Installation of Afterblow Module

FIGURE 3 CIRCUIT DIAGRAM:

THE FOLLOWING STEPS ARE THE INSTRUCTIONS FOR THE INSTALLATION OF THE AFTERBLOW MODULE.

Important! The afterblow module will enable the blower to run at high speed for five
(5) minutes approximately fifty (50) minutes after the vehicle ignition is turned off, if the compressor was engaged for four (4) minutes or more during the last ignition cycle.

Important! All the connections of the afterblow harness to the vehicle wiring should be
spliced, using the proper techniques shown in Section 8A of the appropriate Service Manual. The splices should be made using splice clips, solder and wrapping the splice with electrical tape. Do not use instant connectors such as 3M's "SCOTCHLOK" brand.

Important! The circuit diagram shown in Figure 3 shows the circuit numbers generally
used on the subject model year car lines. However, to make sure of the correct circuits and wire colors are spliced into, refer to Section 8A of the appropriate Service Manual.

18. Disconnect the negative battery cable.

19. Remove close out panels, fuse block, trim plates, A/C control head and glove box as required to gain access to the circuits shown in the circuit diagram. Refer to Section 8A of the appropriate Service Manual for component location and service procedures.

20. Disconnect the afterblow module from its jumper harness and set the module aside.

21. Splice the black/white wire (PIN C) of the harness into the black ground wire of the A/C control head wiring (circuit # 150).
22. Splice the orange wire (PIN A) of the harness to a battery feed at the fuse block or the cigar lighter (circuit # 40).

23. Splice the red wire (PIN B) of the harness to the ignition feed wire of A/C control head wiring (circuit # 50).

24. Cut the orange high speed blower output wire (circuit # 52) of the A/C control wiring. Splice the tan/orange wire (PIN F) of the harness to the orange wire leading to the A/ C control head. Splice the black/orange wire (PIN G) of the harness to the other end of the orange wire leading to the blower motor.

25. Splice the white wire (PIN E) of the harness to the A/C compressor control wire coming out of the ECM. This is usually circuit # 458, # 459 or # 366.

26. Cut off the bare end of the blue wire (PIN D) of the harness, tape the end and fold and tape the wire to the harness.

27. Connect the negative battery cable.

28. Test the afterblow module for operation.

29. Mount the afterblow module in a convenient location under the dash, using foam insulation as necessary to ensure a rattle-free installation of the module.

30. Replace the vehicle components that were removed for the installation of the module.
