Hi Guys. I have a 1990 Acura Legend. The front driver's window stays up. We hooked power to the window and it does work (comes up and down in track). Then the other front window stopped working. (Going backwards here!) I replaced the black plastic controller regulator attached to inner door panel. No difference. I switched out the relays in the black plastic fuse box top of engine, driver's side. I replaced the power window switch (put on a 1990 door panel from wrecking yard with different switches) no difference. The only weird thing is that when I operate the rear windows (which always have worked fine) the regulator/controller is completely silent but when I attempt to operate the switch for the driver's side window the controller/regular CLICKS inside.

Gee Whiz!!!!

What should I try next? Thanks in advance for your help.

Sounds like the regulator itself. Assuming your telling me the switch on door panel has been changed and the window motor is confirmed operational. . If two widows are the problem , in a 1990 it is likely the regulators are gettin worn. Useally the drivers window first then front passenger the the rear due to extent of use.
