Air wiper "motor valve" replacement
« on: July 21, 2018, 02:54:51 PM »
Passenger side was cracked/leaking..new valve from Rome Truck Parts...
Question: where's easiest access to this motor/valve? Outside from the front? Thought I could do it from under the dash but cant get to the top screws from inside, unless I tear the dash apart..?
Simpler to pull the whole motor to change the valve?, and again, from inside or outside?
Thanks

See the front 3 slanted panels. Take them off and they are right inside.

mine were leaking BAD would barely move the blades....to get new motors was over a grand so I opted to go with 24v electric conversion kit....best thing i ever did.   I used the air line that was for the wipers for my air seat....thats a win win

Rome Truck Parts has new motors for about 329.00 ea I think...surprised they were that high..thats getting close to the 900.00 I saw for electric conversion...Can I ask what you had to spend for your conversion dj?
Thanks

950.00 without the arms. Both 12v electric motors with the wiring already just plug in it together and run a ground and hookup 12volt wire to 12v stud in electric panel. I put in a 10 Amp fuse IIRC. Didn't get the electric water sprayer. It does come with the switches and knobs which replace the ones that are there. 2 speed and independent operation. The arms were 149.00 extra for the pangraph ones. I just used my originals. :)
