Head Lamps ON my 2000 Buick LeSabre quit working - Brites only work IF I hold Lever in , ALL other Lites work. ALL Fuses n Relays good Should I replace Lamp switch ?


Hi Ricky, Im AL the owner of Big As Auto Repair.

Ricky, if the high beams work when you hold the lever in, then its the high beam switch NOT the light switch. The lever controls the high and low beams. You need the multi-function switch which is also the dimmer switch. Hope this helps and please visit my auto-repair-website at: http://www.bigasautorepair.com/

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.

Need to replace drivers side low beam light. I see two bolts than when removed should release lamp module. But, it is not feels like there is a third I'm not seeing. Is this the case? How ho I remove the...


The bulbs in your car are replace from the back side. They are sealed units. The bulb will come as low and high beam built in one bulb. Go to an auto parts store and get the bulb first so you can see what you are looking for, there is a ring that holds the bulbs in the assembly. The ring will turn about a quarter turn and unlocked the bulb will then pull out from the rear and you can replace it. Hope this helps you out. Roger

REPLACEMENT OF [LOW BEAM] HALOGEN BULB IN 2004 Buick LeSabre


I just Replaced a Low Beam Light bulb on a 2005 Buick La Sabre.

If You use a Metric socket and Remove the Two Silver bolts Attaching the headlight Assemble onto the metal surrounding the the lamp assembly it comes out to the front. This makes it much easier to access the bulb. Twist it counerclockwise & it comes out by pulling gently on the bulb. Then by realeasing a tab that is the socket holder bulb can be removed & replaced with a New #9006 low beam halogen light bulb. Wrap a Paper towel around the bulb & do NOT touch it with your bare hand as this wiil ruin a halogen bulb,

Right headlamp


Check the fuse for the passenger side.It is under the hood. it may not be making good contact. wiggle it a little bit and see if it makes any difference. if not, check where the the ground wires are connected to the chasis. See if thats not the problem.

2002 Buick LeSabre Limited RH Headlamp assy


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.
