j_martell Posted March 14, 2017 Share Posted March 14, 2017 Pump? Does it run? Is the pick up plugged? Quote Lack of planning on your part does not constitute an emergency on my part....

Glensts Posted March 14, 2017 Share Posted March 14, 2017 The clicking is probably the relay, I have had to replace the motor pump assemblies before. Easy job on my 1997 Ch's so should be the same as yours. You could always put a test light on the wiring when you unhook from the motor and get someone to push the button. The pump is attached to the washer fluid reservoir.

Glensts Posted March 15, 2017 Share Posted March 15, 2017 on the 97's the relay and fuse panel is under the dash in front of the passenger seat. Not sure if the 2003's are still there or not Quote Link to comment https://www.bigmacktrucks.com/topic/49118-window-washer-not-working/#findComment-364572 Share on other sites More sharing options...
