windshiled wiper and washer prob / sub79
 

hej there,


i have another construction site on my 79suburban.

the wiper tool
doesnt pump the water ...

i have tried something ... but the power of the pump
is to less ...

i have read the sites 8-29 ... in the light truck manual
but i couldnt find something for my problem.
(maybe i am to goofy)

look at the photos i uploaded ...

i know what all parts has to do ... and it runs.

but ... the power of the pump is not enough ...
the tubes are ok, water is in the tank ...
maybe the seals are "tired"???

what is the next I should do?
