Delayed Blower Motor Control Module Diagnosis & Activation

Delayed Blower Motor Control Module Diagnosis








VEHICLE RUNNING, HIGH BLOWER SETTING DOES NOT OPERATE BLOWER DOES NOT OPERATE AFTER SPECIFIED DELAY TIME (MAKE SURE THAT ALL WIRES TO MODULE ARE PROPERLY CONNECTED. USE A VOLTMETER TO CHECK THAT THE PROPER SIGNAL IS APPLIED TO EACH WIRE.)

Delayed Blower Motor Control Activation Procedure (for C68 automatic climate control Systems only)

Important:
This procedure is for vehicles equipped with automatic climate control systems (RPO C68) only. If vehicle is equipped with a manual HVAC system (RPO C60), go to "Delayed Blower Kit Installation" section in this bulletin.

Before starting the following procedure, obtain the following parts:

^ 3 Wire Splice Connector, P/N 22709318

^ Splice Sleeves - Yellow, P/N 12089191 (need 3 sleeves)

1. Disable SIR system. 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.

2. Record radio presets stations and disconnect negative battery cable.

3. Remove lower left garnish molding covering the Lower Instrument Panel Fuse Block (LIPFB).

4. Remove nuts holding the fuse block in place. (One nut towards front of vehicle, one rearward.)





5. Remove the gray 68-way IP connector at the LIPFB.





Important:
For steps 6-10 refer to electrical schematic shown.

6. Locate Circuit 268, in cavity C12 (yellow 3.0 mm wire), in the gray 68-way connector.

7. Remove Circuit 268 from cavity C12 in the connector:

7.1. Remove the terminal position assurance (TPA) retainer.

7.2. Insert the terminal lock release tool into the front of the connector cavity. Pull wires and terminal out of the back of the connector.

7.3. Reinstall the TPA.

8. Cut the terminal end off circuit 268 and discard.

9. Locate circuit 502, in cavity A11 (red 3.0 mm wire), in the gray 68-way IP connector.

10. Cut circuit 502 about 51 mm (2 in.) from the connector.

11. For information on splicing wires, refer to "wiring Splicing" instructions in this bulletin.

Using the 3-wire splice connector (P/N 22709318), splice the three cut ends of circuits 268 and 502 to the three wires in the connector, using the yellow splice sleeves.

Important:
For step 11 refer to electrical schematic.

12. Reinstall the gray 68-way IP connector to the LIPFB.

13. Using a tie strap, secure the splice connector to the IP harness out of the way of the LIPFB.

14. Reinstall the LIPFB to the mounting studs (1 forward, 1 rearward).

15. Install nuts.

16. Install lower left garnish molding.

17. Enable SIR system. Refer to "SIR Disable/Enable" procedure in the appropriate model year Saturn L-Series Restraints Service Manual.

18. Connect negative battery cable.

Tighten

Tighten the Battery Terminal Bolts to 17 N.m (13 ft-lbs).

19. Set radio station presets.
