So I really need help with a stubborn power window on the passenger’s door of my ’02 LS430. Going down is fine but when you try to put it up it only goes a couple of inches before it stops. You have to wait several minutes before trying again and then it only goes a couple more inches before it stops. It may take up to 10 minutes to finally get it all the way closed. So far I have replaced the motor, the window regulator, and the door-mounted computer. While the window was out of the way I also used WD40 on the window tracks. Once everything was installed I tried the window and the same thing happened. There is a new twist to the new parts…if the window is in the fully closed position and you accidently hit the switch to check that the window is all the way up, it will drop down about 3 inches or so. I have checked the wiring for signs of a break or a fray but nothing. Also tried swapping out the switch from the front door to the back door and still no luck. All help or suggestions would be greatly appreciated.

Hi Howard and glad your here. You should have no problems with replacing the rear-deck sub. The problem probably is the material around the upper frame that vibrates with the rest of the cone. They just get old and brittle and either tear or pull away from the mount. If it is a small tear it can some times be repaired with glue/ adhesive. Look this repair up in the data base. There are some post with photos. I don't know what impedance the speakers were in 2001. My guess is 4 ohms. With Lexus, it is important that the installer makes sure the speaker matches the cross-over network. This speaker is a mess to get out. You can't remove it from the trunk. The back rest of the rear seat has to come out then the package shelf must either be taken off or sometime just pried up enough to pull the speaker out. Since this tends to be a common problem on earlier models I would suggest doing a search of our data base for information on other members experience. I don't know from experiance, but there may be a video on "You Tube" Let us know how it goes. Paul

There is no dipstick for the AT. The AT is so called "lifetime lubricated". Adding or draining fluid to AT is done from below, a royal pain too......
