Heater Outlets - Emit Moisture/Condensation
NO.: 24-06-93GROUP: Air Conditioning
EFFECTIVE DATE: Mar. 12, 1993
SUBJECT:
Moisture Coming Out Of The Heater Outlets
MODELS:
1991-1993 (AA) Acclaim/Spirit/LeBaron Sedan
(AP) Sundance/Shadow/Shadow Convertible
SYMPTOM/CONDITION:
Some vehicles may exhibit moisture/condensate exiting the heater outlets when operating the A/C system in high ambients and/or high humidity with the blower switch on high and air flow in the bi-level mode for extended periods of time.
PARTS REQUIRED:
1 Resistor Block 4462841
2 Heat Shrink Sleeve 4419644
2 Tie Strap 6015756
1 Wire Overlay 4741933
REPAIR PROCEDURE:
This bulletin involves replacing the resistor block and installation of a wire overlay harness from the resistor block to the blower motor circuit.
1. Disconnect the battery.
2. Remove the glove box, as outlined in the appropriate service manual, to gain access to the blower motor and resistor block wiring harnesses. Also remove any relay mounting brackets attached to the upper glove box opening. Locate the blower motor wiring harness black 2-way connector and carefully remove it from its mounting surface. Disconnect the connector.
3. In the engine compartment, remove the existing blower motor resistor block, as outlined in the appropriate service manual, and replace it with resistor block P/N 4462841, see Figure 1.
4. The wire overlay P/N 4741933 has a unique terminal on each end. 1991, 1992 and early 1993 vehicles use one style terminal while later 1993 vehicles use a different terminal. Only one terminal will be used as determined by the style of the black 5-way connector for the resistor block. If the connector and terminal appear as identified in Figure 2, cut off and discard the terminal on the other end of the wire overlay. For all other style connectors, cut off the terminal identified in Figure 2.
5. Remove the plastic wedge on the black 5-way connector for the resistor block, insert the female terminal end of the wire overlay, P/N 4741933 into the open cavity, see Figure 3. Reinstall the plastic wedge.
6. Locate the blower motor resistor wiring harness grommet and carefully push the grommet and harness through the dash panel. Feed the wire overlay P/N 4741933 through the dash also. In the passenger side compartment, using an awl or similar tool, make a hole in the grommet as indicated in Figure 4. Feed the open end of the wire overlay through the grommet on the side indicated. Using two tie straps, P/N 6015756, secure the overlay wire to the existing blower motor resistor harness. Feed the wire overlay and blower motor resistor wiring harness back through the hole in the dash panel, and secure the grommet in place and plug the black 5-way: connector onto the new resistor block.
7. On the inside passenger side compartment, cut the C7 (12BK/TN*) wire approximately 2" from the blower motor wiring harness, black 2-way connector, see Figure 5. Seal off the harness end of the wire with heat shrink sleeve P/N 4419644. Slide another heat shrink sleeve P/N 4419644 over the wire overlay. Splice and solder the overlay wire P/N 4741933 to the short length of wire left at the connector, following the wiring repair procedures outlined in the appropriate service manual. Reinstall the black 2-way connector to the blower motor harness connector.
8. Reinstall the glove box and all parts removed gaining access to the blower motor resistor in the engine compartment. Reconnect the battery and verify that the A/C and heater blower operates on all four speeds.
