shaka_zulu Posted May 23, 2003 Share Posted May 23, 2003 Hi, my lexus es300's power windows do not work. When I got the car the seller or someone else apparently installed a bigger fuse than what it's suppose to be. So a lexus mechanic told me that the wring for the PW and PL are burnt inside the dash. They are looking for $1500 for repair, most of it is labor. Is there a way, I can make this into a weekend deal and change out the wiring myself by following the schematic or is it tricky? Plus is there a place where I can get the schematic from? THanks Quote Link to comment Share on other sites More sharing options...

92ES300 Posted May 23, 2003 Share Posted May 23, 2003 Yeah, I am having the same problem, my driver side front power window has stopped working. The motor was going rel slow, and then stop working totally. I have a 1992, and I really want to do everything myself, including buying and replacing the motor, or whatever needs to be fixed. Someone said it might be the hands on the motor, but I think I will just replace the whole motor. So far, I know the screw for the door in in the handle on the door, but I do not know of any other screws or how to take the door off. I took the door panels off my 90 Mercury Cougar, but I am sure a Lexus will be much more complicated. It is getting annoying for me to have to open my door or use the driver side rear window for drive throughs... Quote Link to comment Share on other sites More sharing options...
SKperformance Posted May 23, 2003 Share Posted May 23, 2003 92es i think your problem is with the window switch itself not the motor it goes one way fine but was slow the other way it is easy to ope the door one screw is under the little felt patch for closing the door one more under the tweeter halfway in the doorhas a plastic cover the rest are plastic clips and plugs to be pulled out the switch itself has very small plastic pins that break i did this in 2 of my windows don't go down easy but up is fine 3 ways to fix buy a new master switch set 250 fix the broken internals of the switch of get a donor one and relace parts this includes using one of the rear door ones as you will still be able to open there window just they wont tell them the safety is on Quote Link to comment Share on other sites More sharing options...
92ES300 Posted May 24, 2003 Share Posted May 24, 2003 Sk- So if I replace the motor, it won't do anything? What is the cheapest thing I can do, and how do I do it? Also, the window goes down fine, but it has trouble going up, if it goes up at all. Thanks Quote Link to comment Share on other sites More sharing options...
SKperformance Posted May 25, 2003 Share Posted May 25, 2003 well i can't say for sure if there is a problem with the motor but take the switch out open it up and look at the under side of the switch it has 2 plastic pieces that stick into the switch see if that is what is broken it is free to look and easy to put back to gethr in my opinion only a little spring and maybe a balll for the most trouble takes about 30 minutes to get it out of the door and opened up Quote Link to comment Share on other sites More sharing options...
steviej Posted May 25, 2003 Share Posted May 25, 2003 i'm putting money on that it is the motor. The switch is ON or OFF. Current to the motor or no current to the motor. Not slow current to the motor so the motor runs slow. If the motor moves at all, then current is passing thought the switch, so the switch contacts must be making contact. I say the brushes in the electical motor are worn out so good contact cannot be, thus limiting the motion of the window due to poor performance of the motor under load conditions. I'm going on past experience with window motors, current experience with electical motors (not just window) and gut instict. just my $0.02 steviej Quote Link to comment Share on other sites More sharing options...
SKperformance Posted May 25, 2003 Share Posted May 25, 2003 that is exactly what i thought stevie as all things being equal and common knowledge it mad eno sense at all until i started playing with the switch and pushing it lightly then when i opend mine up i saw the pin broke but occasionally would fall into the perfect position so when pressed it activeted the switch but do the easy thing and trace the wiring give the motor direct power and see or just open the switch at the same time later mine was easier to trace as the rear driver one wasn;t working on the master but worked fine from that door the drivers one only has one switch Quote Link to comment Share on other sites More sharing options...
gslx4s Posted May 25, 2003 Share Posted May 25, 2003 "Is there a place where I can get the schematic from?" Any Lexus dealership parts desk should be able to offer you a copy of the schematic right out of the tech manual. You may wan to try that.
