What Does B2195 Mean?
This code indicates the Body Control Module (BCM) has detected a short to ground in the driver's window up/down motor power circuit. The BCM monitors current flow and voltage in the window motor circuit and has identified an abnormal path to ground, preventing proper window operation. This is a body electrical fault that affects the power window control system.
Common Causes
40%
Damaged or pinched wiring harness in door jamb between body and door causing short to ground
30%
Failed driver window motor with internal short to ground
20%
Water intrusion or corrosion in window motor connector causing short circuit
10%
Faulty driver door module or window switch with internal short
Diagnostic Steps
1
Step 1: Perform visual inspection of driver door wiring harness in door jamb area for pinched, chafed, or damaged wires. Flex door open and closed while inspecting for wire damage or bare copper exposure
2
Step 2: Disconnect driver window motor connector and measure resistance from both motor power circuit terminals to ground using a digital multimeter. Reading should be greater than 10k ohms; less than 100 ohms indicates short to ground
3
Step 3: If motor tests good, inspect motor connector terminals for corrosion, moisture, or pushed-back pins. Check connector sealing and door moisture barrier integrity
4
Step 4: Disconnect BCM connector and perform continuity test from window motor power circuit wire at BCM connector to ground. Zero resistance indicates wiring harness short; infinite resistance points to BCM or door module fault
5
Step 5: If wiring tests good, substitute known-good window motor and retest circuit. Clear codes and operate window to verify repair
6
Step 6: Check for proper BCM operation by monitoring circuit voltage and current draw during window operation using bidirectional scan tool controls and multimeter
Estimated Repair Cost
$150 - $600

The most common cause of B2195 (Driver Window Up / Down Power Circuit Short to Ground) is: Damaged or pinched wiring harness in door jamb between body and door causing short to ground
Typical repair costs for B2195 range from $150 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to continue driving as this only affects window operation convenience. Repair at earliest convenience, especially if window cannot be raised, as open window creates security and weather exposure concerns.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2195 to identify the root cause.
