SOURCE: Driver side door switches are not working. Dome

My power locks, windows didn't work and the dome lights would not turn off after closing the door. I removed the black boot that was attached to the drivers door by lifting upward and pulling away from the door. A heavy gauge black wire was broken. I removed about 3/16" of insulation from both ends of the broken wire and connected them by using a connector that both ends are placed in to and then "crimped" both ends so the broken wire made contact with each other and everything worked perfectly! The hardest part was replacing the boot. Total cost to fix is $0.50.

SOURCE: 2007 Buick Lacrosse low beam headlights both went

The relay under the hood may have gone out. We had the same problem on our 2007 Buick LaCrosse CX. The bulbs were fine, high beams worked, all turn signals and everything except the low beams turned on. Turns out the relay had gone bad.

2011 Buick lacrosse replaced battery car started then died after 15sec. No pwr checked all fuses-relays-cables-key stuck in column can't unlock to move cars. any ideas dealer no help.


Since you have no power to the ignition switch( you can't get the key out). Look to the main fuses first. You can see them threw the top. If the solder joint isn't shiny, pull them first. Since it did start and run, it isn't the ignition switch. Wiring most likely in place. Fuse panel could be bad. I've replaced a lot of them. But not with out diagnostics.

2011 buick lacrosse door lock does not work on drivers door only.


There could be many problems in this situation. Here is a list of some things to check:

1.) Check the wire connection in the door jamb where the wires transfer from the vehicle to the door. Sometimes these connections get a little off and things start acting goofy because the door being open and closed all the time(nothings perfectly designed).

2.) Check the relays in the fuse box, I can't remember if on this model vehicle if they used separate relays for each door or just one for all of them, but the relay could be bad.

3.) Check the locking mechanism inside the door by taking off the door panel and using a multi-meter and a 9 volt battery. I've checked the locking mechanism inside doors with a 9 volt battery before to make sure the mechanism was able to do it's job without being hooked up to the vehicle's power source

Remote often fails to unlock the doors on my 2006 Buick Lacrosse. Seems to work better from farther away.


  • I HAVE HAD SIMILAR ISSUES WITH THE KEY FOB, OR "REMOTE" . UPON FURTHER INVESTIGATION, I OPENED UP THE REMOTE AND FOUND THAT THE THIN, SHINY METAL FRAME ENCLOSING AND CRADLING THE COIN-LIKE BATTERY (CR2025) HAD BEEN SEPARATED FROM THE SOLDER POINTS ON THE SILICON CHIP.

  • I ALSO DISCOVERED THAT ON THE REVERSE SIDE OF THE CHIP (BUTTONS AND RUBBER COVERING SIDE) THAT THERE WAS DIRT, DEBRIS, AND OTHER GUNK WHICH WILL DEFINITELY SHORT CIRCUIT, CAUSING YOUR REMOTE'S BATTERY TO BE DISCHARGED OR MISFIRE. THIS IS BEST OBSERVED WHEN YOU EXPERIENCE A "STICKY" BUTTON EFFECT ONCE THE "LOCK" BUTTON IS DEPRESSED ONCE, BUT THE CAR FEED BACK SUGGESTS 2 PUSHES OF THE REMOTE WERE DETECTED. ANOTHER EXAMPLE: I COULD HAVE SWORN I PUSHED "UNLOCK" TWICE (UNLOCKING REAR DOORS )ON THE FOB/REMOTE BUT ONCE I GET TO THE CAR, DOOR IS STILL LOCKED! WTF.

SOLUTION:

KEEP KEY FOB / REMOTE CLEAN, REPAIR/REPLACE BROKEN BATTERY +/- CONNECTIONS IN THE REMOTE, REPLACE LITHIUM BATTERY
