CAUTION!
Before beginning repairs on the electrical system:
- Obtain the antitheft radio security code.
- Switch the ignition off.
- Disconnect the battery Ground (GND) strap.
- After reconnecting battery, re-code and check operation of antitheft radio. Also check operation of clock and power windows.
- Immediately plug open connections on A/C components to prevent dirt and moisture contamination.
NOTE:
- Before carrying out any work on the A/C refrigerant system, refer to "A/C Refrigerant System, Safety Measures" [1][2]Technician Safety Information
- Except where indicated with *, all system components illustrated must only be serviced or replaced after discharging refrigerant system.
During servicing, all couplings, fittings and related fasteners must be torqued to specifications.
