I have the washer with the fiber optic light hookup that goes to the dash in the car. I got everything hooked up and still can't get it to pump. I took the cover off and it looks like the pump runs through it's cycle and stops but no fluid squirts. Do they make a rebuild kit for this and how do I remove the plunger from the plastic housing to replace the o-ring.

Less than 6 months ago I went to the GM dealer and bought a brand new washer pump.He told me that there were 3 available at GM warehouses across Canada so if your dealership can not find one down there, have him try the Canadian warehouses.
