In this article, we’ll walk you through the steps to diagnose and solve B1742 mirror passenger vertical switch circuit open issues.

Step 1: Check the Fuse

The first step in diagnosing the issue is to check the fuse. Locate the fuse box in your car and find the fuse for the mirror passenger vertical switch circuit. Check if the fuse is blown or damaged. If it is, replace it with a new one of the same amperage.

Step 2: Check the Wiring

If the fuse is not the issue, the next step is to check the wiring. Start by inspecting the wiring for any visible damage or wear. Look for any frayed wires or loose connections. If you find any issues, repair or replace the wiring as necessary.

Step 3: Check the Switch

If the wiring is not the issue, the next step is to check the switch itself. Remove the switch from the car and use a multimeter to test the switch’s continuity. If the switch is not functioning properly, replace it with a new one.

Step 4: Check the Mirror Motor

If the switch is not the issue, the problem may be with the mirror motor. Use a multimeter to test the motor’s continuity. If the motor is not functioning properly, replace it with a new one.

Step 5: Check the Control Module

If none of the above steps have solved the issue, the problem may be with the control module. Use a diagnostic tool to check for any error codes related to the control module. If there are any error codes, replace the control module with a new one.
