Troubleshooting

TROUBLESHOOTING:





Use the matrix chart shown as a guide to repairs. Verify necessary inputs to the A/C Control Assembly from the vehicle prior to disassembly. Use the repair manual, A/C System section, to validate inputs such as B+, ILL+, ground, etc..

NOTE: If symptoms still exists after the suspect areas have been tested and found not to be faulty, replace the amplifier.
