Installing the Delayed Blower Motor Control Module
For the following procedure, refer to the wiring diagram shown.
1. Record all pre-set radio stations.
2. Turn off all lamps and accessories.
3. Turn ignition OFF.
4. Disconnect the negative battery cable.
5. Disable the SIR. Refer to "SIR Disable/Enable Procedure" in the appropriate model year Saturn L-Series Restraints Service Manual.
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.
6. Remove the left front kick panel.
7. Remove the left front I/P fuse block.
8. Disconnect gray 68-way connector.
9. Locate RED 5.0 mm (10 gage) wire (circuit 502) at pin A11 and cut 76 mm (3 inches) from connector.
10. Using two of the wires in the splice connector, butt connect the two cut ends of the RED 5.0 mm (10 gage) (circuit 502) to the splice connector using yellow splice sleeves.
11. Reconnect gray 68-way connector.
12. Route 3rd wire in splice pack connector toward center of the console under the dash.
13. Remove radio bezel and radio.
14. Route relay (P/N 22688666) wire located at pin 87 at the relay through radio opening toward LIPFB.
15. Butt connect wire from pin 87 at the relay to the 3rd wire from the splice connector routed from the LIPFB using a yellow splice sleeve.
16. Remove left side console extension.
17. Install after blow module (P/N 22679784) under the HVAC module.
18. Locate WHT wire (pin E) at the after blow module pig tail.
18.1. Route WHT wire (pin E) through the front of dash pass through for the I/P harness to the underhood junction fuse block.
18.2. Remove top of junction block to gain access to the wires in the black 68-way connector.
18.3. Route WHT wire (pin E) into lower cavity of the UHFB.
18.4. Locate circuit 459 at pin C4 in the black 68-way connector at the UHFB.
18.5. Splice WHT wire into circuit 459 a few inches from the 68-way connector using a salmon splice sleeve.
18.6. Install top of junction block into base.
18.7. Using electrical tape or wire ties, secure white wire to the wiring harness.
19. Route remaining wires from the after blow module up into the radio cavity in the I/P.
20. Butt connect the BLK/ORN wire (pin G) from the after blow module to the relay wire from pin 85 using a salmon splice sleeve.
21. Make the following splices at the Radio gray 24-way connector.
21.1. Splice the ORN wire from pin A at the after blow module into ORN .5 mm (20 gage) wire (circuit 440) in cavity B1 using a salmon splice sleeve.
21.2. For 2001-2003 model year vehicles: splice the RED wire from pin B at the after blow module into YEL .35 mm (22 gage) wire (circuit 43) in cavity B2, using a salmon splice sleeve.
For 2004 model year vehicles: splice the RED wire from pin B at the after blow module into YEL .35 mm (22 gage) wire (circuit 43) in cavity B11 using a salmon splice sleeve.
21.3. Splice the BLK/WHT wire from pin C at the after blow module into BLK 1.0 mm (16 gage) wire (circuit 550, ground) in cavity A12 using a blue splice sleeve.
21.4. Splice the wire from pin 86 at the relay into the BLK 1.0 mm (16 gage) wire (circuit 550, ground) in cavity A12 using a blue splice sleeve.
22. For 2001-2003 model year vehicles, cut ORN 3.0 mm (12 gage) wire (circuit 52) about 45 mm (2 inches) from the HVAC/IP inline connector. Circuit 52 loops between pins A and B at the HVAC/IP inline connector.
23. Butt connect the wire from pin 87a at the relay to the section of ORN 3.0 mm (12 gage) wire (circuit 52) that goes to pin A at the HVAC/IP inline connector using a yellow splice sleeve.
24. Butt connect the wire from pin 30 at the relay to the section of ORN 3.0 mm (12 gage) wire (circuit 52) that goes to pin B at the HVAC/IP inline connector using a yellow splice sleeve.
25. Using a tie strap, secure the relay to the upper left side of the H-brace, allowing enough room to reinstall the radio bezel.
26. Using the hook and loop material provided on the after blow module, secure the module to the underside of the HVAC module and reinstall the closeout panel.
27. Connect negative battery cable.
28. Proceed to "Testing the Delayed Blower Motor Control Module" and verify operation. After operation is verified, proceed to next step.
29. Disconnect negative battery cable.
Important:
Do not install parts that have been removed until correct operation of the delayed blower module has been verified.
30. Connect electrical connections and install radio.
31. Install radio bezel.
32. Install left console extension assembly.
33. Install left I/P fuse block.
34. Install left front kick panel.
35. Enable SIR system. Refer to "SIR Disable/Enable Procedure" in the appropriate model year Saturn L-Series Restraints Service Manual.
36. Connect negative battery cable.
Tighten
Tighten the Battery Terminal Bolts to 17 N.m (13 ft-lbs).
37. Set radio station presets and set clock to current local time.
38. Clear any SIR diagnostic trouble codes that may have set during delayed blower motor control module testing. Refer to the appropriate model year Saturn L-Series Restraints Service Manual.
