TSB 19-2072

Some 2019 MKC vehicles built on 23-Jul-2018 and through 07-Nov-2018 may exhibit intermittent function of the power mirrors and/or power windows from the master switch. These symptoms may also be present with or without diagnostic trouble codes (DTCs) B1087 and/or B1088 stored in the driver door module (DDM) and/or passenger door module (PDM). This may be the result of a small impression in the left B-pillar sheet metal which has allowed water to overcome the sealing capability of the electrical harness grommet and enter connector C315. To resolve this concern, remove all moisture from the connector, apply electrical grease and seal the B-pillar wiring harness grommet to the left B-pillar sheet metal. Follow the Service Procedure steps to correct the condition on vehicles that meet all of the following criteria: * 2019 MKC * Built on 23-Jul-2018 and through 07-Nov-2018 * Intermittent function of the power mirrors and/or power windows from the master switch
