Review on 🔌 ACDelco Professional Power Window Motor Model 11M23 by David Sharma

I am testing this OEM and aftermarket Dorman motor in my 1994 GMC van. So far, the Delco motor is quieter and more powerful than the Dorman, which lowers the window quickly but raises it more slowly. This Delco motor is very affordable and seems to outperform it in quality. The mounting bracket is not threaded for mounting screws, however these screws are self-tapping. If you want to mount the motor in a tight space, I recommend using pre-threaded screws before actual installation.
