I want to do this so starting to get the parts together. I got 2 motors for $80 each on ebay. It will take some time to get materials together, but I would like to test these motors. What is the easiest way to do that?

Connect the wires to 12v and ground. The motor will operate to the limit, then stop. Flip the 1v and ground and the motor will run in the opposite direction, hit its limit then stop.

I have two LC switches if you need them.
 
Working on this for my rig at the moment. Have the wiring worked out w/ the Sienna switch (will post pics once it's installed, but used this diagram and
bench-tested it and it's working).

My only question is does anyone know the polarity of the illumination pins for the Sienna switch?
Tried both polarities w/ 12v on pins 1 and 5 and neither way lights up.
Not sure if the led in the switch is dead or I potentially blew it by guessing the wrong way first time, but any advice from someone w/ a lit up Sienna switch would be appreciated.

I don't have my sienna switch anymore, but I believe it used the regular bulb (the switch housing has a little round plastic cover on the side -- unscrew to replace the bulb)... so, not polarized and would work either way. Bulb may be burned out. Could try an ohm (resistance) test on those two illum pins if you have a multimeter. Shouldn't be low (shorted) and shouldn't be open -- maybe a several hundred ish ohms.

Ah, I was wondering what that little cover was! Yeah the bulb is open by my multimeter. You wouldn't happen to have the part number for that?
Looking rn, but have to find the diagrams for a sienna.
 
Can anyone explain the basics to me.

1. How does the normal vent window switch activity work in a sienna or a LC?
To open, do you press once and release and the motor shuts off when the window opens or do you hold the switch until the vent window opens and you hear the motor stop, then release the switch? Then to close the windows, follow the same process...long hold or press and release?

2. Is this motor either fully open or fully closed or does the length of the switch hold determine how open the window can be?

3. When adding the motors to a gx470 and using the Sienna switches, if someone wants to use 2 switches, one for each window, what is needed? 2 motors, 2 sienna switches and 2 relays? And again, is the normal process to press the button once and release or to long-hold the button?

If someone has two Sienna switches and wants to hook them up in front for individual control of each window from the front but still wants one switch in the back by the rear gate to control both vent windows, is this possible or if you have two switches up front you then must have two in the rear?

Thank you for explaining this process.
 
Based on my experience with LC motors/switch:

1. Hold until the window is open or closed.
2. No, the window can be open partially if you don't press the button long enough.
3. 2 switches, 4 relays, 2 motors. Same.
 
Those motors just aren’t found cheap anymore. I finally ordered a pair from a salvage yard in Mississippi for $150/shipped. Got the Sienna switch w/ plug and wires long enough to splice if needed for $10 plus my shipping label from a place in Kentucky.
 
I was able to grab one motor and a sienna switch out of a pick and pull for $8, was really bummed the other motor was damaged. I think that’s the only way to do it cheap.
 
Closest pick and pull type place to me is a 2.5-3 hour drive one way. That leaves me with he internet if the few local yards don’t have what I want.

Way back in the 80’s I scored so much cool stuff. One yard did a special one day promo where you paid $50 for whatever you carried out.

They were shocked seeing me staggering out with:
Complete Mopar 8.75 rear axle over my left shoulder.
Cast iron 4 speed trans/shifter hanging from my right hand.
Bell housing, flywheel, driveshaft and trans tunnel hump strapped to me with old seat belts.
Threw bolts and small parts in my pockets and mason bag with my tools.🤣🤣

Gotta see if that old pic is still floating around somewhere. Good times.
