If only the blower assembly (resistor, blower motor, blower case) needs to be removed, it can be done simply by removing the foot shower duct first, then the blower assembly; the other components need not be removed.

Prior to this procedure, if the evaporator is going to be removed, the air conditioning system must be discharged by an automotive mechanic trained and certified to work on air conditioning systems. If the evaporator is not going to be removed, the A/C system need not be discharged.

  1. On vehicles with air conditioning, disconnect the drain hose, the liquid pipe and the suction hose.
  2.  
  3. Extract the glove box assembly from the dashboard.
  4.  
  5. The speaker grille cover should be removed, then the speaker itself.
  6.  
  7. Unscrew the four mounting bolts and then remove the lower frame.
  8.  
  9. Remove the right-hand side foot shower duct.
  10.  
  11. Unplug the engine control relay assembly and remove its bracket.
  12.  
  13. Disconnect the air selection control wire from the air selection damper lever.
  14.  
  15. On vehicles with air conditioning, the evaporator will need to be removed. On vehicles without air conditioning, remove the duct joint instead.
  16.  
  17. Loosen and remove the blower assembly mounting bolts, then drop the assembly down and out of the dashboard.
  18.  

To install:
  1. Secure the blower assembly in its position with the mounting bolts.
  2.  
  3. Install the duct joint (vehicles with no A/C) or the evaporator (vehicles with A/C).
  4.  
  5. Connect the air selection control wire to the air selection damper lever by following the following steps:
    1. Move the air selection control lever to the recirculation position.
    2.  
    3. With the air selection damper lever pressed inward in the direction indicated by the arrow, connect the inner cable of the air selection lever, then use a clip to secure the outer cable.
    4.  

  6.  
  7. Install the engine control relay assembly and its bracket.
  8.  
  9. Secure the right-hand side foot shower duct in place and tighten the retaining bolts.
