Using the trim removal tool, carefully pry open the lower mirror arm cover. It’s a handful of snap fits, so be careful not to break any.Bring out your needle nose pliers for this step. The metal clip here is keeping the mirror spring-loaded in open and closed detents.With the addition of the motor, this becomes unnecessary, so we can get rid of it. Insert the tips of the needle-nose pliers into the two opposing holes on the spring clip.Keeping some force on the pliers to keep the tips inserted, give the whole thing a firm twist. This should align the slots on the spring clip with tabs on the center shaft and it should pop right off.At this point, you can also remove the spring and plastic washer that was being held down by the spring clip.
