TECHNICAL SERVICE BULLETIN
HVAC Evaporator Case Whistle Noise In Right Footwell Area Built On 15-Feb-2019 And Through 12-Mar-2019

19-2265
05 September
2019

Model:
Ford
2019 Escape
Lincoln
2019 MKC
Issue: Some 2019 Escape and MKC vehicles built on 15-Feb-2019 and through 12-Mar-2019 may exhibit
a whistle noise from the heating ventilation and air conditioning (HVAC) evaporator core cover area where
the evaporator tubes enter the evaporator case in the right side footwell area. The noise will be most
noticeable while transitioning into maximum heat with higher blower speeds. This may be due to incorrect
evaporator core cover to evaporator case sealing that can allow an air leak and result in a whistle noise.
To correct the condition, follow the Service Procedure steps to apply a small piece of mastic sealing patch
to the evaporator case/cover joint.
Action: Follow the Service Procedure steps to correct the condition that meet all of the following criteria:
• 2019 Escape/MKC
• Built on 15-Feb-2019 and through 12-Mar-2019
• Whistle noise from the HVAC evaporator core/right footwell area
