Where can I find one?

 

Rock Auto has rebuilt units but they are expensive at $276 plus core charge. Try ebay or see if a local recycle yard has an X300 (assuming thats what you have). You might find all 4 there for cheap. We don't hear about them failing very often.

You can take the one you have and run it up and down with a battery charger

Just flip wire connection ( polarity ) to run other way

This even works on car , just pull the 2 heavy wires out at the fwd of the door panel and clip

This will be high current so arcing hazard , the motor has resistance so not a direct short of the charger

Put the charger on 10 amp setting and not lower to run properly but you can use the lower than to practice the connection to be made

There is a thing of the charger being higher voltage than a fully charged battery ( 12.75 ) which does give the window motor more electromotive force to move an otherwise not moving motor on regular battery / turning alternator voltage 13.5 - 14.5 )

There is a procedure on final installation of the motor that the controller knows full up

on full up window position continue to hold button up for a few seconds

Worked for me

Regulator / scissor actuating mechanism lubing ?

When you put connector back on the door master controller , ensure the connector pins lock bar is in place as this was my issue of motor totally not running , my motor was just fine so your first step

The pins migrate away from connection to run the motor and the control

Left or right hand drive ?

Fuse X ,

I’ve been using the car battery instead of any other charger, and when I connect the matching 12 gauge power wire to the white or yellow ( and ground the other one to the metal door ) there’s only sparks and heat

 

Sparks and heat! Pretty definitive. Car-part.com for sure or everydayxj.com. The latter sold me a front harness at a good price so he’s got X30# parts for sure. Write him.
