Noticed today that when I turn on the rear wiper no water comes out. It was fine a few weeks ago. Since I was driving I could not troubleshoot much other than hold down the rear wiper switch for a minute or two to try and clear out any dirt. The water in the wiper reservoir is full. The front wipers work and front nozzles dispense the water thus the motor is fine (front and rear use same motor).
Once I parked the car I wiped the rear nozzle and also sprayed compressed air into the nozzle to try and clean it out. I tried again and heard water splash under the car. I saw that water was dripping from the rear driver side wheel well.
I looked over the factory service manual (REAR WIPER AND WASHER SYSTEM page 85 (http://www.nicoclub.com/FSM/Armada/2010/WW.pdf
) and see that the rear washer tube runs along the rear driver side wheel well.
Is it even possible to replace this tube if it is damaged?
I am going to see if the hose connected to the rear nozzle somehow came loose. Anyone done this? I will follow these steps:
1. Remove the plastic cover over rear hatch light to expose screws. Remove two screws. Then disconnect light cable.
2. Pry the plastic upper finisher (where the light was) off by pulling down. It will pop out.
3. Remove the rear cargo storage area top and lower liner to expose the frame.
Edit: Did some further investigation by taking a closer look at the wheel well. I could see water dripping and leaking all the way up the well. Opened the rear passenger (behind driver) door, lifted the seat and saw the carpet and floor liner was damp. I could see a bit of water as well.
I then removed the door trim and saw some electrical wires as well as a tube. Figured this is the tube for the spray.
I will need to remove all the floor liner to see if I can fix the tube myself!
