Summary
Some 2020 Escape vehicles may exhibit a concern where the LH vents are warmer than the RH vents during A/C operation also may be intermittent. This may be caused by a partial restriction in the rubber portion of the 19A834 A/C line, found in WSM Section 412, Removal and Installation, Condenser Outlet Line. The evap temp sensor PID will generally read too warm due to its location toward the left hand end of the evaporator. First check system is properly charged with refrigerant. If so, and the concern is present, measure the temperature of the metal line before and after the rubber portion with a temperature gun. A difference of more than 3 deg’C (5.4 deg ’F) is likely due to a restriction present in the rubber portion and the 19A834 line must be replaced. Refer to WSM, Section 412. For claiming use casual part number 19A834 and applicable labor times found in the SLTS Manual.
