Roger:
Ive read and re-read your window site....1) i cant seem to determine where to put power on the window regulator itself to test the unit as a whole and 2) everything i tried from there, didn't help. Replaced thermostat twice, and one of the temp switches below it, the one with the yellow male end. And for the TPS, iv'e tried adjusting it several times, but dont really understand your site, so i did it to the best of my ability..it appears to be in correct position.
The rear window relay module basically puts 12V across the rear window motor, if one side gets 12V and the other side ground, motor turns one way, swap the power and ground leads and it turn the other way, so you would apply power directly to the motor to bypass all the interlocks. Best to follow the troubleshooting steps as outlined on my page, they are roughly in the order of easy to hard to test things and also check the oh-so-common problems of the missing shell interlock bolt and the rear window wiper that is not fully retracted. Those two problems cause probably 95% of all rear window problems.
What temp. and brand t-stat are you using? I find only the real
Toyota brand t-stats work reliably over the long run. What is causing you difficulties on adjusting the TPS? Maybe I can clarify the directions, and have you checked out the really simple step-by-step hints Frankenyota added:
Step by step times for adjusting the idle setting Basically you want to test the unit to see if the overall readings are within spec., that is do you get a resistance that is proportional to throttle position? You do this with an ohm meter and just check the resistance readings between terminals as noted.
If all the basic readings are OK, then you need to adjust the IDLE sensing part so make the TPS detect a closed throttle. You do this by loosening the TPS itself and rotating it on the throttle body until it reads the correct IDLE setting on the meter.
