# ODOR FROM A/C OUTLETS REPAIR PROCEDURE

#### MODELS AFFECTED: 1985-1987 ELECTRA AND PARK AVENUE 1987 LESABRE

Some 1985-1987 Electra/Park Avenues and 1987 LeSabres may experience odors emitted from the air conditioning system, during various operating conditions. Odor may be the result of debris in the heater/evaporator core. To correct this condition, the following procedure should be utilized:

1. Remove power module (C68) or resistor on (C60) option.

#### CAUTION:

Power module or resistor may be hot.

2. Check heater/evaporator case for debris. Remove any debris present through power module/resistor opening.

3. Insert nozzle of siphon-type parts cleaning gun, capable of delivering a minimum of two ounces per minute of liquid when driven with shop air at 80-90 psi, through the power module/resistor opening, place the siphon hose into a container of undiluted disinfectant*, such as Clorox, or equivalent.

4. Direct spray toward evaporator face to ensure adequate coverage of the corners and edges, completely saturating the entire core. Use one quart of disinfectant.

#### CAUTION:

Wear safety goggles. Do not get disinfectant in eyes or on clothing. Disinfectant is harmful if swallowed and may irritate skin.

5. Check underneath vehicle to verify proper evaporator drain operation. If necessary, unclog obstruction. NOTICE: LeSabres H37 coupe, H69 sedan and Electra Limited X69 Sedans have an insulation type material, with drain slits, covering the bottom of the evaporator case. If necessary, increase size of drain plug slits with a razor blade or sharp knife.

6. Allow the core to soak for approximately five minutes.

7. Rinse the evaporator core with one quart of clean water using the spray gun.

8. Reinstall the power module/resistor.

* In September, 1987, an air conditioning system disinfectant will be available through GMSPO for the cleaning procedure.
