Delayed Blower Motor Control Module Installation
IMPORTANT:Before proceeding with the installation of the delayed blower motor control module, make sure the customer is fully aware of its function and operation.
These parts are required to install the delayed blower motor control module shown.
CAUTION:
WHEN PERFORMING SERVICE ON OR AROUND SIR COMPONENTS OR SIR WIRING, FOLLOW THE CAUTIONS AND PROCEDURES IN THE APPROPRIATE YEAR SIR SERVICE MANUAL TO TEMPORARILY DISABLE THE SIR SYSTEM. FAILURE TO FOLLOW THE DISABLE PROCEDURES COULD RESULT IN POSSIBLE AIR BAG DEPLOYMENT, PERSONAL INJURY OR OTHERWISE UNNEEDED SIR SYSTEM REPAIRS.
1. Disable the SIR system. (Refer to "Disabling the SIR System" in the "1995 SIR Service Manual.")
2. Record radio preset stations and disconnect negative battery cable.
3. Remove right and left console extension assemblies.
4. Remove HVAC module lower trim panel.
5. From passenger side of vehicle, wipe clean top center surface of heater duct.
6. Remove hook side of hook and loop retainer that is attached to delayed blower motor control module.
7. Peel backing off of hook side of hook and loop retainer and apply to top center of heater duct between two structure ribs. Press firmly to seat.
8. Install edge clip on electrical connector of delayed blower motor control module.
9. Using electrical tape, solid wrap delayed blower motor control module pigtail harness from electrical connector edge to delayed blower motor control module.
10. From driver's side of vehicle:
10.1 Insert delayed blower motor control module, with pigtail harness end first and hook and loop retainer down, into cavity above forward end of heater duct.
10.2 Slide delayed blower motor control module in until rear edge is flush with heater duct edge on driver's side of vehicle.
10.3 Press down on blower motor control module to engage hook and loop retainer. (Delayed blower motor control module should fit securely if engagement of hook and loop retainer has been achieved.)
11. From passenger's side of vehicle:
11.1 Route delayed blower motor control module pigtail harness between forward edge of heater duct and carpet.
11.2 Attach delayed blower motor control module pigtail harness connector to the lower forward edge of the heater duct. Place clip as far forward as possible.
12. Using black electrical tape, solid wrap 381 mm (15 in.) of the delayed blower motor control module jumper harness, starting at electrical connector end.
13. Connect delayed blower motor control module jumper harness with delayed blower motor control module pigtail at heater duct.
14. Route delayed blower motor control module jumper harness under front heater duct, forward of rear heater duct (if equipped), to the I/P wiring harness on the driver's side of the vehicle.
NOTICE:
To prevent any possibility of a short circuit, replace any tape that is pushed back or removed from any wiring harness that is moved.
15. Disconnect black I/P harness connector and pull into driver's side footwell.
16. Disconnect gray body harness connector and pull into driver's side foot well.
IMPORTANT:
For information on splicing wires, refer to "Wire Splicing" instructions in this bulletin.
17. Make the following splices (refer to electrical wiring schematic)
17.1 At terminal C9 of instrument panel junction block (IPJB) gray 68-way connector, splice ORN wire from delayed blower motor control module into ORN wire (circuit 340A-battery feed) from 68-way connector
17.2 At terminal C10 of black 68-way connector, splice RED wire from delayed blower motor control module into BRN wire (circuit 41B-ignition) from 68-way connector.
17.3 At terminal F1 of IPJB black 68-way connector, locate ORN wire (circuit 52-HVAC blower control switch), and cut wire 51 mm (2 in.) from 68-way connector, then:
^ Splice BLK/ORN wire from delayed blower motor control module to length of ORN wire (circuit 52) that goes to black IPJB 68-way connector.
^ Splice TAN/ORN wire from delayed blower motor control module to length of ORN wire (circuit 52) that goes to HVAC blower control switch.
18. Attach ring terminal lead kit (P/N 12112245) to BLK/WHT wire from delayed blower motor control module.
19. Attach ring terminal on the BLK/WHT wire from delayed blower motor control module to ground location at H-brace. Make sure that new ring terminal is on top of existing ring terminal.
Torque:
Ring Terminal-to-Ground: 2.2 N.m (20 in.lbs)
20. Using a 1.5 m (5 ft.) length of .50 sq.mm (20 gage) wire:
20.1 At terminal J2B04 of PCM Lt. blue (DOHC) or pink (SOHC) 24-way connector, splice one end of wire to GRA wire (circuit 729 [SOHC], 729A [DOHC]-A/C relay control).
20.2 Route wire to the IPJB as follows (using electrical tape, spot tape wire to harnesses approximately every 51-76 mm (2-3 in.):
a. Tape wire to PCM branch of I/P harness.
b. Follow harness up to I/P splice packs, forward of PCM.
c. From top of I/P, route wire along I/P harness, following the main branch across, forward of beam, and then down to IPJB. Route wire to the left of cruise control connector.
20.3 Splice wire to WHT wire from delayed blower motor control module.
21. The BLU wire from the delayed blower motor control module is unused. Tape end of BLU wire and tape back to jumper harness of delayed blower motor control module. The delayed blower motor control module GRN wire is used for testing.
22. Attach top half of "Notice" label provided in kit to blower motor cover. Attach bottom half of "Notice" label to inside of right side console extension assembly.
23. Connect black I/P harness connector.
24. Connect gray I/P harness connector.
25. Connect negative battery cable.
Torque:
Battery Cable: 17 N.m (13 ft-lbs)
26. Proceed to "Testing the Delayed Blower Motor Control Module" and verify operation. After operation is verified, proceed to next step.
IMPORTANT:
Do not install parts that have been removed, except for black I/P harness and gray body harness connectors, until correct operation of the delayed blower motor control module has been verified.
27. Install HVAC module lower trim panel.
28. Install right and left console extension. assemblies.
29. Enable the SIR system. (Refer to "Enabling the SIR System" in the "1995 SIR Service Manual" for correct SIR system enable procedure.)
30. Set radio station presets.
31. Clear any SIR diagnostic trouble codes that may have set during delayed blower motor control module testing. (Refer to the "1995 SIR Service Manual.")
