No Low Beam Headlights; A/C Problems

I have a 2002 Jetta 1.8T and right now I am having a problem with the low beam headlights. Once you turn the headlight switch on, the daytime running lights turn off, and the instrument cluster lights come on, but the low beam headlights do not come on. The daytime running lights run off the low beam filament in the bulb, and the bulbs are good they were just replaced. The fuses are also good. I even put a new headlight switch in thinking it was that, but it didn't fix it. When the headlight switch is turned on the green and yellow wire running in the back of the headlight switch harness has no power, but if the switch is in the on position it has power. Another problem I am having is the air conditioning clutch does not engage to run the pump. There is constantly 9v of power there whether the A/C button is on or off. Also, when you push the recirculate button the brake light comes on on the cluster, it beeps at me, and I lose power accelerating.

There is usually a relay under the hood that controls these. They could be run in a series which would explain your lack of a blower motor also. Good Luck.

SOURCE: No Low Beam Headlights

but the daytime running lights do function? before you turn the headlight switch on they work fine? i'm asking because the drl and the low beams use the same ground. you don't say that the high beams work but i'm guessing they must or you would say. next thing to do is take the headlight assembly apart, remove a low beam headlight from the socket and see if, with headlight switch on, you have 12 volts between the low beam socket and ground. if you don't i would say that you have a faulty wire between the headlight switch and the low beam sockets. hope that helps

SOURCE: 2004 jetta headlights going out when switching low/high beams

There is no recall regarding the headlights on that vehicle.

What typically happens is the wiring inside the light housing melts and the bare wires randomly touch each other.

You can verify this by taking one of the plastic covers off the back of a headlamp housing and checking out the three wire harness inside. It is extremely common for this to occur on that vehicle.
The wiring can be repaired, though difficult without removing the lamp.
If you wish to replace the wiring with factory replacement parts, there is no service parts for the lamp, you must replace the entire housing unfortunately. For this reason most people just repair the melted wires.

High beam and low beam not working together.


I think you just need new bulbs in both sides. The High and low beam are in one bulb.

I have a 1995 Ford Explorer Limited and the high beams work but the low beams and fog lights do not, please help....


These trucks are known for bad multifuction switches.
the switch that i talk of is the signal switch , the handle is the switch, it bolts to side of steering column . this switch controls the signals and the headlights and high /low beams. the other thing is the headlight switch connector, the connector some times goes bad and starts to melt or just comes out of the connector. you will need to remove the cover to steering column, the screws are located under the bottom cover in holes. remove cover and check connector and then test for power if you have power going into switch but not coming out then switch is bad.

the last thing is to make sure the bulbs are good , make sure the headlight bulbs are good , and also the driving light bulbs, test for power at the connectors to those lights to.
You will need to do a little testing to find the problem.

NO headlights. Could a timing belt issue be the


absolutely not the timing belt has no connection to headlights,first locate and check any headlamp related fuses located in either fuse box underhood or in dash area if no lights on high or low beam may pull headlight bulbs and check unlikely both go bad @ once this may end up being multifunction switch on steering column your turn signal lever is what you pull back on to switch rom high beam to low beam correct? if so this switch can cause your problem

2002 pontiac grand prix gt. High beams are dimmer


A loose ground wire to the headlight will keep it dim,Or a headlight adjustment will bring the headlight up.If you can have your headlight turned on a garage door or something at night,and then watch as you change your headlights from low beam to high beam which ones are higher.the last thing to verify is that your high beam headlights are not the plastic lens type that turn dull which cuts the light power.

No headlights


You need to start by checking the fuse for your headlights (low beams). The DRL could be be bad, but I have not seen them go out very often.

No Low Beam Headlights


None of the above solutions are correct. Here is the correct solution:

The problem is in the high beam switch assembly which also houses your turn signals and possibly cruise control. There are some electrical contacts in the assembly which dis-connect the low beams when you put the high beams on. Constant use of the high beam switch will create arcing on the low beam switch which makes the contacts not conduct electricity anymore.

The repair is to either replace the assembly, $300 at dealer, $100 or less do it yourself, or take the assembly apart and clean it for free. (2 hours or less)

P.S. If you own a VW, especially around model years 1999 to 2004, there is a rare but devastating problem with engine coolant being literally pumped through all electrical parts of your car.... destroying it. Repair cost = $8,000. It is called coolant migration. Check your VW right now (takes two seconds, literally), and do a two-minute procedure to fix your car to prevent the problem here: http://www.myturbodiesel.com/1000q/multi/coolant_migration.htm

There are fuses for left and right low beams. Headlights on low beam, use a test light, see if voltage on fuse circuit? If no voltage that will lead us back to dimmer switch or problem with wiring circuit from dimmer switch.
