Step 2:
Discharge and recover the air conditioner refrigerant. Drain the engine coolant from the cooling system to a clean container.

not necessary, refrigerant system is cpl. separate and no need to touch.

Step 3:
Prepare to remove components within the dashboard. Apply the parking brake, place the transmission in second gear (automatic) or fourth (manual), tilt the steering wheel as low as it will go and turn the ignition switch to the "On" position.

E32 and E34 do not have a tilting steering wheel, only telescope style.

Step 4:
Disconnect all attachments to the heater/air conditioner module within the engine compartment. Disconnect the battery heat shield, intake manifold, air injection check valve hose, heater pipe assembly, Accumulator hose, evaporator tube and HVAC module drain tube.
*

no need to touch the AC system.
Battery heat shield? The battery is in the trunk! there is no heat shield. Nothing inside the engine room should be touched for this repair.

Step 5:
Disassemble the dashboard, then remove it with an assistant's help. This includes removing the center console, gear shift boot, ashtray, glove compartment, Connector Positive Assurance, Sensing and Diagnostic Module, blower motor, all panels, connectors, ducts, nuts, bolts and switches.
*

no need to touch the blower motor, that is below the cowl where the wiper motor is.

I assume you talk about another model, but not E32 / E34.
