  1. Thanks for your reply.... i will try to trace this weekend.... i was hopeing for something easier to be the problem. So if fuse #12 controls the wipers and since the wipers work (which tells me the fuse is not burn), do you think i should start from the switch (lever) to the pump?
  2. Hello: The master switch for the RR window does not operate the window (i.e. window does not go up and down. All other windows work through the master switch. The RR switch works to bring the window down but not up? What is the link for the CD on ebay?
  3. Hello all: I have a problem with my 1990 LS400 which the RR window goes down but not up. Does anyone have schematics/wiring diagram for the Master Switch window and rear right window? If so, could you mail it to mad12.1964@gmail.com. Thanks in advance.
  4. Hello Bryan and others: Do you have the wiring diagram for 1990 LS400 Master Switch window and rear right window switch? thanks in advance
  5. Hello, I have 1990 LS400 and need your help. When I press on the windshield lever, the wipers move but the nozzles DO NOT spray the windshield washer fluid. The tank is full and I checked lines and they are not clogged. Took the windshield pump and applied 12v directly and I hear it working. Measured voltage from the wire connecting to the pump and I do not get any reading. Is there a fuse for the windshield pump? Any idea why no juice to wire connecting to the pump? Thanks for your help.
  6. I have a 1990 LS400 Lexus. The rear right window goes down but not up. I took the panel out and verified the switch is working fine (took the switch out and tested with the rear left window and worked fine.) I reconnected the “window switch” and disconnected the “motor switch” to measure the voltage. Turned the key to ON position and I pressed the “”window switch” down (to lower the window) in which the meter measured 12v. But when I pressed the “window switch” up (to bring the window up) the meter did not measure any voltage (which explains why the window does not go up). Any clue what could be the problem and how to fix it?

  8. I have 1990 LS400. I was trying to replace the right rear window regulator. I lowered the window (glass) to the bottom of the door. I can not seem to put back on track. What do I have to do?
