Re: no low beam lights
These cars have a problem with corroding wires in the front. One area is in the middle front behind the bumper slightly toward the passenger side. In this spot they join three wires together that rot apart. They are also known for a spot along the drivers fender. Please rate.

Go to your local auto parts store and buy some new ones. They will help you put them in. It sounds like you lost the low beams. When the low beams go out the high beams will still work. It just sounds to me like the bulbs are out. if not they shouldn't charge you for the bulbs.
if the fuses are good then you need to check for power and ground at the headlight plug that attaches to the headlight bulb if you have a good power and ground there and the connections are good then the bulbs are both no good.or if you can tell the bulbs are burnt out by looking at them then you don`t have to check powers and grounds.you also can directly feed power and ground to the bulb and check both the terminals for high beam and low beam as you cannot tell which is which by looking at the terminals
should be three wires one ground one power for low beam one power for high beams
take a test light (if dont own one buy one there real cheap and useful) clamp test light to good ground turn on lights on low beam probe wires in connector until test light lights this will be low beam power
no switch to high beams should have power on other wire
this could be solved by taking the bulb out of its holder and cleaning the contact of the bulb and holder.
turn the ignition on after this with the bulbs in the holder and plugged in but not in the headlight kitself.Turn the lights on and see if the work if still the same try moving the bulb while on in its older and see if its just loose. if so holding it one way it will work. wedge something something to hold it in place or buy a used bulb holder.
Check the fuses at the same time and the wire plug that powers the bulb. check and clean the contacts of these also
Let me know how it goes and ill help again if it persists. email@example.com
about troubleshooting your headlights on your vehicle. I would isolate the wire that comes from the headlight switch to the headlamp bulbs for low beam and check to see if there is a short in the wire. You can find this wire by using a test light turn on the key and get a good ground with the test light poke the wire and see if the test light illuminates with the headlight switch on. ----Also check the wires, and check the fuse for your low beams. could of blown a fuse on your lows, but your highs will still work. Every single time I have had a failure of low beam in a headlight without failure of high beam, it has been because the lamp bulb or halogen lamp module has reached the end of its serviceable life, not because of any wiring problems. Low beam burns out first because it is on the most. If low beam is lost simultaneously in both headlights, I would check fuse first, then the headlight switch. If low beam is lost on one side only, it is almost always going to be due to the bulb or lamp module needing to be replaced. In that case, replace them in both headlights because the other one will be going kaput in short order, as well. There is something to check. Does the low beam relay click when you turnt he low beams on? if it does not click then Then find the BCM at the base of the steering column. In there find the grey connector and in there, find the pink/white wire in terminal A4. Use a wire to jump that wire to ground. IF the low beams come on, then it is likely the BCM is bad. Also check a bad wire between the fuse block and the BCM. before replacing the BCM . Start under the fuse block. This is the fuse block under the hood. This will
help. Thanks please keep
updated.please do rate the solution positively .thank you for using fixya

Most like the low beam filiment is bad but the high beam filiment is still good, try replacing bulb. If replacing bulb does not fix problem then you probably have voltage problems and should check the voltage reading and the plug. OR isolate the wire that comes from the headlight switch to the headlamp bulbs for low beam and check to see if there is a short in the wire. You can find this wire by using a test light turn on the key and get a good ground with the test light poke the wire and see if the test light illunimates with the headlight switch on. check the wires, and check the fuse for your lowbeams. could of blown a fuse on your lows, but your highs will still work.
The fuse box is located in the engine compartment,on the driver's side. Has thumb-screw retained cover.

Power flows from the battery to the main fuse. Then it flows to the control coil and contact side of the headlight relay. When you turn on the headlights, the headlight switch provides ground to the control coil in the headlight relay and that operates the contacts. The contacts allow power to flow to the right and left hand headlight fuses. Power flows to the headlights. The headlight switch is what provides ground to the high and low beams on the headlights.
To diagnose, remove the headlight relay. Using a voltmeter, check for battery voltage on terminals 3 & 4 in the socket with the key in the RUN position. Then turn on the low beams. Test for good ground on terminal 1 in the socket. If you're not getting ground, then you've got a problem with either a bad headlight combo switch or a bad ground. If you get good ground on terminal 1, reinstall the relay, turn on the low beams and test for power in the headlight sockets. If you get battery voltage, that confirms you've got good fuses and wiring up to that point. Next, check for good low beam ground on the red/green wire in the bulb socket. If you're not getting good ground, it's either a bad combo switch or bad ground from the combo switch. Then turn on the high beams and check for good ground on the red/yellow wire in the bulb sockets.
It wouldn't hurt to clean the ID ground on the left side of the instrument panel, but based on everything you've said so far, this sounds like a bad combo switch
