My 45 years old power window lift motors are slow and sound like they are about to die. I'm tired of people saying "Dude, what's up with your windows? Why are they so slow? And what's that terrible sound?"

So, does anyone have experience with these motors? Are the faster and quieter than the stock motors? Dorman say they are for 1964 to 1981 Chrysler's.

Ive installed a few hundred Dorman motors, although not this particular part number. Can't remember ever having an issue. And they are almost always faster than OE.

True. I found three options:

Cardone - Remanufactured, so I would get the same performance as my existing working units. Maybe a little better.

VDO - New, similar to the design Dorman uses but it's out of stock everywhere.

And Dorman. Yuck! But it has a lifetime warranty and suppose to be faster and stronger than stock lift motors.
 
Thanks! Summit Racing price matches!
These motors look like they will do a great job! I had a pair of motors that I took apart/cleaned/lubed and did not see it make much of a difference. Still get that noisy/whiny and sluggish performance.

Rockauto also has a discount code for 5% OFF! Paste it into the box that says 'How did you hear about us?' during checkout.

A couple of years ago, I was headed to Alaska in our motorhome. While in the "wilds" of Canada, my electric steps stopped working. After a couple of days of using a plastic stepping stool and rope, I got to a city and went looking for a replacement motor and transmission at three different rv shops. The last shop had the motor assembly. The bad news was that it cost $350 Canadian ($270 American). Replaced the motor assembly and then the steps worked fine.
I disassembled the motor and transmission in my spare time and found the motor worked fine. The problem was in the transmission. After some research, I found out that the motor was also used in electric car windows, in my case , a 2002 Taurus, which was available for about 1/4 the price that I paid. The problem that caused the failure was a few white plugs in the transmission. I found some at a local auto parts store and put them in the old motor. Now I have a spare if it happens again, but it was an expensive lesson.

The motor that used those plastic dowels goes way back probably all through the eighties. It was very common that these would crumble with age and the motor would just free wheel. I don’t think ford ever serviced them individually, but cardone still sells a kit to repair those motors.
 
Old thread I know.....

But beware, apparently Dorman has a few versions of this motor out there all carrying the same 742-300/1 part number. Some will not physically bolt up to your regulator. YMMV.
