Is there continuity?
YES - Check for loose wires or poor connections at climate control unit connector A (20P). If the connections are good, substitute a known-good
climate control unit, and recheck. If the symptom/indication goes away, replace the original climate control unit.
NO - Check for an open in the wires between the climate control unit and body ground. If the wire is OK, check for poor ground at G503 and/or
G601.
