Question about 2000 Lexus RX 300
You have a bad ground wire somewhere; probably right off the drivers side door. It may be difficult to locate because all the window switches are wired to the master control switch on the driver side door. I often find the wire breaks somewhere in the conduit between the door and the dash. All the opening and closing of the door damages the wire, particularly when the wire doesn't have any room to flex. Once you find it and bypass the broken connection all the switches will work. Start with the connections on the switch and work your way to the dash. You probably can find a good YouTube video that can show you how it's done. A multimeter will be very useful checking the continuity of the wires. I like to disconnect the switches in both the driver and passenger doors. I will then use a piece of wire to bridge the connections on (passenger) door connector, or ground out to the vehicle body. You can use the multimeter probes on the driver side connector to find the broken connection without tracing the whole wire harness. There should only be one hot wire that is supplied with power on the drivers side connector. Use the multimeter to find the hot wire first, using the vehicle frame as the ground, and then ignore it. Once you find the color of the wire that's broken you can just follow it along the wire harness till you find the break.

SOURCE: Seat belt repair
first for the switch in window
the window switch is easy to test you just gotta remove switch out of the door leaving it hang there is a way to test with a guaged wire with fuse on it
take the main power wire and touch to the other connectors on the main switch if the window goes down or up the switch is the problem
im suggesting this way first with fuse cause its easier then testing the windows motor inside the door frame the switches should just pop out of the panel with out haveing to take panel off
now the seat belts there are 2 style that are common to chevy
one is inside the molding of the drivers panel you gotta pop off the panels easily and gently to get at the seat belt retractor this will be bolted to the metal under the molding
the other style is in the seat which you gotta unbolt the seat under the top half it will need to be unbolted at the bottom top half of seat
when you pull threw the top section of top half of seat remember to tie a string to the end so that when you pull threw top half the string will be there so you can connect too new belt and pull back threw with ease make the string long enough to hang
now the bottom half of seat what i call the "**** seat" you remove the molding at bottom around the belt retractor this will be bolted to floor bolt also pull belt threw molding once molding removed
disconnect any electric wires
now saftey issue involved with seat belt removal is for a reason i dont know of the dealer ship always discharges the belts and air bags once removed i guess because of static electricity becareful when you remove belt and replacing belts cause static elec. can set them off
once your seat belt is removed place in card board box and take to dealer after complition of installing new belt they will discharge your seat belt for you and then you can dispose of it properly

Hopefully by now you have resolved your problem but my truck had that problem and I had to replace the motor for the window controls.

The control may have gone bad... You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. Then you can disconnect the controls and test them

Did you ever solve this problem with your windows? My 03 Ion 2 is doing the same thing. We think it's a wiring issue. Any suggestions? Thanks, Kristen N!
