Blower Motor and its bracket located just below the windscreen wiper on an E30 means disconnecting all wiring from the unit, before taking out either the linkage or the whole assembly, blower plate, arms and grill. The installation process involves attaching washers and nuts to linkages then adding shaft covers followed by left pivot links, grille, arms driven by blowers, plate fans as well as motors.For E36 models this includes removing different pieces depending upon whether they are two door cars or four doors such as wipe blades, plenum cover, injector cover, because it has different steps for 4D vehicles than those for 2D ones such as turbine blade wipers in place of weed eaters. Reinstalling involves connecting back the washer motor, aligning links with gears on each side of mechanism's base plate by adjusting bolts' tightness over which negative battery cable can be fitted at last together with windshield brush pieces sitting tightly above all these through which electrical stream passes.
