Window motors, 1992 Ram

I don't know what you'll find in this Ram but... back in late 80s, early 90s, Ford would install the regulator complete with motor. Their door structure had punch dimples where a service tech could drill to access motor attach bolts rather than pull the entire assembly.
They had so many failures that they finally stopped servicing those motors separately. Binding regulators were killing the motors. anyway...Dealership customers had to pony up for upgraded motor/regulator assemblies or take it somewhere else to get a OEM type replacement motor only installed.
I have to add... It might be best to replace the complete assembly, especially at the drivers door. If it aint working now, you are realizing how often it is/was used. Good luck with it.
