When Using Power Door Locks
- Replace blown fuse(s). If fuse blows before attempting to operate power door lock switches or transmitter, check suspect power circuits for a short to ground. Connect voltmeter between fuse terminals and disconnect one component at a time. If all related components are disconnected and short is still present, locate and repair short in wiring.
- If fuse does not blow before attempting to operate power door lock switches or transmitter, test power door lock system one function at a time, including transmitter, until fuse blows. When fuse blows, use schematic to determine which circuits or components are defective.
