power window motor

[84-78040]

windows on my truck are really slow going up & down, saw some on ebay that say 12 tooth motors, what is the diffrence between this 12 tooth motor to the original motor? how many teeth does the original come with?
has anyone here used this motors, and if so, do they work faster??

When I've ordered and replaced motors, mine were remanufactured originals. They're no faster or better than the OEM parts, but the old ones just get slow over time. I've had it in mine where someone put a lower amperage fuse in the power windows, and they worked a little faster after I fixed it. Once you replace it, though, it'll work as good as a new car.

It's all about supplying more voltage to the motors-the best way is with the use of relays-convert the switches to relay ground triggers and you'll be happy!
