SOURCE: heater core replacement

Actually if your handy the heater core on this car is pretty easy..  passengers side under the dash... but here is a link to some sites that will probably help  
from .... one of the wikki sites.. LOL cant remember which now

The heater core is located under the dash, in the center above the "hump". The container holding the core looks like a black plastic box. Remove the ash tray for easier access. You may have to also remove some other covers under the dash. First drain the radiator. Then you have to disconnect the hoses. There are two hoses connected to nipples of the heater core that are thru the center of the firewall. This has to be done from underneath the car while raised. I also had to unbolt a frame support to get to the hose clamps (I have big hands; you may be able to reach them without unbolting it). Remove the screws that hold on the cover to the heater core. You should be able to get the old one out now. Just go in reverse order to put it back together.

also this link is very handy they have a pretty complete collection for MANY vehicles

SOURCE: programing instructions for buick 2006 lacrossekeyless remote fob

Transmitter ProgrammingImportant: All transmitters which are to be recognized by the remote control door lock receiver (RCDLR) must be programmed in a single programming sequence. If the system is placed in program mode it will erase all previously programmed transmitters upon the receipt of the programming signal from the first transmitter. Up to 4 transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.

  1. Install a scan tool.
  2. Use the scan tool in order to access programming: Vehicle Control System/Computer Integrating System/Module Setup/BCM/Program Key Fobs.
  3. Press the START soft key on the scan tool. Important: The scan tool must stay connected until all of the transmitters are programmed.
  4. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of 5-10 seconds, the scan tool will indicate that the transmitter is programmed.
  5. Repeat the previous step in order to program up to 4 transmitters.
  6. Remove the scan tool.
  7. Operate the transmitter functions in order to verify correct system operation.
Good luck

SOURCE: change headlight 2006 Buick LaCrosse

The bright light fitting is the same as the dim so take it apart fist to see how the cover screws off/on and the light comes out. Both the cover and the bulb are removed by a standard twist to the counterclockwise and replaced by a twist to the clockwise. Now to the dim light. You have to release the entire light assembly before you can remove the screw-on cover to reach the light. On the rear edge of the light unit closest to the engine is a white locking tab. Pull that tab up just to the point where it releases…pull too far and it locks again. Next, locate the other locking bracket which is a metal bracket in the center-rear of the light assembly. This bracket is held down by a screw. Remove the screw with a 10mm wrench. Lift the bracket just like you did the white bracket. You should now be able to pull (or pry) the entire light unit forward a little. Depending on the size of your hands this might be enough. If not, then you need to release the plastic bumper assembly to give you a little more space. This is done by removing two expansion locking pins, one that holds the little plastic strip down between the bright and dim lights and one that is located inside a rubber bumper on the engine side of the light unit. To remove these locking pins, pull or pry up the little tab in the center of the pin just like you were pulling a nail by the head. That should give you more space.

Need more guide to remove heatercord on 2006 buick lacross

You sound like someone who is handy and wants to do the work him/herself. Unfortunately, the job you are undertaking is way too complex to explain here. There are many panels/screws/connectors to remove and replace. You need a written instruction guide with pictures to aid and assist. I recommend you get a Haynes manual at a local auto parts seller for your car. It will provide detailed instructions on what you are trying to do. It will also inform you if there are any steps that you cannot do, such as evacuating the refrigerant from the A/C system as is required to access the heater cores on some vehicles. Don't get yourself in over your head and find out you're stuck.

2006 buick lacrosse heater is not working

I strongly recommend you take it back to the dealer and ask for help.
If it is something they damaged, and you have another shop repair it, the dealer is then off the hook for responsibility.
The problem could be a blend door under the dash, or the heater core may not be getting proper coolant flow.

Heat guage shows normal temperature but heater throws cold air. Problem gets a bit better as engine is reved.

The heater core could be plugged up. Try to flush the heater core out, or replace the heater core in order to fix it. Also, check the heater core for hotness at two 1" diameter tubes at the firewall. If they're hot, then the blend door may be causing the problem.

Good luck on this repair.
