YES -
Repair a short to body ground in the wire(s) between the climate control unit and the rear power transistor.?
NO -
Go to step 19.
19. Check for continuity between the following terminals of climate control unit connector B (14P) and the rear power transistor 4P connector.
Is there continuity?
YES -
Go to step 20.
NO -
Repair an open in the wire(s) between the climate control unit and the rear power transistor.?
20. Turn the ignition switch to ON (II).
21. Measure the voltage between body ground and climate control unit connector B (14P) terminals No. 13 and No. 14 individually.
Is there any voltage?
YES -
Repair a short to power in the wire(s).?
NO -
Go to step 22.
22. Reconnect climate control unit connector B (14P).
23. Test the rear power transistor See: Heating and Air Conditioning/Testing and Inspection/Component Tests and General Diagnostics/Rear
Blower Power Transistor Test.
