Hi,

I just picked up a 1995 SC400 with 66K original miles, white/ivory interior, no sunroof, Pioneer sound system, memory seats, steering wheel, and mirrors, and without TRAC or heated seats. Kind of a plain Jane SC400, except for the dealer installed gold Lexus 16 inch wheels, and gold badging.

Already fixed the Greyhound Bus tilt steering wheel so that it is now a normal car steering position, but am curious about how to fix the side mirrors not working, and the passenger window not working. I have read about the ECU that goes bad, and the Passenger window having a bad regulator and/or motor, but since they both are switched from the same control, how do I check the switches to make sure it is not the switch?

 

I had the same problem with the passenger side window. I experienced slow/no movement, and I replaced the regulator/cable mech. Dont try to repair the cable/regulator mech. Too many bad words said. Go on Amazon and order one and relax. My drive motor was kind of slow, so I applied wax to the guides for the window, and it runs great now.

 

Thanks for the kind reply. The first thing I did was to replace the regulator/motor with an EBay one, and it went up fine using passenger switch, but down, no such luck. Before installing, I tried running it both ways, and it did fine both ways. I ordered a driver side switch, and if that doesn't work, and I can't get my hands on a wiring diagram, I am going to have a shop look at it. There is a white wire with a stripe, forgot color that was a ground feed to passenger window switch that was not grounded. Maybe that is the problem, but I don't know where to locate the harness under the dash to jump a wire.

 

i have the power mirror ecu if you need it, it is usually the culprit for the side mirros not working. 65 shipped
