• Q: How to replace the Auxiliary Blower Motor with RPO Code E59 on 2006 Buick Terraza?

  A: To swap the auxiliary blower motor (with E59 code) you should first take off the left lower trim panel before unplugging both the auxiliary blower motor and resistor electrical connections. Unbolt and clip the lower auxiliary air distribution duct away before taking out its elements. Detach the auxiliary blower motor housing by unscrewing its screws then pull out the motor assembly. Move the auxiliary blower motor housing from the HVAC unit to reach the mounting screws underneath it where the auxiliary blower motor connects to the housing. Attach the auxiliary blower motor to the blower motor housing first and then fix it using mounting screws tightened to 1.6 N.m (14 lb in). Insert the rear tabs of the blower housing at their respective points on the HVAC module and fasten the auxiliary blower motor housing screws by tightening them to 1.6 N.m (14 lb in). Put the lower auxiliary air distribution duct in place then attach its retainers and bolts before tightening them to 10 N.m (89 lb in). Realign the auxiliary blower motor electrical connector and electrical resistor before placing the left lower quarter trim panel back in its position.
