Pinpoint Test E: A Single Power Window Is Inoperative - RH Front, Se, SEL
NOTE:
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.
- E1 CHECK THE RH FRONT POWER WINDOW OPERATION FROM LH FRONT CONTROL SWITCH
- Ignition ON.
- Attempt to operate the RH front window from the LH front window control switch.
- Does the RH front window operate when using the LH front window control switch?
- Yes : GO to E2.
- No : GO to E4.
- E2 CHECK CIRCUIT CPW14 (VT/WH) FOR VOLTAGE
- Disconnect: RH Front Window Control Switch C604.
- Ignition ON.
- Measure the voltage between RH window control switch C604-3, circuit CPW14 (VT/WH), harness side and ground.
- Is the voltage greater than 10 volts?
NOTE: Make sure the LH window control switch lockout switch is in the UNLOCK position.Fig 1: Measuring Voltage Between RH Window Control Switch C604-3, Circuit CPW14 (VT/WH), Harness Side And GroundCourtesy of FORD MOTOR CO.
- Yes : INSTALL a new RH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
- No : GO to E3.
- E3 CHECK THE LH FRONT WINDOW CONTROL SWITCH
- Ignition OFF.
- Disconnect: LH Front Window Control Switch C504.
- Carry out the LH front window control switch component test. Refer to COMPONENT TESTING Article for component testing.
- Did the LH front window control switch pass the component test?
- Yes : REPAIR open in circuit CPW14 (VT/WH). TEST the system for normal operation.
- No : INSTALL a new LH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
- E4 CHECK THE RH FRONT POWER WINDOW OPERATION FROM RH FRONT CONTROL SWITCH
- Ignition ON.
- Attempt to operate the RH front window from the RH front window control switch.
- Does the RH front window operate when using the RH front window control switch?
- Yes : GO to E5.
- No : GO to E6.
- E5 CHECK CIRCUITS CPW13 (BN/YE) AND CPW12 (GN/OG) FOR AN OPEN
- Measure the resistance between RH front window control switch C604-1, circuit CPW13 (BN/YE), harness side and LH front window control switch C504-11, circuit CPW13 (BN/YE), harness side.
- Measure the resistance between RH front window control switch C604-4, circuit CPW12 (GN/OG), harness side and LH front window control switch C504-10, circuit CPW12 (GN/OG), harness side.
- Are the resistances less than 5 ohms?
- Yes : INSTALL a new LH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
- No : REPAIR the circuit(s). TEST the system for normal operation.
- E6 CHECK THE HIGH CURRENT POWER TO THE RH WINDOW CONTROL SWITCH
- Ignition OFF.
- Disconnect: RH Front Window Control Switch C604.
- Ignition ON.
- Measure the voltage between RH front window control switch C604-5, circuit CBP47 (GN/BU), harness side and ground.
- Is the voltage greater than 10 volts?
- Yes : GO to E7.
- No
: VERIFY Smart Junction Box (SJB) circuit breaker 47 (30A) is OK. If OK, REPAIR the circuit. TEST the system for normal operation.
If not OK, REFER to the SYSTEM WIRING DIAGRAMS Article to identify the possible causes of the circuit short. REPAIR the circuit. TEST the system for normal operation.
- E7 CHECK THE GROUND TO THE RH WINDOW CONTROL SWITCH
- Ignition OFF.
- Measure the resistance between RH front window control switch C604-8, circuit GD145 (BK/BU), harness side and ground.
- Is the resistance less than 5 ohms?
- Yes : GO to E8.
- No : REPAIR the circuit. TEST the system for normal operation.
- E8 CHECK THE RH FRONT WINDOW CONTROL SWITCH
- Carry out the RH front window control switch component test. Refer to COMPONENT TESTING Article for component testing.
- Did the RH front window control switch pass the component test?
- Yes : GO to E9.
- No : INSTALL a new RH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
- E9 CHECK CIRCUITS CPW19 (VT) AND CPW20 (WH/OG) FOR AN OPEN
- Disconnect: RH Front Window Motor C608.
- Measure the resistance between RH front window control switch C604-7, circuit CPW19 (VT), harness side and RH front window motor C608-1, circuit CPW19 (VT), harness side.
- Measure the resistance between RH front window control switch C604-6, circuit CPW20 (WH/OG), harness side and RH front window motor C608-2, circuit CPW20 (WH/OG), harness side.
- Are both resistances less than 5 ohms?
- Yes : INSTALL a new RH front window motor. REFER to WINDOW REGULATOR MOTOR - FRONT DOOR . TEST the system for normal operation.
- No : REPAIR the circuit(s). TEST the system for normal operation.
