Power Windows Control Module Fault

There’s a problem with the power windows control module.

Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.

What it means (plain English)

The power window control module is not communicating properly, which means the switches may not work right. This could be from a wiring issue or a bad control module.

What the computer is actually seeing

The system has detected a fault in the power windows control module circuit or the module itself is malfunctioning, which can trigger a warning light and disable the window controls.

What a healthy reading looks like

The power window control module should show a voltage supply of around 12V with proper ground; the module should respond to switch inputs in less than 100 milliseconds.

Guided diagnostic — the DiagCoach way

Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.

  1. 11. Inspect the wiring and connectors going to the power window control module for damage or corrosion. Fix any issues found. Decision Point: Are the connectors and wires intact? If yes, proceed to step 2; if no, repair as needed.
  2. 22. Check the power supply and ground to the power window control module using a multimeter. You should see around 12V at the power terminal and a solid ground. Decision Point: Are the voltages correct? If yes, proceed to step 3; if no, fix the voltage issues.
  3. 33. Test the power window switch inputs to the module. Each switch should send a signal to the module when pressed. Use a scan tool or multimeter. Decision Point: Do the switches send proper signals? If yes, replace the power window control module; if no, repair or replace the faulty switch.

Common causes

  • Faulty power windows control module
  • Wiring harness issues or short circuits
  • Bad connectors or corrosion on terminals
