Thanks for the info. I thought that being in the Equinox 3rd generation identified it. I have a lot to learn as a newbie. (1st post)
Good luck.
I have replaced several wiper transmission assemblies over the years (motor included) - and several wiper motors that were serviced separately (GM and Dodge). I have never replaced one on an Equinox.
The year of the make and model is important, as someone may be aware of a recall or technical service bulletin (TSB) that may apply to a specific year model.
If you try to replace the assembly yourself, you will need a wiper-arm puller (auto parts store) and various hand tools and a plastic nail puller to remove the black plastic cowl. The wiper motor assembly is underneath, and bolts to the metal (after unplugging the motor).
