Pinpoint Test A: All Power Windows Are Inoperative
Refer to Wiring Diagrams Set 100, Power Windows for schematic and connector information. Electrical Diagrams
Normal Operation
The window control switches share a common power and ground circuit. The window control switches only receive voltage when the ignition is in the ON position.
This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
PINPOINT TEST A : ALL POWER WINDOWS ARE INOPERATIVE
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
A1 CHECK THE WINDOW CONTROL SWITCH POWER CIRCUIT
- Disconnect: LH Window Control Switch C3293A.
- Ignition ON.
- Measure the voltage between LH window control switch C3293A-2, circuit 15-AJ7 (GN/BU), harness side and ground.
Is the voltage greater than 10 volts?
Yes
REPAIR circuit 31-AJ7 (BK) for an open. TEST the system for normal operation.
No
VERIFY Central Junction Box (CJB) fuse 166 (25A) is OK. If OK, REPAIR the circuit. TEST the system for normal operation.
If not OK, REFER to the Wiring Diagrams to identify the possible causes of the circuit short. REPAIR the circuit. TEST the system for normal operation. Electrical Diagrams
