Master Power Window Switch Input Test
- Turn ignition off. Disconnect master power window switch. Using an ohmmeter, ensure continuity is present between 16-pin connector, terminal A5 (Black (2) wire) and 3-pin connector, terminal B2 (Black (1) wire).
- Turn ignition on. Using a voltmeter, ensure battery voltage is present between ground and terminals A1 (Blue/Black wire), A2 (White/Yellow wire), A6 (White/Black wire) and A7 (Green/White wire).
- Using fused jumper wires, connect terminal A7 (Green/White wire) to terminal A16 (Red/Yellow (1) wire) and terminal A5 (Black (2) wire) to terminal A14 (Red/Blue (1) wire). Using a voltmeter, check for voltage between terminal A8 (Red wire) and driver-side window motor ground (Black wire). Voltage reading should be 6 volts as window motor runs.
- Using fused jumper wires, connect terminal A2 (White/Yellow wire) to terminal A9 (Yellow/Green wire), and terminal A11 (Yellow wire) to terminal B2 (Black (1) wire). Right rear window motor should run.
- Using fused jumper wires, connect terminal A1 (Blue/Black wire) to terminal A10 (Blue wire), and terminal A12 (Blue/Yellow wire) to terminal B2 (Black (1) wire). Right front window motor should run.
- Using fused jumper wires, connect terminal A6 (White/Black wire) to terminal A13 (Green wire), and terminal A15 (Green/Blue wire) to terminal B2 (Black (1) wire). Left rear window motor should run.
- Using fused jumper wires, connect terminal A7 (Green/White wire) to terminal A14 (Red/Blue (1) wire), and terminal A16 (Red/Yellow (1) wire) to terminal A5 (Black (2) wire). Left front window motor should run.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
