The exterior mirror control switch supplies voltage and ground to the appropriate exterior mirror motors based on switch inputs. Each exterior mirror shares a common circuit for both up/down and left/right movement.
Possible Causes
Wiring, terminals or connectors Exterior mirror control switch (integral to the front door window control switch) Exterior mirror motor Exterior mirror
Visual Inspection and Diagnostic Pre-Checks
Inspect the exterior mirror control switch. Inspect the suspect exterior mirror for damage or obstructions.
NOTE: Clean the entire mirror assembly and glass to assist in verification of the customer concern and/or impact damage. Do not clean any mirror glass or housing with an ice scraper, razor blade, abrasive pad, harsh chemicals or petroleum based cleaning products, as these may damage the mirror glass and/or housing.
PINPOINT TEST B : A SINGLE MIRROR DOES NOT FUNCTION CORRECTLY IN ALL DIRECTIONS
(WITHOUT MEMORY MIRRORS)
NOTICE: The following step uses a test lamp to simulate normal circuit loads. To avoid connector terminal damage, use the Rotunda Flex Probe kit for the test lamp probe connection to the vehicle. Do not use the test lamp probe directly on any connector.
B1 CHECK THE EXTERIOR MIRROR LEFT AND RIGHT MOVEMENT
Ignition ON. Operate the LH and RH exterior mirrors in the left and right direction using the exterior mirror control switch.
Do both exterior mirrors move left and right?
