Heated Windshield Circuit Short to Ground
Diagnostic trouble code B2113 indicates that the body control module (BCM) or climate control module has detected a short to ground in the heated windshield input circuit. The heated windshield system uses a conductive mesh embedded in the glass to defrost or defog the windshield via electrical resistance. A short to ground means the circuit voltage is abnormally low or directly connected to chassis ground, preventing the windshield heating system from operating correctly.
1. Commonly Affected Makes
2. Most Common Causes
- Wiring in the heated windshield circuit shorted to ground
- Damaged connector or harness making contact with chassis ground
- Heated windshield relay with shorted coil or contacts
- Body control module (BCM) internal failure in the detection circuit
- Heated windshield switch or activation button with internal short
- Heated windshield grid resistance leaking current to ground
3. Symptoms You Will Notice
- Heated windshield inoperative
- Heated windshield indicator light on or flashing
- BCM or climate control module stores code B2113
4. Step-by-Step Diagnosis
Scan for codes and verify B2113 is present
Visually inspect heated windshield wiring and connectors for damage or grounding
Check the heated windshield relay and its control circuit
Test the heated windshield grid resistance for shorts to ground
If all else is normal, suspect a faulty BCM or climate control module
5. Frequently Asked Questions
Is it safe to drive?▼
Yes, it is generally safe to drive, but the heated windshield will not work, which may reduce visibility in frost or fog conditions.
How much does it cost to fix?▼
Repair costs typically range from $100 to $400, depending on whether the issue is a simple wiring repair or requires replacing the BCM or windshield.
