Hey Guys,

My front door lock power locks stopped working so I took the actuator out of the driver's side and opened up the Yushin made mechanism. Looks like the tiny 12v motor isn't working. It reacts sometimes and sometimes not and gets very hot.

It's easy to get to it once you have the entire actuator is out but I'm having a hard time finding the motors on Ebay or Amazon.

Part # is 1020316 3H0608 B6782. Anybody have any idea where I could find these?

Look like this.

Thats what I'm trying to avoid. $150 per side or $7 for a 12v electric motor.

I'll let ya know if I find a matching motor.

This kia Sedona motor is very similar in all measurements.

I got $6 motor from eBay and it worked. I'll upload pics. It's easy to swap the motor

Annoying part is detaching the door handle from the mechanism and finding the tab to release the inner door never from the door.
 
Bad news. So I found 3 pairs of generic 12V motors on Ebay that fit perfectly, but they all spun in the wrong direction. One pair had the + and _ connections at the wrong end. When tested with 12v source they all spun opposite to the OEM motor. So when I tried one of them it would lock the door when I disarmed the car and unlock when I armed the car.

Jameco and AllCorp don't sell this motor and the manufacturer, Johnson, doesn't have them listed any longer or doesn't want to sell them to the public.

If it wasn't a circuit board type wiring, I would have just reversed the wiring but that is tough in that little enclosure. If you're very good at soldering you might be able to pull it off. I couldn't do it and make it seem like a safe solder.

If you can find motors that spin the correct direction, you'll save a ton of loot.

These are the circuits you need to reverse by cutting and crossing somewhere before the area prongs are in which plug into the motor.

This kia Sedona motor fit as well but the screw is reversed and it spins the opposite direction.
 
Great knowledge for our long term maintenance!
Thanks to all for the information.
Small unobtainable, parts are becoming the norm for any long term owner maintenance, especially stuff specific to our models.
 
Its terrible to have to throw away a perfectly good unit over this $2 motor.

I don't know anything about DC motors, but I read that with low voltage permanent magnet DC motors you can only change the direction of the shaft by reversing the polarity.

Ill post some tips for getting the locks out....a few pics will help the next guy a lot.
