Have you tried the "valet switch" in the glove box? This switch is used when you don't want a service person in your glove box OR your trunk - only the physical key will open the trunk or glove box. The trunk opener switch under the dash won't work either if the "valet switch" is activated.
The switch is located at the top of the glove box on my GS350 - yours may be different.

2008 Lexus IS250 AC low pressure charging port is located on the driver side close to brake booster. I accidentally saw it while changing the O2 sensor.

Cannot be replaced without replacing the assembly. Sorry. Club Lexis has a thread found here http://www.clublexus.com/forums/is-second-generation/625770-is250-license-plate-bulb-diy-or-new-housing.html

Changing vin by self is illegal if thats what your doing
If its door plates or firewall plates dealer has to order new and you have to take down to mvd and register numbers
If license plate unscrew it
But overall changing any of the cars factory registered plates is illegal without registering them threw proper channels first

I have on 07 is250 and the power windows and trunk release were not working. There is a trunk/valet button in the glove box that needed depressed in order to make them work again.

well the pictures are not in order but you can see what the cover looks like, the filter will be right under it .. there is two screws that are holding that cover in place.the picture above that is how it will look when you remove that cover.you will need a filter wrench to remove it..

it has electric power steering, take it to the dealer and ask if the service campaign has been done on the power steering rack. if not then it will be free and they will wash your car for you, fill up your gas tank and replace the steering rack and align the car. if it has been done then maybe they didnt reset the steering gear ecu.

My 2007 Lexus IS250 is dead, hooked up a charger. Charger keeps shutting off. Triple checked the cables, + - correct, still shuts off charger?

Try installing a K & N Air filter. Any good Parts store Carries them. Changed the HP and Milaeage on my 425 HP Chevrolet Truck. Added 35 to 45 HP and increased My Mileage to 23 Per Gallon!
