Correction
The addition of an auxiliary fan in front of the condenser radiator assembly may help to alleviate this condition. The coolant fan will come on each time
the A/C compressor is commanded on by the PCM. This fan will create a roaring sound when operating. Follow the attached procedure to install an
auxiliary electric cooling fan to the front of the condenser and radiator assemblies.
With the jumper harness, P/N 88880045, and connector kit, P/N 12126452, on the bench, perform the following modifications:
1.
Using the electrical tool kit yellow handled tool, # 12014012-1 7J04848, remove the terminals and WHT wires from the connector of the
connector kit, P/N 12126452.
2.
Using your fingernail or a small screwdriver, spread the terminal wings that are over the weather pack seal.
3.
Slide the blue weather pack seal onto the WHT wire in order to allow the removal of the metal terminal from both of the WHT wires. Save the
blue weather pack seals.
4.
Remove the green connector to relay locking tab of the jumper harness, P/N 88880045.
5.
Disconnect the relay from the connector.
6.
Remove the green TPA from the relay connector.
7.
Remove the RED wire from cavity 87 of the relay connector.
8.
Remove the electrical tape from each end of the conduit and the wires.
9.
Identify the RED wire, with the small eyelet on the end, and pull this wire from the conduit. This is the wire that was in cavity 87 of the relay
connector. By pulling on the end, the wire can be removed from the conduit quite easily.
10.
Carefully strip the black insulator from the eyelet area of the RED wire you just removed from the conduit.
11.
Cut the wire as close to the metal eyelet to wire crimp as possible.
12.
Place one of the saved blue weather pack seals onto the RED wire (big end first).
13.
Strip 5 mm (3/16 in) of the insulation from the end of the RED wire.
14.
Using the proper crimping tool, install a terminal, P/N 12010182, to the RED wire.
15.
To a piece of 14 or 16 gauge black wire about 178 mm (7 in) long, install the other saved blue weather pack seal from the other WHT wire (big
end first).
16.
Strip 5 mm (3/16 in) of the insulation from both ends of the BLK wire.
17.
Using the proper crimping tool, install a terminal, P/N 12010182, to the end of the BLK wire with the blue weather pack seal.
18.
On the other end of the BLK wire, install a ring terminal, P/N 02984172.
19.
Slide a section of conduit, P/N 08919354, over the full length of the RED wire and secure with a wrap of electrical tape at both ends.
20.
Insert the terminal of the RED wire into cavity B of the connector, P/N 12126452 (the one you removed the WHT wires from).
21.
Insert the terminal of the BLK wire into cavity A of the connector, P/N 12126452 (the one you removed the WHT wires from).
22.
Insert the terminal of the RED wire back into cavity 87 of the relay connector.
23.
Inspect the wires going into the relay connector. On the bottom of the relay connector are corresponding numbers.
