Question about 2002 Buick LeSabre

1 Answer

2002 Buick LeSabre Limited RH Headlamp assy

I noticed that the headlamp was aimed much too high. I tried to bring the beam down by turning the vertical adjuster screw. I observed that the adjuster's shank was protruding. It was not sitting flush.
I turned the adjuster, but nothing happened. The adjuster didn't get longer, or shorter. It seems that the adjuster can't adjust in the vertical direction. It was the vertical adjuster, not the horizontal one. Any idea what the problem is?

    Thanks for answering, Abalasa. I had thought of that, but the bulb and holder were properly seated. I ordered a replacement headlight housing, and installed it. I heard a rattling sound when I removed the troublesome headlight assembly. I shook it. It sounds like a nut is rattling around inside. I think either the adjusting (nut?) is separated from the screw, or something else having to do with the adjustment is broken. (This problem surfaced after I had some work done on the Buick).
    I can see several metal clips that look like they might hold the front of the assembly to the rear part. I'm going to try to disassemble the headlight. Maybe I can fix it if it is a loose nut that's rattling around. (Then I'll have a spare, that I hope I'll never need). Thanks again for your reply.

I had the same issue and I noticed that the bulb itself was not screwed in properly. The bulb has 3 small plastic guides that fit in 3 holes in the lamp socket, after which you are supposed to give it a small twist and the plastic guides go under the metal part in the lamp socket; in my case one of the plastic guides was left outside so the bulb was not straight in the socket. Take the bulb out and install it properly, I took the whole lamp out but this is not really necessary.

Right low beam headlight does not come on but my right turn signal will stay even tho i diddnt turn it on. If I cut on my high beams the rurn signal cuts off. Whats wrong? Helo


It could be the lamp control module !
Headlamps
Battery positive voltage (B+) is applied at all times to the lamp control module (LCM) through the underhood fuse block HDLP fuse.
When you place the headlamp switch in the HEAD position, the headlamps input to the LCM is grounded. The LCM then applies battery positive voltage (B+) through the underhood fuse block HDLOBML fuse and HDLOBMR fuse, which feed the left low beam headlamp and the right low beam headlamp respectively. When you activate the headlamp dimmer switch by pulling on the multifunction lever until the switch clicks, the high beam input circuit to the LCM in grounded . The LCM then removes battery positive voltage (B+) from the low beam headlamps and supplies battery positive voltage (B+) through the underhood fuse block HDHIBML fuse and HDHIBMR fuse, which feed the left high beam headlamp and the right high beam headlamp respectively.
Check this fuse in the left under hood fuse box first. HDLOBMR Fuse 18 10 Amp. RH Low Beam Headlamp . If the fuse is good check for B+ voltage with the low beams on . Use a test light or volt meter . If you look on top of fuse there are two metal tabs ,check there for B+ voltage , If no B+ voltage the LCM - lamp control module isn't supplying any .

Why wont the headights or running lights work on my 2002 Buick LaSabre?


There are several reasons why your headlamps an running lights don't work , the headlamp switch is a good one ,plus relays an the DIM - dash integrated module an associated wiring ! Here is how the headlamps work , right out of Buick factory service info !
The dash integration module (DIM) provides battery positive voltage to the signal circuits of the headlamp switch. The signal circuits include the headlamp switch headlamps on signal, the flash to pass switch signal and the high beam input. With the headlamp switch in the ON position, a ground path is available for the headlamp switch headlamps on signal circuit of the DIM through the headlamp switch. The DIM provides ground to either the headlamps high beam relay control circuit or the headlamps low beam relay control circuit of the low beam circuit. The position of the headlamp dimmer switch determines which relay control circuit has ground. The DIM supplies battery positive voltage to the relay control circuits, if the headlamps are necessary. The fuse block - underhood supplies battery positive voltage to both relay switch circuits. When the low beam relay control circuit is energized, current flow is to both low beam fuses and to the low beam headlamps. The headlamps have ground at G103 and at G401. When the headlamp high beam relay control circuit is energized, current flow is to both high beam fuses and to the high beam headlamps. The high beam circuit is divided into a left and right side circuit. The current flow of the left high beam is from the fuse to the left high beam lamp. From the lamp, the current flows to the normally-closed contact of the DRL relay to G103. The current flow of the right high beam is from the fuse to the right high beam lamp. From the lamp, the current flow is to ground at G401. When the headlamp dimmer switch lever is pulled toward the driver, the flash-to-pass switch closes. This grounds the DIM flash to pass switch signal circuit. In response to this input, the DIM energizes the HDLP HI BM relay. Both high beams remain on until the driver releases the switch handle. If the low beam headlamps were on during a flash to pass operation, the low beams remain on. The headlights may be switched to high beam with the opposite movement of the headlamp dimmer switch lever.
By running lights , do you mean park lamps or day time running lamps ?
Park, Tail, License and Marker Lamps
The park lamps, including the license lamps, are turned on when the headlamp switch is placed in the PARK or ON position or anytime the headlights are requested. The fuse block - rear supplies battery positive voltage to the switch contacts of the Park LP relay. When the headlamp switch is in PARK or in ON, the park lamp switch on signal circuit of the DIM has a ground path. The DIM provides battery positive voltage to the control circuit of the Park LP relay. When the park lamps and/or the tail lamps are ON, the DIM energizes the park lamp relay control circuit. This closes the switch contacts. Current flows from the Park LP relay to the LH PARK LP and the RH PARK LP fuses. From the fuse, the current flows to the park lamps. The left park lamps are grounded at G103, G401 and G402. The right park lamps and the right tail lamps are grounded at G103 and G401. The DIMR fuse supplies battery positive voltage to the license lamps and to the DIM instrument panel lamp fuse supply voltage - 1 circuit, for interior lamps dimming. The license lamps are grounded at G401.
The best advice I can give is that you take this to a ASE certified professional repair facility unless your a qualified automotive electric repair person !
Diagnostic Starting Point - Lighting Systems
Begin the system diagnosis with the Diagnostic System Check - Lighting Systems . The Diagnostic System Check will provide the following information:
?€¢
The identification of the control modules which command the system


?€¢
The ability of the control modules to communicate through the serial data circuit


?€¢
The identification of any stored diagnostic trouble codes (DTCs) and their status

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.

Where are the Headlight relays on 2002 Renault clio


The headlamp circuit is rather simple. From the 15 amp RH headlamp fuse, there is a red w/yellow trace that goes to the RH high beam. Out of the 15 amp LH headlamp fuse, the wire going to the LH Hi beam is solid red. Both of these wires should have power when the headlamp relay is energized. The wires from the Hi Beam bulbs going back to the switch should both be red w/black trace. The wire going from the headlamp relay to power the 2 15 amp fuses is white. The headlamp switch applies a ground to illuminate either the Lo Beams or the Hi Beams.

To identify the headlamp beam pattern, look on the headlamp lens. Molded in small letters on the headlamp lens is one of the following:
    • SAE
    • VOR or SAE
    • VOL or SAE
  1. Once the headlamp beam pattern is identified, aim the headlamps using one of the following methods as applicable.
    • Photometric aimers can aim SAE, VOR and VOL type headlamps. This is the preferred method of headlamp aiming.
    • Visual or screen method aiming can be used to aim SAE, VOR and VOL type headlamps.
    • Mechanical aimers can be used only with SAE type headlamps. Lamps that can be aimed mechanically will have three nibs molded into the lens of the lamp.
Photometric Aiming
  1. For the photometric aiming procedure, refer to the appropriate photometric headlamp aimer instruction manual.
Screen Method Aiming
All headlamp types
NOTE: Horizontal aim is not necessary for VOR or VOL headlamps.
NOTE: Consult your state vehicle inspection manual for recommended tolerance ranges for visual aiming.
NOTE: The sight shield may need to be positioned or removed for access to the adjusters.
  1. Before starting headlamp adjustment:
    • Check the tire inflation.
    • Check that no other load is in the vehicle other than a half tank of fuel.
    • Check that the headlamps are clean.
    • Check for correct headlamp operation.
    • Check that the vehicle is on level ground.
    • If the vehicle is equipped with air suspension, make sure that the switch is on.

How do you adjust the headlights on a 2006 dodge ram 2500 ?


The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.
