Pinpoint Test A: All Power Windows Are Inoperative - Zephyr

WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

A1 CHECK CIRCUIT CBP02 (GN) AND CPW30 (GY/YE) FOR VOLTAGE
- Disconnect: LH Front Window Control Switch C535A.
- Disconnect: LH Front Window Control Switch C535B.
- Key in ON position.
- Measure the voltage between LH front window control switch C535A-3, circuit CBP02 (GN), harness side and ground; and between LH front window control switch C535B-3, circuit CPW30 (GY/YE), harness side and ground.

- Is the voltage greater than 10 volts for both measurements?
Yes : INSTALL a new LH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.

No : VERIFY the smart junction box (SJB) fuse 12 (7.5A) is OK. If OK, GO to A2.
A2 CHECK CIRCUIT CBP02 (GN) AND CPW30 (GY/YE) FOR AN OPEN
- Key in OFF position.
- Disconnect: SJB C2280E.
- Measure the resistance between LH front window control switch C535A-3, circuit CBP02 (GN), harness side and SJB C2280E-25, circuit CBP02 (GN), harness side; and between LH front window control switch C535B-3, circuit CPW30 (GY/YE), harness side and SJB C2280E-4, circuit CPW30 (GY/YE), harness side.

- Are the resistances less than 5 ohms for both measurements?
Yes : GO to PINPOINT TEST L to diagnose the delayed accessory relay circuit.

No : REPAIR the circuit. TEST the system for normal operation.
