I purchased a Dor-man driver's side (front left) window lift motor from Auto_zone, only about $55. Still working fine after a few months. It comes with a lifetime warranty if you keep the receipt. Two things: the mounting holes are not threaded; I tapped mine, others just forced the screw/bolts into the aluminum inserts. And the connectors that came with the new motor did not fit the Toyota harness. I removed the connector from the original motor and put it on the Toyota harness section that came with the motor. I was not impressed by the Dor-man window regulator, cheaper construction and looser/flimsier than my original used regulator which I put back in.
Kernal - based on your comments in another post, I deduced that you have now had the Dorman replacement motor in your vehicle since November of 2011 - does that sound about right? So...now that you've had it in for over a year and for portions of 2 winters, how is the window working?
I am about to pull the trigger and order the Dorman motor for the driver door. I already have a new window run from CDan for the driver door and will replace the run and motor at the same time (as well as inspect and lube the regulator and clean and lube anything else related to the window).
Also, after I remove the original motor, I plan to open it up and attempt to rebuild (replace brushes, etc.) I read on another thread that you (Kernal) attempted to service the original motor without success so I am not holding my breath. However, this write-up seems to give some hope.

Depending on how my efforts go with rebuilding the motor, I may put it back in place of the Dorman and try the same approach with the other motors. I am definitely going to replace all 4 window runs as time permits over the next few weeks. However, I will reserve judgment on whether motor replacement is needed on a case by case basis. The consensus seems to be that the accumulated wear of these parts causes the issue, but that replacing the window runs only, may be enough and has the greatest impact (assuming the motor is still operational of course).
Thanks for any further thoughts you might have now that you are a year out from your motor replacement. -James
EDIT To pose the same question to the OP, Wayne - how has your motor replacement worked out for you now that you have had it in place for 9 or so months? Any further feedback regarding the steps you took or other issues? Thanks
