Difficulty changing low-beam headlight

Drl only work in daytime not at night ???? Daytime running lamps are only suppose to work in day light hours . Low beam & high beams ? none of these work at night ?
Headlamps
The headlamps may be turned on in two different ways. First, when the driver places the headlamp switch in the HEADLAMP position, for normal operation. Second, with the headlamp switch placed in the AUTO position, for automatic lamp control (ALC). During ALC the headlamps will be in day time running lamp (DRL) operation in daylight conditions, or headlamp operation in low light conditions.
Headlamp ON/OFF control is determined by the body control module (BCM) by a signal on the headlamp switch on input circuit when the headlamp switch is in the HEAD position. When the headlamp switch is in the AUTO position, the BCM determines headlamps ON/OFF by the voltage from the ambient light sensor.
If the headlight switch is left in the ON position, the inadvertent power control feature will turn off the headlights approximately 10 minutes after the ignition switch is turned to the OFF position. If the driver places the headlight switch in the ON position after the ignition switch has been turned OFF, or if the ignition switch is in the ACCY position, the headlights will remain on until turned off or the battery runs dead.
The high beam indicator is illuminated when the instrument cluster receives a class 2 serial data message from the BCM that the high beams are illuminated.

Do you know what the BCM is ? Do you know what DTC'S - diagnostic trouble code's are ?
DTC B2575
When the body control module (BCM) senses a request for low beam headlamp illumination, the BCM sends a ground signal to the low beam headlamp relay through the headlamp low beam relay control circuit. The headlamp low beam relay will apply voltage to illuminate the headlamps.

Check the headlight relays- your owners manual will show you where they are.

[Information] For a 2002 Toyota Camry, the Daytime Running Lights (DRL) operate utilizing the High Beams (inner Lamps closer to the center of the vehicle front) at a reduced power.

[The troubleshooting process:] Review the Owner's Manual and ensure the test configuration matches the following criteria:
1. According to the 2002 Toyota Camry Owner's Manual (Check your Owners Manual):
"The DRL system will make your headlights come on at a reduced brightness when:
The light switch s in the "DRL" position.
The ignition is on with the engine running.
The headlight switch is off.
The parking brake is released."

2. Set the Test Conditions according to Step 1 above.

3. Check the headlight bulbs to ensure they are not burned out. If one burns out, there is a fair chance that the other would have burned out at the same time. Replace as necessary. In this case, if the high beams operate, the DRLs should also operate.
4. Test the system, ensuring the step 1 conditions are set. (Engine running, Multi-function Switch on Turn Signals in "DRL" position, headlight switch off (repeating what the manual says -- it should be obvious that in the "DRL" position, the headlight switch should be off / do not have the switch positioned to "High Beam"), and the Parking Brake "off").
5. If DRL lights do not work, check the engine compartment Fuse and Relay Box. there is a 5 Amp DRL fuse -- replace it with the spare. Test (step 4).
6. If it does not work, swap around or replace relays -- there are three (3). Any one of them could be bad (stuck or burned out). Test (step 4).
7. Other less likely possible issues could be that the Multi-function Switch is broken or a connection / wire is broken. [Beyond the scope of this process.]

My problem was that the test configuration did not have the engine running and parking brake off - Step 1. Problem solved with much thought, repetitive tests on the vehicle and going back to the basics -- what does the Owner's Manual say and where are the applicable fuses and relays located?

your owner manual will list the bulb. It is expensive. tascafordparts.com for discount from Ford Dealer

Navigator high intensity discharge (HID) headlamp

1. Remove the front radiator air deflector.

1. Remove the three bolts and the headlamp assembly.
• Disconnect the electrical connectors.

8. Remove the headlamp bulb protective cover(s).

• Remove the HID lamp cover.
• Remove the high beam cover.
• Disconnect the electrical connector and push the grommet into the headlamp assembly.

1. Release the spring tabs and remove the HID low beam bulb.

do your flash to pass lamps light when you pull the stalk towards you? If yes, the bulbs are ok.
Do the hig beams work?
Your headlamps have sepaerate fuses for each headlamp and you have a low beam relay and a high beam relay under the hood in the black box.
If everything is out, I suspect a bad headlamp switch.
Check car-part.com and look on page with * for cheapest price.

Your owner manual will identify fuses & relays.

PS, You did not recently instal high current bulbs did you? If yes, put originals back in.

HEADLAMPS

The voltage is supplied to the lamp switch through a fuse. This fuse is located in the central junction box in the left-hand footwell.
When the headlamps are switched on, a voltage is supplied to the high beam/low beam switch and to the low beam relay. The relay for the low beam is located in the battery junction box (BJB) in the engine compartment.
If the high beam/low beam switch is set to "low beam", then a voltage is supplied through the low beam relay to the low beam part of the headlamp assembly. The left and right-hand low beams are fused separately. The fuses are located in the battery junction box (BJB) in the engine compartment.
If the high beam/low beam switch is set to "high beam", then a voltage is supplied through the high beam relay to the high beam part of the headlamp assembly. The left and right-hand high beams are fused separately. The fuses are located in the battery junction box (BJB) in the engine compartment.

Parts Required: Change all the lights at once, it is not worth the anguish of doing this over and over again
2 low-beam lights, 2 high-beam/running lights, 2 parking lights - part nos in the owners manual


A can of diet coke to clean the battery terminals is also recommended. *optional



Tools required

Ratchet set : 10mm, 7mm, 6mm sockets
Extension 12"
Large Flat screwdriver, small 4" flat screwdriver and a pair of pliers
Flash-light
12" Magnetic tip telescoping bit

Surgical gloves

Battery terminal cleaner * optional



Step 1:

First take off the plastic cover that cover that is across the front of the engine compartment. 6 push pins hold it in place, Use the long flat screw driver to pry them up and use the pliers to pull them off.


Gently take the plastic cover off and set it aside.


Step 2:

Next you will see 3 push pins that hold the front grill to the engine housing, using the long flat and a pair of pliers pull the 3 push pins out.


Step 3:
In the upper area of each wheel well, you will see a large 2.5" rubber grommet. Pull the rubber grommet out



Step 4:
Locate a 6mm bolt head that is driven vertically upwards. It is not visible looking at the wheel well. You have to lay down on the floor and you will find it about a foot below the grommet and at the edge of the fender. Use the the ratchet to remove this bolt headed screw. It is about a 1.5" long. Do this for both sides before going to the next step


Step 5:

Start with the passenger side as it is easier. Use the flash light and peer into the fender area from the engine compartment. You will see a nut on a bolt, and a plastic fastener.
Use the 10mm socket on the 12" extension. Insert it into the hole where the grommet was, and guide the socket on the nut head. It is about an 1" long. Be careful as you take it off, else you will be fishing for the bolt in the fender.

Step 6:
Pull on the plastic fender in the front till the bolt head and the fastener exit the fender. This has to be repeated for each side.

Step 7:
Locate 8mm bolt heads on top of the light assembly. Note it is not the Philips head - they are to level the lamps. Before undoing the bolts, check the spirit level on top of the lamp assembly and make a note of the bubbles position. You will need this when you put the assembly back. Undo both bolts, they have about an 1" of thread on the top and then you have to pull it up physically or with the use of the pliers

Step 8:
Pull the headlight assembly out - gently. Don't scratch the paint work and don't damage the rubber molding around the light assembly.

Step 8a*: If you see any salt build up on the battery terminals, pour diet coke or pepsi on the terminals, this neutralizes all the salt. Then pour some water to clean the gunk and then with a paper towel dry it. Be careful with the paper towel, as it contains sulfuric acid and is corrosive, put in in a garbage bag immediately. If you feel it has come into contact with your skin, was vigorously before continuing.

Step 9:
Note the position of the connector before you do anything. Turn the retaining rings holding each bulb counter clock wise. When you do this the bulb assembly and the connector will pull free. Two instances of this. Remove assembly, and place securely on a table

Step 10:
Locate the parking light below and turn the connector clockwise as you are looking over it. Pull out the old bulb and replace it. Do this for both sides. Turn on the parking lights to ensure they work, try the signals too. No sense it putting it all back together and nothing works. Replace the holder and bulb in reverse order. Note the unit should fit in nicely and rotate smoothly as you turn counter clockwise this time.

Step 11:
Using the 4" flat screwdriver, lift the locking pins gently and push the bulb out, Start with the low beams. Low beam has only 1 filament, high-beam/running light has 2 filaments. Put on the pair of surgical gloves, and open the pack of new bulbs, push the bulbs into the empty sockets, until the locking pins click into place. Change the low-and high beams.

Step 12:
Insert the bulb with the connector in the position you noted in step 9. Slide the mounting ring and then lock it into place by turning it clock-wise as you are looking at it from the rear of the assembly. Repeat this for both the high beam and low beam. Slide assembly back into cavity. Repeat this for the other side. Test the bulbs light correctly

Step 13:
Gently push back the front plastic so that the bolt and the plastic stud enter the fender. Pay attention to ensure that the fender lining sits correctly. Using the 12" ratchet extension and the 10mm socket mount the bolt back on and tighten. Do this for both sides

Step 14:
Using the ratchet mount the 6mm fastener on to the fender. Do this for both sides

Step 15:
Mount the jack screws on top of the headlight assembly. Tighten till the bubble in the spirit level returns to the original position. Don't push the bolt past its maximum. If it doesn't return to the original level, loosen and adjust the headlamp assembly and re-tighten. Do this for both headlamps.

Step 16:
Replace the 3 push pins that hold the front grill to the engine compartment. Replace the large plastic panel that was removed in step 1 and remount it using the 6 push pins.


Voila - you have changed all the bulbs on the front of the 1999 300M.
