ISSUE
Some 2004-2006 F-150 and 2006 Mark LT vehicles may exhibit water leaking back into the cab and on to the passenger floor from the A/C plenum
drain tube area.
ACTION
Refer to the following Service Procedure to determine if the water leak is from the air conditioning drain tube.
SERVICE PROCEDURE
1.
Verify that the water leak is from the heating ventilation air conditioning (HVAC) case drain seal and not from another source. Pull back the carpet
on the passenger floorboard and feel the HVAC drain tube seal for water (Figure 1A-1B) The concern may be verified easier with the front of the
vehicle slightly elevated.
a.
If there are signs of water or moisture at the drain tube seal, continue on with the TSB.
b.
If there are no signs of water or moisture, follow normal diagnosis and repair procedures.
