2003 Ford Escape -- rear window wiper not working turned on switch but nothing happens -- like no power going there. Also the running lights are flashing like in emergency mode . What do I look for to solve these problems. We do not have an owners manual to consult.? Would appreciate your help.

Did you check fuse's & relays ?
Rear Window Wiper Operation
The rear wiper motor is controlled by the SJB. The SJB supplies power to the rear wiper motor from the integrated rear wiper relay. The SJB will activate the relay when all of the following conditions are met:

• Ignition switch is in the ON position
• Liftgate glass and liftgate are closed
• Multi-function switch is in the ON or intermittent position

The SJB also supplies voltage to the rear wiper motor from SJB fuse 21 (15A) when the ignition switch is in the ON position. This power feed is used to continue the wipe cycle when the multi-function switch is turned to the OFF position. The SJB receives inputs from the multi-function switch that applies ground to the low speed wipe input or applies ground to the intermittent wipe input. When either of these circuits are grounded, the SJB activates the integrated rear wiper relay and power is supplied to the rear wiper motor to move the rear wiper motor from the park position. An internal switch in the rear wiper motor then moves to the run position which connects the accessory relay power to the rear wiper motor. When the rear wiper motor returns to the park position, the internal switch in the rear wiper motor moves back to the park position. If the multi-function switch is in the ON position, the rear wiper relay is still activated, power is supplied to the rear wiper motor, and the wipe cycle starts again. If the multi-function switch is in the intermittent position, the rear wiper relay does not activate until the predetermined dwell time has elapsed, at which time the SJB activates the rear wiper relay and the wipe cycle starts again. The SJB is the smart junction box .(computer )

Rear Washer System
The SJB supplies power to the rear washer pump from fuse 21 (15A) when the ignition switch is in the ON or ACC position. The rear washer pump receives ground from the multi-function switch when the wash function is turned ON. The multi-function switch also signals the SJB when the rear wash is activated and the SJB then activates the rear wiper.

Check fuse for rear wiper

Do you know how these wipers Work / what controls them ? Do you know what a smart junction box is ?

• Ignition switch is in the ON position
• Liftgate glass and liftgate are closed
• Multifunction switch is in the ON or INTERMITTENT position

The SJB also supplies voltage to the rear wiper motor from SJB fuse 21 (10A) when the ignition switch is in the ON position. This power feed is used to continue the wipe cycle when the multifunction switch is turned to the OFF position. The SJB receives inputs from the multifunction switch that applies ground to the low speed wipe input or applies ground to the intermittent wipe input. When either of these circuits are grounded, the SJB activates the integrated rear wiper relay and power is supplied to the rear wiper motor to move the rear wiper motor from the PARK position. An internal switch in the rear wiper motor then moves to the RUN position which connects the accessory relay power to the rear wiper motor. When the rear wiper motor returns to the PARK position, the internal switch in the rear wiper motor moves back to the PARK position. If the multifunction switch is in the ON position, the rear wiper relay is still activated, power is supplied to the rear wiper motor, and the wipe cycle starts again.

Do you know what DTC'S - diagnostic trouble codes are ?
Smart Junction Box (SJB) Diagnostic Trouble Code (DTC) Index DTC Description Source Action B1244 Wiper Rear Motor Run Relay Coil Circuit Failure SJB If the rear wiper is inoperative, Go To Pinpoint Test B . If the rear wiper is always ON, Go To Pinpoint Test D . B1245 Wiper Rear Motor Run Relay Coil Circuit Short to Battery SJB Go To Pinpoint Test B . B1614 Wiper Rear Mode Select Switch Circuit Failure SJB Go To Pinpoint Test D .
Did you have it checked for DTC'S ?

Probably the switch on your wiper stem.

Rather then swaping parts that don't fix it , testing the electrical is the proper way to diagnose . Using a wiring diagram to locate testing point's in the circuit . Tesing for B+ voltage at the switch , in an out , at the motor etc.... How to test power window switch motor 1985 2001 Toyota

sounds like you need another wiper motor

the motor is probably shot. if you can hear it run and nothing happens, you can eliminate a power issue. U r better off going to a junk yard(they will pull it for you) and replace it. Its pretty simple. Hope it helps

Nothing to do with your alternator my friend, you did nothing to cause this situation. Block the tires and put the emergency brake on, slide under to view the shift linkage on the trans, have someone shift ti for you, if the linkage does not move, you have a broken or disconnected shift cable that needs attention.

rear wipers are horrid for that... i just bent the wiper arm a little toward the window... works fine
