Break Down And Replace The Blower Motor


REMOVAL

WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIR-BAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN AN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY OR DEATH OR DEATH.

NOTE: The blower motor is located on the passenger side of the vehicle under the instrument panel. The blower motor can be removed from the vehicle without having to remove the HVAC housing.

1. Disconnect and isolate the negative battery cable.
2. Remove the passenger side cowl trim panel.
3. Position the carpet to access the front upper screw that secures the air inlet housing.
4. Remove the recirculation door actuator.
5. Disconnect the blower motor wire lead connector from the blower motor resistor or power module, depending on application.
   1. Remove the one screw (from the top) that secures the lower air inlet housing to the upper air inlet housing.
   2. Remove the four screws (from the bottom) that secure the lower air inlet housing to the upper air inlet housing and remove the lower HVAC housing.
   3. Push the rubber grommet through the opening in the lower air inlet housing.
   4. Route the blower motor wire lead through the opening in the lower air inlet housing and remove the lower air inlet housing from the vehicle.
   5. Position the recirculation-air door as necessary to access and remove the three screws that secure the blower motor to the lower half of the HVAC housing.
   6. Gently flex the recirculation air door downward to gain access to remove the blower motor from the HVAC housing. NOTE: To aid in installation, note the position of the blower motor mounting tabs prior to removal
      1. Remove the blower motor from the HVAC housing by rotating and tilting the blower motor as necessary.
      INSTALLATION
      
      
      1. Gently flex the recirculation-air door downward to gain access to install the blower motor into the HVAC housing.
      2. Position the blower motor to the HVAC housing and tilt and rotate the blower motor as necessary to install it into the HVAC housing.
      3. Align the blower motor mounting tabs to the locations noted during removal and install the three screws that secure the blower motor to the HVAC housing. Tighten the screws to 2 N·m (17 in. lbs.).
      4. Route the blower motor wire lead through the opening in the lower air inlet housing and seat the rubber grommet.
      5. Position the recirculation door pivot shaft into the lower air inlet housing and install the inlet housing.
      6. Install the four screws (from the bottom) that secure the lower air inlet housing to the upper air inlet housing and the lower HVAC housing. Tighten the screws to 2 N·m (17 in. lbs.).
      7. Install the one screw (from the top) that secures the lower air inlet housing to the upper air inlet housing. Tighten the screw to 2 N·m (17 in. lbs.).
      8. Connect the blower motor wire lead connector to the blower motor resistor or power module, depending on application.
      9. Install the recirculation door actuator.
      10. Reposition the carpet.
      11. Install the passenger side cowl trim panel.
      12. Reconnect the negative battery cable.
      13. Perform the heater-A/C control calibration procedure.

May be a bad head gasket check oil for signs of coolant mixing in there may be a cracked head or even a bad head gasket. Going by what you said that there is NO visible leak the only other way for you to be loosing coolant if for it be burning out by engine or mixing in oil. To check for mixing check under oil cap for creamish-while residue or oil looking like milk shake. Good luck and thanks for using FIX YA

Have you checked the coolant level? If it's low, it will result in diminished heat, and could be the problem.
