The 2006 Buick Lucerne with a 4.6L engine does not have a traditional serviceable fuel filter that is easily accessible and replaceable like some older vehicles. Instead, the fuel filter is integrated into the fuel sender assembly, which is located inside the fuel tank. This design is common in many modern vehicles, where the fuel filter is not intended for routine maintenance and is expected to last the life of the vehicle.
If you suspect a fuel system issue or a clogged fuel filter, it's recommended to consult your vehicle's service manual or contact a Buick dealership for guidance. In some cases, if there are symptoms of fuel system problems, such as poor performance or hesitation, it may be necessary to perform a diagnostic scan using specialized tools to identify and address the issue.
If you are not experienced with working on fuel systems or if you are uncertain about the location and replacement procedure of the fuel filter in your Buick Lucerne, it's advisable to seek professional assistance. A qualified mechanic or Buick service technician can provide accurate information and perform any necessary repairs or diagnostics.
Here's what you can try to open the hatch of your 2004 Buick Rendezvous:
Open the hatch and slip a screwdriver's shaft into the opening of the latch (simulating that the latch has engaged the metal bar on the floor of the SUV).
Apply pressure in the latch via the shaft of the screwdriver. While pulling against the latch, operate the unlock button of the fob or unlock with the key (whichever your truck has) .
If this doesn't work, you may want to consider taking your car to a professional mechanic or a Buick dealership for further assistance. But here is video on how to remove a window, if that servers any help. Door Window Removal And Installation Buick Rendezvous (youtube.com)
DTC P0455: Evaporative Emission (EVAP) System Large Leak
Circuit/System Description
The powertrain control module (PCM) tests the evaporative emission (EVAP) system for a large leak. The PCM monitors the fuel tank pressure (FTP) sensor signal to determine the EVAP system vacuum level. When the conditions for running are met, the PCM commands the EVAP canister purge solenoid valve OPEN and the EVAP vent solenoid valve CLOSED . This allows engine vacuum to enter the EVAP system. At a calibrated time, or vacuum level, the PCM commands the EVAP canister purge solenoid valve closed, sealing the system, and monitors the FTP sensor input in order to determine the EVAP system vacuum level. The following table illustrates the relationship between the ON and OFF states, and the OPEN or CLOSED states of the EVAP canister purge and vent solenoid valves.
The red X by the 02 sensor on your scan tool has nothing to do with.
You had the gas cap and the purge valve replaced, how about the vent valve under the back of the car. These go bad, cause large leaks. Also check the fuel fill tube,they like to rust out causing large leaks. If all that is good you may won't to it to a repair shop an have it smoke tested.
The thermostat on a 2004 Buick Rainier is located under the housing that connects the large radiator hose to the engine block. You will need to remove the cap that is held on with 2 or 3 bolts to access itI think this is on the passenger side but some diagrams have it on the other side.
Try taking the belt off and starting the engine. If it is something in the accesory system, the whine will go away without the belt. If it is still there you know it is something in the engine. If it does go away you can then spin and feel the bearings in the tensioner and idler puleys to find the source of your noise.

The only way to find is first jack up each wheel and spin it. Look at the back of the tyre and the wheel. Also look for fallen wheel well guards. It can even be a stick picked up after driving through a puddle!

STOP/ TRN fuse #12 20amp, location - in the instrument panel fuse box. Is this the one? Fuse blows because you have a short circuit on the wiring that fuse protects. Do you know what that is?
Turn Signal Lamps
The STOP/TURN fuse in the instrument panel (I/P) fuse block supplies battery positive voltage to the body control module (BCM) for the turn signal lamps. When the turn switch is placed in the left or right position, ground is applied to the BCM on the left or right turn signal switch signal circuit. The BCM then applies voltage to the appropriate front and rear supply voltage circuits.
Grounds for the various lamps are as follows:
• G100 supplies the right front lamps
• G101 supplies the left front lamps
• G400 supplies the right rear lamps
• G401 supplies the left rear lamps

I would take it to a Body Shop as they will be experienced in removing seats.
Likely to be the worm drive that moves the seat on the track. May just need adjustment and grease.

Question edited for clarity.
Question moved to model category.
Why do you want to 'reset' it? You can do a simple reset by disconnecting the battery for an hour, but then you also have to put the code back into the radio and also reprogram the anti-theft system and engine immobilizer.
Better to contact an auto electrician who will be able to diagnose your issues with a professional grade scan tool computer.
