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.
The parts shown are required to install the delayed blower motor control module.
CAUTION:
WHEN PERFORMING SERVICE ON OR AROUND SIR COMPONENTS OR SIR WIRING, FOLLOW THE CAUTIONS AND PROCEDURES IN THE SIR SERVICE MANUAL TO TEMPORARILY DISABLE THE SIR SYSTEM. FAILURE TO FOLLOW THE DISABLE PROCEDURES COULD RESULT IN POSSIBLE AIRBAG DEPLOYMENT, PERSONAL INJURY OR OTHERWISE UNNEEDED SIR SYSTEM REPAIRS.
1. Disable SIR system. (Refer to "SIR Disable/Enable" procedure in the 2000/2001 Restraints Service Manual.)
2. Record radio presets stations and disconnect negative battery cable.
3. Remove left side I/P lower dash insulator retainers.
4. Pull insulator rearward to detach from forward insulator retainers.
5. Remove left side console extension.
6. From driver's side of vehicle, wipe clean the bottom horizontal surface of the HVAC module.
7. Peel backing off of hook and loop retainer and install delayed blower control module with wiring harness facing towards passenger side and ensure back edge of delayed blower control module is flush with the side of the HVAC module. Press firmly to seat.
8. Remove radio bezel.
9. Remove radio and disconnect electrical connectors.
10. From Center "P opening:
10.1 Route delayed blower motor control module harness down to delayed blower control module by placing the harness between the left side H Brace and HVAC module. Make sure the harness is routed between the main I/P body harness and the HVAC module.
10.2 Connect jumper harness to delayed blower motor control module pigtail.
IMPORTANT:
For steps 11 though 15, refer to the electrical schematic shown.
IMPORTANT:
For information on splicing wires, refer to "Wiring Splicing" instructions in this bulletin.
11. Make the following splices at the HVAC inline BLK 12-way connector.
11.1 At Pin A, cut orange wire (circuit 52), 76 mm (3 in.) from connector on the side going to the HVAC control head, then:
11.2 Using a yellow splice sleeve, splice the ORN 5.0 mm (10 gage) wire that goes to the HVAC control head into TAN/ORN .5 mm (20 gage) wire (Pin F) from delayed blower control module.
11.3 Using a yellow splice sleeve, splice the other half of the ORN 5.0 mm (10 gage) wire from HVAC inline connector that goes to the I/P body harness into BLK/ORN .5 mm (20 gage) wire (Pin G) from delayed blower control module.
11.4 At terminal H, using a salmon (pink) splice sleeve, splice BRN .35 mm (22 gage) wire from HVAC inline connector into RED .50 mm (20 gage) wire from delayed blower control module.
12. Make the following splices at the Radio gray 24 way connector:
12.1 At terminal B3, using a salmon (pink) splice sleeve, splice ORN .50 mm (20 gage) wire from Radio 24 way connector into ORN .50 mm (20 gage) (Pin A) wire from delayed blower control module.
12.2 At terminal A12, using a blue splice sleeve, splice BLK 1.0 mm (16 gage) wire from Radio 24-way connector into BLK/WHT .50 mm (20 gage) (Pin C) wire from delayed blower control module.
13. From inside the vehicle, carefully drill a hole through left side (ten o'clock position) of engine harness grommet, using a 2.0 mm drill bit.
14. Locate WHT wire (pin E), from delayed blower module and tape the wire onto the end of an awl and push through drilled hole in grommet. From engine compartment untape WHT wire from awl and pull wire all the way through.
15. Remove battery shield.
16. Unsnap engine coolant reservoir line from the fuse block cover.
17. Open UHFB and disconnect the UHFB black 68-way connector (L61) or gray 68-way connector (L81) and then:
17.1 Locate and remove terminal C4 (L61) GRN/WHT wire or A7 (L81) BLK/WHT wire from the black (L61) or gray (L81) UHFB 68-way connector.
17.2 Cut off terminal end from the GRN/WHT wire or BLK/WHT wire.
17.3 Splice GRN/WHT (L61) or BLK/WHT (L81) wire from UHFB 68-way connector and WHT wire from delayed blower control module onto terminal end PN # 12034046.5 mm to .8 mm (20 to 18 gage).
17.4 Place terminal end back into UHFB 68-way connector at terminal C4 (L61) or A7 (L81).
17.5 Connect 68-way connector to UHFB.
18. Open Engine harness conduit from UHFB to bulkhead.
19. Route WHT wire from delayed blower motor along this harness, placing the wire inside the conduit.
20. Using electrical tape spot tape the engine harness.
21. Close UHFB.
22. Reinstall coolant reservoir line.
23. Reinstall battery shield.
24. Inside the vehicle, solid tape the WHT wire from delayed blower motor to I/P harness every 2-3 inches.
25. The BLU wire from the delayed blower motor is unused. Tape end of BLU wire and tape back to the jumper harness of the delayed blower control module.
26. Attach top half of "Notice" label provided in kit to blower motor cover. This can be accessed by removing the passenger compartment air filter in the engine compartment. Attach the bottom half of the "Notice label to the inside of the left console extension assembly.
27. Connect negative battery cable.
Torque:
Battery Terminal Bolts: 17 N.m (13 ft-lbs)
28. 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 until correct operation of the delayed blower module has been verified.
29. Disconnect negative battery cable.
30. Connect electrical connections and install radio.
31. Install radio bezel.
32. Install left console extension assembly.
33. Enable SIR system. (Refer to "SIR Disable/Enable" procedure in the 2000/2001 Restraints Service Manual.)
34. Connect negative battery cable.
Torque:
Battery Terminal Bolts: 17 N.m (13 ft-lbs)
35. Set radio station presets.
36. Clear any SIR diagnostic trouble codes that may have set during delayed blower motor control module testing. (Refer to the 2000/2001 Restraints Service Manual.)
