5. Remove the bolt, then remove the trunk lid opener/
fuel fill door opener (A) from the bolt (B). 6. Disconnect the trunk lid opener/fuel fill door opener
cable (A), then remove the opener (B). Take care
not to kink the cable.
7. Install the opener in the reverse order of removal, and note these items:
 Make sure the opener cable is connected properly.
 Make sure the trunk lid and fuel fill door open properly and lock securely.
 If the trunk lid or the fuel fill door does not open properly, adjust the position of the cable end on
the opener.

SRS components are located in this area. Review the
SRS component locations (see page 24-11) and the
precautions and procedures (see page 24-13) before
doing repairs or service.
1. Do the battery terminal disconnection procedure (see page 22-68).
2. Disconnect the A/C line from the evaporator core
(see page 21-78).
3. Remove the air cleaner housing assembly (see page 11-345).
4. When the engine is cool, drain the engine coolant from the radiator (see page 10-8).
5. From under the hood, slide the hose clamps (A) back. Disconnect the inlet heater hose (B) and the
outlet heater hose (C) from the heater unit. Note the
orientation of the hoses.
Engine coolant will run out when the hoses are
disconnected; drain it into a clean drip pan. Be sure
not to let coolant spill on the electrical parts or the
painted surfaces. If any coolant spills, rinse it off
immediately. 6. Remove the mounting nut from the heater unit.
Take care not to damage or bend the fuel lines or
brake lines, etc.
7. Remove the dashboard (see page 20- 108).
8. Disconnect the connector (A) from the blower motor. Remove the wire harness clip (B).
