Front windscreen washer

[pejohn]

I need assistance with a fault on my 2008 Jeep GC Limited 3.0L MB diesel motor (built by Daimler-Chrysler).
The front windscreen washer does not operate but the rear washer does.

My service manual indicates that the one windscreen washer pump operates for both the front and rear washer. The rotation direction of the pump motor directs the washer fluid to the front or rear. Power to the pump motor is toggled by the Front Control Module (FCM), part of the Integrated Power Module (IPM). This is initiated by the wiper switch on the steering column.

I have checked the fuses and relays without success. The wiring diagram shows the "Pump-Washer-Windshield" motor connected directly to the FCM through the IPM.

The windscreen wiper works normally.

Any help is much appreciated thanks.

Have someone try and wash the windsecreen whilst ur hands on the motor (in front of the left front wheel between the bumper and inner wheel guard) if you can feel it or hear it going then you may have a blocked pipe.
If not then you will know if it electrical. then you could test if there is power getting to the pump for the front wash. then its pump or wiring.

thats about all i got sorry, haven't heard of any common issues.

Good straight forward advice WH3.0
Other simple suggestion is to disconnect front pipe
Then activate washer & see if you make a puddle
