Power Window Failure


Recommended Posts

'93 SC 400...68K miles.

Hi guys...been gone for past 9 mos due to Ivan's wrath here in Pensacola. Good

to see some familar names still active.

My problem is with the passenger side power window. Yest I was in process

of rolling window up when I heard a sharp pop and the window stopped at

about 2/3 rds up. I then rolled it back down and that is where it still remains.

The motor runs but the window will not traverse. Two questions:

Could it have jumped track or is there a cable or maybe a plastic track that is

broken. I am not familar with the operating mechanism so I am just wondering

if there is an opinion as to what the problem might be.

Secondly...how difficult is it to remove the door panel so I might try to determine

the nature of the problem and maybe repair myself.

Thx for any response in advance,

I found this solution to repair of a failed power window and it sounds

very similar to my problem. Now, if I knew the trick to removing the

door panel w/o damaging it, I would investigate to determine the actual


Can anyone give me any guidance on passenger side door panel

removal ?

Same thing happened to my passenger door window.

Here’s what happened to mine:

There’s a rod shaped kinda’ like a “C” (the ends of the “C” point toward the back of the car) that connects the door latch to the inside of the exterior door handle. The end of the rod that connects to the handle has a grommet that Lexus calls a “Snap-link” holding it to the handle itself. The “Snap-link” deteriorated, broke, and allowed the rod to rotate so that it looked like a “U”. When I lowered the window, it got stuck in the bottom of the “U” but the motor kept pulling down and snapped the plastic part of the window regulator. There’s a guy who shows how to fix the regulator using JB Weld (sorry--I don’t remember where I saw the tutorial) but it looked like he had a lot of the plastic left. Mine was pretty wrecked—I just got a new regulator. Anyway…

Unfortunately, taking the door panel off is the easiest part of the job. The first thing to do is pop out the window/door lock switch assembly. Get a small screwdriver and cover the tip with tape so you don’t scratch the plastic or the upholstery. Then pry up the switch assembly from the end closest to the back of the car. Be careful because if you’re too rough you’ll break the plastic snap holding it in. Then unplug (I’m assuming you know how to operate the connectors so you don’t snap them) the connectors and set the assembly aside. Now take out the door screws; there are 2 screws covered by caps (use the taped screwdriver to get the caps off) on the left side closest to the door hinges, 3 or 4 along the bottom of the door panel, 2 that are underneath the door handle, and 1 under a cover behind the door-open lever(use the taped screwdriver to pop out the cover). When you’ve got them all out, pull the bottom of the door panel toward you (it should pop out relatively easily) and continue pulling the rest of the panel off going from bottom to top. The last thing to do is disconnect the door light connector and the cables that go to the door-open lever and door lock. The door should come free.
