A/C - Water Leaks Onto Driver's Side Floor: Overview
No: TSB-11-55-003DATE: August, 2011
MODEL: See below
SUBJECT: WET CARPET ON DRIVER'S SIDE FLOOR
This TSB supercedes TSB-08-55-007, issued September, 2008, to provide a new procedure to correct a condition of HVAC drainage re-entering the vehicle due to a deteriorated seal, without removing the HVAC unit (most vehicles). This is a complete re-write and changes are not indicated.
PURPOSE
While being driven with the air conditioning on condensation created in the heater/ventilation/air conditioning unit (HVAC) drains through an outlet into the engine compartment. If the grommet that seals the HVAC case to the bulkhead detenorates air flow can force the drained condensation back into the vehicle's interior where it collects on the driver's floor.
This TSB provides a procedure to add a 90° hose extension to the drain to correct this condition in most vehicles without removing the HVAC unit.
AFFECTED VEHICLES
2006-2012 Eclipse
2007-2012 Eclipse Spyder
2004-2012 Galant
2004-2011 Endeavor
PROCEDURE
Eclipse, Eclipse Spyder, Galant
1. Open the hood.
2. Raise the vehicle on a hoist. Locate the existing heater unit drain outlet.
Vehicles with 4 Cylinder engine
3. Apply liquid soap to the inside of the short section of the drain hose.
4. Install the drain hose to the outlet tube.
a. Position the short end of the drain hose over the end of the outlet tube with the end of the hose hanging straight down.
b. Twist and wiggle the hose while applying light pressure until it contacts the foam bulkhead seal.
5. Pull on the hose with light pressure to confirm it is properly installed.
Vehicles with V6 engine
Perform this operation from under the driver's seat area looking towards the front of the vehicle.
1. Remove the bolt securing the power steering hose to the cross member.
2. Apply liquid soap to the inside of the short section of the drain hose.
3. Install the drain hose to the outlet tube.
a. Position the short end of the drain hose over the end of the outlet tube with the end of the hose hanging straight down.
b. Twist and wiggle the hose while applying light pressure until it contacts the foam bulkhead seal.
c. Make sure the hose is at least 1" (25mm) from the exhaust.
4. Pull on the hose with light pressure to confirm it is properly installed.
5. Reinstall the power steering hose bolt. Torque the bolt to 12 12 +/- 2Nm (106 +/- in-lb).
ENDEAVOR
The Endeavor drain outlet is between the bulkhead and a bulkhead reinforcement requiring that you insert the drain hose through an existing hole in the reinforcement to attach it to the outlet (see illustration above).
!! IMPORTANT!!
Installation of a drain hose cannot be performed on some Endeavors. Due to production variation the brake lines may cover up to 50% of the access hole for the HVAC drain outlet. If the position of brake lines prevents you from properly inserting the drain hose refer to Procedure B. Procedure B includes removing the HVAC assembly and replacing the bulkhead grommet seal.
Special Equipment
The following equipment will help install the drain hose on all Endeavors.
^ Guide Tube - 18" length of stiff 1/4" polyethylene tube (e.g plastic ice maker water line).
Cut one end of the guide tube at a 45° angle to ease inserting the hose into the drain tube.
