A/C EVAPORATOR CASE DRAIN DRIP INSTALL NEW DRAIN TUBES

SUBJECT: A/C EVAPORATOR CASE DRAIN DRIPS INTO PASSENGER SIDE COMPARTMENT - INSTALL NEW RUBBER DRAIN TUBE

MODELS/YEARS: 1992 CUSTOM CRUISER

CONDITION: Condensate water from the evaporator drain tube can leak into the passenger compartment (passenger side floor area).

CAUSE: Under conditions of extreme humidity, air flow through the engine compartment can allow a small amount of condensate water to work past the seal of the evaporator drain tube. The water then slowly drips or seeps into the passenger side front compartment.

If there is a large volume of water, use normal diagnostic procedures to determine the cause of the leak.

CORRECTION: Inspect the evaporator drain tube for blockage, clear as required. Install the 90 degree rubber drain tube P/N 22542866 over the existing tube, pointed downward, as illustrated. This will allow the water to drain down away from the evaporator drain opening. This part is currently available from GMSPO.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
