Refer to the symptom • Before performing symptom troubleshooting, check for powertrain DTCs (see page 11-3). 1. Check the No. 20 (30 A) fuse in the under-hood fuse/relay box, and the No. 30 (7.5 A) fuse in the Go to step 2. Replace the fuses, and recheck. If the fuses blow again, check for a short in the No. 20 (30 A) 2. Remove the A/C condenser fan relay from the auxiliary under-hood fuse/relay box, and test it Go to step 3. Replace the A/C condenser fan relay. 3. Connect the HDS to the DLC (see page 21-8). 4. Turn the ignition switch ON (II). 5. Turn on the A/C on the HVAC control unit. 6. Check the FAN LOW CTRL in the PGM-FI Data List with the HDS. Go to step 7. Substitute a known-good PCM (see page 11-8), and retest. If the symptom/indication goes away 7. Measure the voltage between the A/C condenser fan relay 4P socket No. 1 terminal and body ground. Go to step 8. Repair open in the wire between the No. 20 (30 A) fuse in the auxiliary under-hood fuse/relay 8. Connect the A/C condenser fan relay 4P socket No. 1 and No. 2 terminals with a jumper wire.
