1994-97 QUEST A/C EVAPORATOR CONDENSATION LEAK AT DRAIN SEAL AND ATC SENSOR INTAKE
APPLIED VEHICLE:
All 1994-97 Quest (V40)
SERVICE INFORMATION
1.
If a 1994-97 Quest has wet carpeting in the front passenger side floor area, the cause may be from A/C condensation traveling up the outside of the
evaporator drain tube between the drain tube seal and engine room wall and into the passenger compartment.
A countermeasure drain tube seal is now available to correct this incident. The countermeasure seal has a larger sealing surface to ensure a tight seal
between itself and the engine room wall.
2.
On 1994-97 Quest vehicles with Automatic Temperature Control (ATC), wet front passenger side carpeting may be caused by the above condition
and from A/C condensation that drips from the evaporator core inlet tube into the air intake tube for the ATC in-vehicle temperature sensor. The
condensation then passes through the connection of the air intake tube and the mating flexible hose and drips onto the carpeting.
A countermeasure evaporator core is now available to correct this incident. The new evaporator core has a revised inlet tube shape to prevent
condensation from dripping into the air intake.
