WHAT COULD THE SOURCE OF THE ODOR IN MY 2007 LEXUS RX 350?

SOURCE: dashboard light

For Lexus the ! symbol usually is low tire pressure that's all there's sensors in each wheel that report to the car that the pressure is low, also if your wondering how much air to put in the tires you can look by opening up the driver or sometimes the passenger side door and look along the door there's a label that will tell you each tires recommended pressure. Any other questions just ask and id be glad to help you folks, and if you don't mind if you can rate my answer if you get a chance it would be greatly appreciated..

Thanks,
Steve

THERE ARE TWO FUSE BOXES ON THE CAR ONE UNDER THE DASH AND ONE UNDER THE HOOD. SHOULD BE ON THE RIGHT SIDE OF ENGINE COMPARTMENT WITH A COVER HELD ON WITH SCREWS OR LATCHES. ON THE INSIDE OF THE LID ON BOTH BOXES THERE SHOULD BE DIAGRAM OF LOCATIONS FOR THE FUSES

Testimonial: "Did not know about the one under the dash, is there a better explanation of what fuse or relay is for which? A pdf diagram maybe?"

open the glove box, grasp it firmly and pull straight up on one side and then the other. the box will unsnap from the hinge, once loose lower the box gently and let it hang from the tension cord. behind the box you will see a cover with release clips. remove the cover. pull the filter and tray straight out. be sure to replace the filter proper side up, it will be marked. reassemble.

it is located behind the glove box. the glove box has a compartment separator inside of it. you must pull up and out to remove it. the back of the glove box has a removable panel. remove it. the filter tray will have a cover over it with two snap clips or the fresh air circulator on the dash will have to be set to recirculate to open the cover for the filter.

Jim , you can change both the air and cabin air filters. There are a series off pop pins covering the air intake. If you depress the center button with a BIC pen tip and then lift at the side they will pop up. They are a plastic spring load so be gentle.
Underneath you will find the intake housing and filter. Cabin air filter should be behind the glove box area I
believe .
FYI , Lexus has a patented high volume oil filter. If you change your own , stcik with genuine for longer life, unless you are certain the aftermarket matches
