NO: 24-02-95GROUP: Heater & A/C
DATE: Jan. 27, 1995
SUBJECT:
Leaves/Debris in Heater-A/C System
MODELS:
1995 (PL) Neon
SYMPTOM/CONDITION:
^ Debris comes out of the air outlets (applies to heater only equipped vehicles).
^ Noise at heater-A/C blower motor wheel due to leaves/debris in wheel.
PARTS REQUIRED:
1 NPN Hardware Cloth (3" x 24" x 1/4"), Zinc Plated or Corrosion Resistant Coating)
3 6032723 Screws
AR 4467708 Mopar Silicone Glass Sealer
AR 4655021 Windshield Cowl Screen (for vehicles built prior to Jun. 6, 1994, MDH 06-06-XX).
REPAIR PROCEDURE:
This bulletin involves installing a fabricated screen over the cowl plenum air inlet openings on all vehicles, and on some vehicles cleaning air outlets and/or installing a revised windshield cowl screen.
1. For vehicles equipped with A/C, proceed to step 5. For heater only equipped vehicles, remove all upper panel air outlets by pivoting them downward with adequate force. Remove any debris/leaves from the outlet louvers.
2. Check the defroster outlet for any debris. If debris is evident, remove the instrument panel top cover as outlined in the 1995 Neon Service Manual (Publication No. 81-270-5025), Page SE-7 and remove the debris.
3. Check the heater duct openings and remove any debris. With all outlets removed, turn blower to high and move the temperature control back and forth from cold to hot while cycling through all air distribution modes to blow out any debris in the duct system.
4. Install the instrument panel top cover, if removed. Install the air outlets. The outlets can only be installed one way, with the large diameter hinge on the left side. If noise was heard from the blower motor wheel, proceed to the next step, otherwise go to step 8.
5. Remove the blower motor and wheel assembly as outlined in the Service Manual, Pages 24-11 through 24-12. Remove any debris/leaves from the blower wheel and in the heater-A/C housing.
6. Remove any debris from the A/C condensate drain tube.
7. Install the blower motor and wheel assembly back into the heater-A/C housing.
8. Cut a section of hardware cloth as indicated (Figure 1). Cut the wire harness opening in an "X" pattern and fold inward (Figure 2).
9. Remove the wiper arm/blade assemblies.
10. Open the hood and remove the rear hood seal and windshield cowl screen.
11. Remove the blower motor resistor block, with wiring attached.
12. Align the pre-cut hardware cloth over the air inlet openings (Figure 3).
13. Carefully slide the wiring harness up through the slit in the hardware cloth to the pre-cut opening.
14. Install the resistor block over the screen. Make sure the screen does not come in contact with the elements in the resistor block (Figure 2).
15. Install three screws, P/N 6032723, to secure the screen to the cowl plenum.
16. Apply Mopar Silicone Glass Sealer, P/N 4467708, around the outside edge of the screen to eliminate any potential for buzz, squeaks or rattles.
NOTE:
VEHICLES BUILT PRIOR TO JUN. 6, 1994 (MDH 06-06-XX) REQUIRE A NEW WINDSHIELD COWL SCREEN, P/N 4655021.
17. Install the windshield cowl screen and hood seal.
18. Install windshield wiper arm/blade assemblies.
