Clean the frame thoroughly, apply new adhesive, and position the new windshield into place, ensuring a proper seal. Finally, reattach the trim and wipers, allowing the adhesive to cure as per the manufacturer's instructions.

To replace the oxygen sensor (sensor 1, bank 1) on a Lexus SC 300, first, ensure the engine is cool and disconnect the negative battery terminal. Locate the sensor, typically found on the exhaust manifold or upstream of the catalytic converter, and unplug the electrical connector. Use an O2 sensor socket or wrench to carefully unscrew the old sensor, then install the new sensor by threading it in and tightening it securely. Finally, reconnect the electrical connector and the battery terminal before starting the vehicle to check for proper operation.

To remove the rear view mirror from a Lexus SC, start by locating the mounting bracket that holds the mirror in place. Typically, there will be a small set screw on the underside of the bracket; use an appropriate screwdriver to loosen it. Once the screw is loosened, carefully slide the mirror off the mounting bracket. If needed, you may also need to disconnect any wiring for features like auto-dimming or Homelink before completely removing the mirror.

To start your Lexus SC300 after replacing the battery and encountering issues with the alarm system, first ensure that the new battery is properly connected. Then, use your remote key fob to unlock the doors and disarm the alarm. If that doesn't work, try inserting the key into the ignition and turning it to the "on" position without starting the engine for about 10 seconds to reset the alarm. If the alarm still won't disengage, you may need to consult the owner's manual or contact a dealership for assistance.

To disable the anti-theft system in a Lexus SC300, you can try using the key fob to unlock the doors, as this often deactivates the system. If that doesn't work, insert the key into the ignition and turn it to the "On" position without starting the engine, then back to "Off" five times in quick succession to reset the system. If these methods fail, consult the owner's manual or a professional for assistance, as tampering with the system can lead to unintended issues.

The fuel pressure regulator on a 1992 Lexus SC 400 is located on the fuel rail, which is situated on the engine's intake manifold. It is typically mounted directly on the fuel rail itself, near the injectors. To access it, you may need to remove some engine covers or components for better visibility and working space.

To reset the remote key on a Lexus SC 430, first ensure that you are inside the vehicle with all doors closed. Insert the key into the ignition and turn it to the "On" position without starting the engine, then press and hold the "Lock" button on the remote for about 1-2 seconds.

On the Lexus SC 300, the oxygen sensors are typically located in the exhaust system. There are usually two types: the upstream (pre-catalytic converter) O2 sensor, which is found before the catalytic converter, and the downstream (post-catalytic converter) O2 sensor, located after it. Depending on the specific model year, these sensors can be found on both sides of the exhaust system, near the engine and the catalytic converter.

To fix a dim instrument cluster and non-functioning indicators on a 1993 Lexus SC 400, start by checking the fuse related to the dashboard lights, as a blown fuse could be the culprit. If the fuse is intact, inspect the dimmer switch for proper operation, as it may be malfunctioning. Additionally, consider replacing the bulbs behind the instrument cluster if they are burnt out. If these steps do not resolve the issue, it may be necessary to examine the wiring or the cluster itself for further electrical problems.

If your SC400 is lagging when you accelerate, it could be due to several issues, such as a clogged fuel filter, a failing fuel pump, or a dirty air filter that restricts airflow. Additionally, problems with the ignition system, such as worn spark plugs or ignition coils, can also cause hesitation during acceleration. It's advisable to check the engine codes for any diagnostic trouble codes (DTCs) and inspect these components to diagnose the issue accurately. Regular maintenance can help prevent such performance problems.
