1) If neither the radiator fan nor the condenser fan operate,
check fusible link No. 5 (40-amp). See WIRING DIAGRAMS. If only the
condenser fan does not operate, check dedicated fuse No. 8 (20-amp).
2) If the condenser fan operates in all speeds except low and
A/C compressor clutch does not enter the ON state, check for A/C
compressor lock controller unit output signal. If the A/C compressor
clutch does enter the ON state, check condenser fan low speed relay
operation.

speeds except high, check PCM. See appropriate G - TESTS W/CODES
article in ENGINE PERFORMANCE. If fan operation is not as specified,
check wiring harness for opens or shorts. Repair as necessary.
