Temp gauge doesnt work, starts weird, and rattles when excelerating

Replace the temp sensor. When the ECM reads -40 degrees, yes it ups the RPM's and hard starting is because the ECM throws a lot of fuel to the engine. You may need to replace the spark plugs also, after the temp sensor.

When starting my 2007 buick lacrosse cxl, if I do not tap the gas petal a bit it will just turn over and then die most of the time. Especially when it's cold. My remote start doesn't work anymore because of it. I have also noticed that at times when I punch it while driving sometimes there is a hesitation like at first my head pedal is not working then it kicks in or catches ot whatever and then it goes. It has 220,000 on it. I'm not sure if the up keep before I got it. Could it be like the fuel filter maybe? Or o2 sensor maybe only the only light that comes on is for my thermostat that I believe is stuck open...

Ok it sounds as if you have a few possible causes check your key fob battery,then if you have not done so get your car scan to know what is going on with your car from what am understanding you can have a fuel pressure problem or a dirty throttle body because of the hesitation when you punch it but it can also be a fuel delivery problem
I hope this helps you

03 Buick regal Ls trunk lid taillights were working not long ago and all the sudden one at a time they started going out so they don't work along with the license plate lights, the bulbs are good and i have the outermost tail light / brake lights on both sides of the car so just the trunk lid cluster is out and the first thing I did Was check all my fuses They were all good and I double checked them to be safe with a test light also and they were still good and I also use the test light to check my sockets and there was power to them so I’m guessing it’s a ground but I don’t know where the ground connection points are...

Going out one at a time suggests bad connections of the bulbs to the center base in the sockets. The center contacts are spring loaded and over time they tend to stay compressed and lose connection with the bulbs. This is easy to check with your test light - when you checked for power at the sockets, did you ground the test light to the side of the sockets? If so and OK, check the condition of the socket and bulb end contacts for flatness and/or corrosion. If not, use a multimeter (resistance setting) to check the outside of the socket for resistance to exposed metal in the trunk - should be close to zero. If not, a loose ground connection in the trunk wiring harness may be the cause - you can find this connection (usually in the trunk) by tracing the wiring harness from a light back towards the front of the car.

2005 LaCrosse. Why does blower fan run constantly when the car is turned off?

No, that is a switching problem. Either a faulty switch or a glitch in the ECM from the battery being disconnected.

Where is the horn physically located on a 2011 Buick Regal

The horn assembly mounts behind the drivers headlamp. There are two horns made on a single bracket, a high and low horn, on most cars they are an A note and an F note. If you played these 2 notes together on a musical instrument you would hear that these 2 notes do not blend together, so together they make an annoying loud sound, perfect for an emergency horn. Some instructions state that you have to remove the bumper cover, others say that you can remove the drivers wheel plastic inner fender plastic shield. The bracket bolts to the core support. Hope that helps. You can find pictures of the horn assembly online. PS, I tried to upload a picture but it will not load. Hope that helps.
