ISSUE:
A low speed "ticking" noise may come from the blower motor. This occurs because the blower motor is not properly sound shielded.
ACTION:
Place a sound dampening cover over the blower motor to lower the sound level. Refer to the following procedure for service details.
SERVICE PROCEDURE
1. Remove the existing blower motor. Refer to the appropriate Service Manual, Sections 12-02 and 12-03A, for the removal procedure. Discard the screw, wiring harness and wiring bracket.
2. Check the cooling hole on the motor for a plastic screen, Figure 1. If the screen is present, remove and discard it.
3. Connect the new wiring harness (F3CZ-18W586-A) to the blower motor, Figure 2.
4. Snap the plastic blower motor cover (F3CZ-18515-A) to the motor (it will be loose) while routing the wiring harness out from underneath the cover.
5. Position the cover and motor assembly into the evaporator/blower unit, then line the metal ring retainer (F3CZ-18K405-A) up with the mounting holes.
6. Tighten the assembled motor and cover to the evaporator/blower unit (2.2-2.7 N-m) (19.5-24 lb.in.) using the three (3) new screws (390039-52).
7. Connect the blower jumper harness (DB/Bk) leads to the blower resistor. Route the other lead (DB) through the molded clip on the fuse panel and connect it to the connector going to the fuse panel, Figure 3.
