This should be a normal threaded cap and will twist off in a counter clock wise motion. If the cap is not original and has been replaced with a locking type cap, it will require a key to unlock it and the removal procedure will be the same as the original cap

the fuel "hatch" has a press and release catch, press the rearmost part of the hatch then release once it clicks, this will allow you to gain access to the fuelling cap. the cap can be removed by just unscrewing it counter clockwise posting link, directions on opening are on section 9 page 50 https://www.buick.com/content/dam/Buick/north_america/usa/nscwebsite/en/home/owners/vehicle_manuals/2013/02_pdf/2013_lacrosse_manual_2nd_printing_20121029.pdf

Take your Rainier out for a drive and see if the cruise control still works. If it does, the VSS is likely fine. If not, the VSS could be the culprit (Vehicle Speed Sensor). Cruise control also depends on throttle position. Ensure that the throttle body and related components are functioning properly. Examine the wiring going to and from the VSS. Look for any damaged or frayed wires. The most common reasons for cruise control malfunction are failed control modules, faulty sensors, or switch issues. While you've already replaced the brake switch module, it's essential to verify that it's functioning correctly. Additionally, check other control modules related to the cruise control system. While you've already replaced the brake switch module, there might be a separate cruise control module. Inspect this module for any signs of malfunction. Powertrain Control Module (PCM): The PCM monitors the signal circuits of the cruise control switches to determine when to capture and maintain the selected vehicle speed. It uses the throttle actuator control (TAC) module motor to control the vehicle speed. That would be something to check. Visually check cable connections and for corrosion. A multimeter can check the battery which can affect the PCM. Sometimes, disconnecting the battery to clear any fault codes can resolve cruise control issues. Possibly that might work even though you see no fault codes.

Have you checked your amplifier?

Might have a bad actuator, which open the access port for warm coolant to enter the heater core.

Question edited to add Translation. We only speak English on this North American website. https://translate.google.ca/ Page 105. Make sure they are turned on at the dimmer. https://www.dezosmanuals.com/wp-content/uploads/2021/07/1994-Buick-Regal.pdf ..

This seems to to be an issue with some Buicks. I don't think Buick have a specific fuse for the back up lights and the 2005 to 2007 Rendezvous models had a relay for those lights. OK. Start with the simple and silly stuff first. Check the bulbs and the sockets they fit into. It could be a blown bulb or there is dirt and corrosion on the contacts blocking the electrical current to the bulb. Using a multimeter set to DC volts test the bulb socket for power to the bulb. With the Park brake ON, the Ignition ON and the Engine OFF selecting reverse should turn the back up lights on to test for power. If no power to the light fitting next move to the switch on the Transmission the shifter operates when you select reverse. I'm not sure where it is on the Rendezvous Transmission, You might get lucky and it'll be screwed into the housing next to the actual shifter.

have a shop check it out scan it did battery (main) just fail ? and then recovered.. if yes, that is auto learn doing its job. if not , then scan it.

P1811 is for maximum shift adaptation and long shift detected. The possible causes are long - clogged transmission filter cut seal on transmission filter low or burnt fluid 1-2 accumulator faulty 2-3 accumulator faulty 3-4 accumulator faulty valve body spacer plate damaged pressure regulating solenoid damaged pressure regulating valve damaged fluid pump faulty restriction in hydraulics of transmission 1,2 or 3 clutch damaged forward band burned or broken torque converter clutch broken The first step is to check line pressures with scan tool and transmission pressure gage, then with scan tool test the pressure solenoid. If pressures are low and pressure solenoid test good, then transmission is pulled and torn down to inspect and repair as needed, which is usually a complete rebuild in this case.

The float arm inside the tank is sticking. You would need to remove it, make sure it is free and perhaps bend it left or right a bit, but not up or down as that will change the level reading. https://www.google.com/search?q=1999+Buick+Regal+LS.+Gas+gauge+is+stuck ..

A 2004 Buick LeSabre uses refrigerant called R134a. The amount of refrigerant needed should be noted under the hood, but may not be. Whenever the refrigerant is recharged, a specific amount of PAG 46 oil will also need to be used, to lubricate the compressor.

Okay, for starters you're going to need a Phillips screwdriver, now you have to put each wire on the right terminal.First identify the proper orientation of the cap, it only goes one way, look for the tag on the cap that must fit into the notch in the housing align the old and the new caps remove the wires one by one from the old cap to the new cap then use the screwdriver to turn each of the four retaining lugs you must push down the screwdriver and turn them CCW about a quarter to a half turn the app should come off the rotor is there underneath remove the two screws and install the new rotor it only goes one way. Put the cap on making sure it fits into the notch. The lugs should go back in easily if the cap is on right way, if not you would have to feel for it. Good luck..... ????
