Hi All,

I searched old posts and didnt find anything about this. The last thing wrong with my car is the rear washer doesnt work which is a pain in the winter. I replaced the motor and still nothing. So I tried putting about 20psi of air in one end with the other end open. Nothing. I actually ran it up to 100psi and not a drop comes out the other end. It used to work but always had a kinda weak stream, then one day it just quit. I know the line goes under the driver side with the body harness, but from there I have no idea how it goes. I am guessing it goes to the rear then up one of the back pillars and down into the rear gate. Any suggestions as to where I should look? Or should I just run a whole new line? Both ends of the line hold 100psi. I wouldnt think a kink could hold that kind of pressure but I dont know where it could have been pinched either. Being so old I am surprised it didnt just break.

Thanks,
-William

 

poke poke... If nobody else has ever had this problem, does anyone know where the line goes? I have a full lift gate Bravada with two accordion tubes on each side of the top going into the body.

 

tube runs from the back of the res around the firewall, in a wire harness under the stereo and along the floorboard in a plastic tray under the driver's seat, under the d side rear passenger's seat down the d side center of the trunk area, into the d pillar at the far end and UP to the pillar, through a loom, into the hatch and over to the nozzle. good luck finding the blockage
BTW 99% of that is UNDER you auto carpet.

 

Yeah that is what I was afraid of. The only thing that I can think of is that I filled the back end up with just shy of 2000 pounds of drywall in contractor bags to take to the dump a few months ago. I am wondering if I might have crushed the loom under the carpet and flattened the damn tube. I pretty much only use the washer in the winter, but I remember it working in the fall and then not working when I went to use it a few weeks ago. The suspension took the weight. Maybe the 750 pound load rating is for the sake of this tube under the carpet... Does the tube go through the driver side D piller and driver side lift gate loom? Do I have to take off all of the trim to get the carpet up in the back or is there a trick to it?

 

to get to the carpet, pop off all of the trim and peel to your hearts content.

the tube lives in a plastic slip in between the ribs (sllight raised areas) on the trunk pan... it would take concentrated force on the tube to cause problems, not just weight in the back.

i believe the 750 load cap in the back is for the springs, not the tubing

as for which of the looms i dunno. d side makes the most sense since it has been running down the d side the whole way.

if you want to save some time you could try the air trick again with a stethoscope and trace the line listening for whistles ...
