Rear wiper not getting fluid

[vonD1025]

Anyone know how to fix the rear sprayer? Wiper works but no fluid. Also does anyone know how to adjust the front sprayer? It sprays high on the driver and low on the passenger.

This may sound like a dumb question but did you fill the rear wiper fluid tank? Can you hear the pump run?

 

[vonD1025]

Yes refilled the tank but no I can’t hear a pump. Is there one for the rear as well? 2 separate pumps?!?

 

[Dirtman]

Yes

Rear washer tank fills inside the rear hatch.

 

[vonD1025]

Where about?

Where about?

Right there between the spare mount and the light.

 

[vonD1025]

Awesome thanks. I’ll fill it and see if it works.

 

[vonD1025]

I filled that and still nothing. I don’t hear the pump. Where is the second pump located?

I'm guessing you have to remove the taillight to access it.

Remove the right-rear interior panel, and the washer fluid tank (with pump) will be right there at the back (IIRC, the pump is replaceable separately from the tank).

I don't believe the front nozzle unit is adjustable. If I had to guess, there probably is some debris in the orifices affecting their flow if it's not spraying right (also know: these old trucks are old-tech, the fluid normally just squirts out in two streams rather than a nice fan spray like newer vehicles have... They don't have real good coverage of the windshield even when working "correct").

Sweet thanks man. Yeah they spray streams but the passenger side barely hits it because of the angles they shoot. It sprays super high on the driver.

I tried using mine the last couple of days and nothing. I figured that it must be low on fluid.
Stopped and got some, thought that I should make sure the pump is running first and out comes fluid.
I guess the old fluid was freezing and now that it's warmed up a little the fluid thawed out.
Didn't have any problems with the front washers, maybe the engine kept the fluid just warm enough.

I think you can stick a sewing needle in them and adjust the nozzle direction.

Agreed. As I remember it, there's lot's of side to side adjustment, but not much vertical.
