A blocked cooling hose for the heater blower motor can cause the motor to overheat, draw more current, blow a fuse, or even melt its plastic
impeller. Before you order a replacement blower motor, make sure the cooling hose isn't blocked. On some models, you'll find the cooling hose molded into the blower motor housing; on other models, it's a separate piece. Check the S/M for the vehicle you're working on to determine the actual location of the cooling hose.
Here is the removal and check procedure.
BLOWER UNIT REMOVAL
WITH AIR CONDITIONING
- Remove the glove box.
- Remove the glove box frame.
Pull back the carpet and remove the kick panel. Remove the four ECM bracket mounting nuts. Disconnect the five connectors and remove the ECM and bracket.
Remove the clamp and two screws, then remove the two-piece cover
Remove the two bands as shown.
Remove the two screws and three blower unit mounting nuts.
Disconnect the three remaining connectors, and pull the blower unit away from its mounts, and "roll" the front of it down as you remove it.
BLOWER UNIT OVERHAUL
Refer to illustration for component locations and replacement, noting the following:
CONTROL ROD ADJUSTMENT
- Before reassembly, make sure that the recirculation control doors and linkage move smoothly without binding.
- When reattaching the recirculation control motor, make sure its positioning will not allow the recirculation control doors to be pulled too far. Attach the recirculation control motor and all linkage, then apply battery voltage and watch the recirculation control doors movement. If necessary, loosen the holding screw and move the recirculation control motor up or down.
Connect the recirculation control motor connector to the main wire harness and turn the FRE/REC switch to "REC". Hold the recirculation control doors closed, then connect the control rod to the clip on the arm. BLOWER UNIT INSTALLATION
Install the blower unit in the reverse order of removal, then turn it on and make sure no air leaks from its seams.NOTE:
When installing the glove box frame, the flap which covers the end of it is installed with double-sided adhesive tape.
Good luck a little bit of a project,
