i have a 98 voyager and the rear washer jet isnt working. i have tried changing the pumps over from front to rear and it works that way but putting the pipes back on the right pumps there isnt much action from the rear. the rear jet isnt blocked and the pump is pumping. dont know if there is a blockage in the piping and cannot take it out and check. do the pumps lose oomph to pump the water to the rear.
please help
