16. Check for continuity between the No. 14 terminal of
climate control unit connector B (26P) and the No. 1
terminal of the power transistor 5P connector.
Go to step 17.
Repair open in the wire between the climate
control unit and the power transistor.
17. Check for continuity between the No. 14 terminal of
climate control unit connector B (26P) and body
ground.
Repair short to body ground in the wire
between the climate control unit and the power
transistor.
Go to step 18.
18. Reconnect climate control unit connector A (8P) or
