To check upward window operation, connect fused jumper wires:

Positive Lead	Measurement / Action	Negative Lead
C643-2	Courtesy of FORD MOTOR COMPANY	C643-1
C643-6	Courtesy of FORD MOTOR COMPANY	C643-7

Does the RH front window move up and/or down?

Yes

REMOVE the jumper wires. If the RH front window did not operate from the RH front window control switch, INSTALL a new RH window control switch. REFER to: Front Door Window Control Switch . If the RH front window did not operate from the master window control switch, INSTALL a new master window control switch. REFER to: Front Door Window Control Switch .

No	REMOVE the jumper wires. GO to E5

E5 CHECK THE POWER WINDOW CIRCUITS FOR AN OPEN

Ignition OFF.

Disconnect: RH Front Power Window Motor C608.

Measure:

Positive Lead	Measurement / Action	Negative Lead

C643-7	Courtesy of FORD MOTOR COMPANY	C608-1

Are the resistances less than 3 ohms?

Yes

MAKE SURE there are no mechanical binding conditions preventing the glass mechanism from operating correctly. If a mechanical binding issue is found, REPAIR as necessary. If no mechanical binding condition exists, INSTALL a new RH front window regulator motor. REFER to: Front Door Window Regulator Motor .

No	REPAIR the circuit in question.
