I took some measurements while the window lift motors were operating out of the vehicle but the results were inconclusive. The old motor and the new motor both drew about the same amps, but the old motor could not wind the regulator all the way up (which is the down direction) against the spring tension of the regulator.

What we need is a test fixture where the output torque of window lift motors could be measured.
Has anyone bypassed the switch and run heavy gauge wire straight from the battery to the window motor to see if that helps? Other Toyotas have been known for needing upgraded wiring in certain areas, maybe this is one area that needs it.
