2003 buick lesabre wont start!

So i replaced the left low beam bulb in my moms 2003 buick lesabre, and now it wont start. I replaced the bulb with the same part number except the wattage was 55 instead of 51, i didnt think this would be much of a problem other than it might draw more electrical power to run the bulb which could in worse case seniro blow something earlier in the circuit. the battery reads around 4-6volts connected in the car, but when i pull it out and test it reads 12? Something is drianing the power before the starter... I do not know this car at all. Could it be a relay somewhere? Is there something on the buick lesabre that is notorious for breaking? Any help would be great. Thanks and sorry about the spelling and gramar.

You should be able to get to it by removing the headlight

  1. Remove the headlamp fasteners.
  2. Using a pry bar, gently pry in the center area of the headlamp assembly. Pry the headlamp assembly straight forward in order to unsnap the headlamp ball stud from the ball stud socket.
  3. Slide the headlamp straight forward and disconnect the headlamp electrical connectors from the forward lamp wiring harness.
  4. Remove the headlamp from the vehicle.

SOURCE: broken steering collumn 95 buick lesabre

Okay well here is your most likely problem,the nuetral safety switch it's located on the transaxle(transmission where the shift linkage comes in)you can test this to make sure its working but it will require conituity tester,a parts store might also test it for free,this is a $100+ dollar switch,so if needs to be replaced check with the local salvage yards to see if you can get one used.0ccdc81.gif

The low beams on my 2006 buick lacrosse wont work the bulbs and fuses have been replaced but they still wont work

Shannon, you did not state if you checked for voltage at the fuse location-or better yet at the bulb location-
If a connection at the relay that feeds power to the low beams has come loose, then the low beams will stay out. Suggest that you locate the headlight relay (in a box under the hood) and verify that it is operating. If an assistant can operate the headlights while you listen (and feel) for relay operation, then you can eliminate that as an issue. Next would be the output of the relay (contacts could be bad) - and if you cannot open the relay to verify good contacts, then purchase a replacement relay (possibly from a junkyard) and plug that in.

Remember, the relay supplies the power to the headlights.

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

1988 buick century headlights

To change the low beam headlight on the 2001 Lesabre, the headlight assembly must first be removed from the car. It is really quite simple to do. There are two bolts on the top of the assembly that must be removed - that is all! The entire assembly comes out and gives easy access to the low beam bulb. Give it a 1/4 counterclockwise turn to remove it. Plus in the new one (#9006) and reverse the procedure.

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,
