Just trying to take care of a few gremlins on my '93 LS. From reviewing various posts, the side mirror ecu is suppose to be mounted in the back of the glove compartment. Unfortunately in my case, there's nothing resembling the ecu in this empty space. I have a oem manual that confirms the location but everything that resembles a ecu has different connectors than what's specified. I do have the memory switches for the mirrors, so therefore should have a ecu. Just hoping someone has actually had to replace this unit and can confirm a location.
