9. Measure the voltage between the No. 11 terminal of climate control unit connector B (20P) and body ground.
Is there about 5 V?
YES - Check for loose wires or poor connections at climate control unit connector B (20P) and at the A/C pressure switch 2P connector. If the

control unit.
NO - Repair open in the wire between the climate control unit and the A/C pressure switch.
10. Using a Backprobe Set, measure the voltage between the No. 21 terminal of ECM connector A (31P) and body ground with the ECM connectors
connected.
Is there about 5 V?
YES - Repair open in the wire between the ECM and the A/C pressure switch.
NO - Check for loose wires or poor connections at ECM connector A (31P). If the connections are good, substitute a known-good ECM, and
recheck. If the symptom/indication goes away, replace the original ECM.
