which could cause your problem. The tip on the forum to get a wiring diagram form Autozone looks like a good deal.

I have running lights in the day when i turn my headlights on i have no dims but i have brites..


first check the light bulbs, I've seen case where both dims were burnt out. Some running lights use the hi beams, some with a resistor so they are not as bright in the day. then check the relays, many times there is another one of the same ## and you can switch them around to test.

Hello, I'm having an issue with my headlight. For almost a year now I do not have a dim (low) headlight on my passenger side of my 2002 Chevy Impala. My Impala has over 140,000 miles and a 3.4 Engine


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 .

Both headlites are dim brites are fine


Headlights naturally become less bright over time. If the bulbs have not been replaced recently, I would start there. Look around the lamps for any damage, brittle wires/connectors, or signs of burning. If there is a wiring problem with headlights it is almost always right behind the bulbs.

Turn you headlights on and see if you can twist the headlight switch clockwise. Your dash lights have the ability to be dimmed for driver preference

My 2003 Chevrolet Impala has a problem with the headlights. bright lights work dim lights do not work. the light bulbs seem to be fine.


If you are 100% sure the lights are ok, it's going to either be the headlamp relay or the high/low switch. I'd swap a bulb for a new one before moving on to more troubleshooting.

Hope this helps.

Follow the ground wire ( black to the raditor suport and reconnect it or add aground wire from it to the battery ground and it'll work good. Bet it goes out if you unplug the other headlightas it's grounding thought the other light.

You need to buy a whole new clicker, same thing happened to me, eventually your bright lights will end up not clicking off or vice versa. and your turn signals will mess up. Get a new clicker, it's the easiest solution, but not the cheap one. mine was like 200$
