HOUSING-FRESH AIR INLET
WARNING: Refer to the applicable warnings and cautions for this system before performing the following operation (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - WARNINGS) and (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - CAUTIONS). Failure to follow the warnings and cautions could result in possible personal injury or death.
NOTE: The fresh air inlet housing must be removed from the vehicle for removal of the HVAC housing.
NOTE: Early model year vehicles use four nuts to secure the fresh air inlet housing to the dash panel. Vehicles built later in the model year use only two nuts to secure the fresh air inlet housing. If replacing a early model year design fresh air inlet housing with the late model year design housing, a stud will need to be removed from the dash panel to allow the new design housing to mount properly.
1. Disconnect and isolate the negative battery cable.
2. Remove the cowl top panel from the dash panel (Refer to 23 - BODY/EXTERIOR/PANEL-COWL TOP - REMOVAL).
3. Remove the two bolts (1) that secure the strut support (2) to the left side strut tower (3).
4. Disengage the wiper motor (5) from the bracket (4) located on the strut support.
5. Disengage the retainer that secures the wire harness (4) to the bottom of the strut support (3).
6. Remove the purge solenoid (5) from its mounting bracket and position the solenoid out of the way.
7. Remove the two bolts (1) that secure the strut support to the right side strut tower (6) and remove the support from the engine compartment.
8. Position the powertrain control module (PCM) or the engine control module (ECM) (2) (depending on engine application) out of the way.
9. Remove the push-pin retainer (1) that secures the fresh air inlet housing (2) to the right inner fender (6).
10. Disengage the wire harness retainer (3) from inside the bottom of the fresh air inlet housing.
11. Remove the push-pin retainer (5) that secures the insulator (4) to the front of the fresh air inlet housing and position the insulator out of the way.
12. On all models, remove the two nuts (1) that secure the fresh air inlet housing (5) and air inlet water separator (2) or particulate air filter (8) and housing (7) (depending on application) to the dash panel (4).
13. On early model year vehicles, remove the fresh air inlet water separator or particulate air filter and housing (depending on application) from inside of the fresh air inlet housing.
14. On early model year vehicles, reach into the fresh air inlet housing and remove the two nuts (3 and 6) that secure the fresh air inlet housing to the dash panel and remove the housing from the dash panel.
15. On late model year vehicles, remove the fresh air inlet housing and air inlet water separator or particulate air filter and housing (depending on application) as an assembly from the dash panel.
(#2 is only on vehicles equipped without the filter)
