Installation of Afterblow Module

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 module 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 the 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 vehicles. However, to make sure of the correct circuits and wire colors are spliced into, refer to section 8A of the Service Manual.

25. Disconnect the afterblow module from the jumper harness and set the module aside.

26. Splice the black/white wire (pin C) of the jumper harness into the black ground wire (circuit # 150) in the black connector (cavity # 12) of the A/C control assembly wiring.

27. Splice the red wire (pin B) of the jumper harness into the pink/black wire (circuit # 750) of the black connector (cavity # 4) of the A/C control assembly wiring.

28. Cut the orange blower Hi speed out put wire (circuit # 52) of the black blower switch connector of the A/C control assembly wiring. Splice the tan/orange wire (pin F) of the jumper harness to the orange wire from the A/C control assembly. Splice the black/orange wire (pin G) of the jumper harness to the other end of the orange wire.

29. Splice the orange wire (pin A) of the jumper harness into the battery feed wire (circuit # 40) at the fuse block or the cigar lighter.

30. Splice the end of the green wire, that is routed to the engine compartment to the white wire (Pin E) of the jumper harness.

31. In the engine compartment, splice the green wire into the green/yellow (Circuit # 459) at either the A/C compressor relay (Cavity # 1) of the R.H. electrical center or the ECM (Cavity A12).

32. Connect the negative battery cable.

33. Test the afterblow module, per the following procedure.

34. Cut off the bare end of the blue wire (Pin D) of the jumper harness, tape the end and fold and tape wire to the harness.

35. 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.

36. Install the secondary dash panel, the splash shields and return engine to its proper position.

37. Finish the installation of the dash components and close out panels.
