I'm having a problem with the rear wiper fluid on my 07 H3. I push the button and I can hear the motor working, no lines disconnected, and no leaks. Thiking possible kinked line or clog somewhere or is it possible the motor is going out? The rear wipers work and everything works in the front the way it should. Anyone else have this problem? Thanks!!!

 

Switch the hoses from each motor to see if they are working. They are easy to get to. They are located on the passenger side top of the firewall. If both are working, then you just have to start looking for an obstruction. The rear washer hose can be accessed by removing the jack cover on the tailgate. Good Luck

 

Check fluid levels.. Had the same exact problem as you. Checked fluid and still had some in the resevoir, but the line to the rear will cut out when it gets low.

When I refilled mine it worked good as new.

 

Slightly off topic, but is it normal for the rear wiper to only go about 3/4 of the way across the back window? Any way to have it make a full 180 degree swipe?

 

Normal. Some have adjusted the home position to make it wipe more of a usable area.

 

That rear wiper is so small and useless that I have completely removed it from my H3, 3 years ago.

 

I have reclocked 4 H3 rear wipers so you get almost a full sweep. The other plus it the the rear defroster heats the wiper to remove ice from the edge of the wiper.

 

"I have reclocked 4 H3 rear wipers so you get almost a full sweep."

Tainter - how do you do this?

 

Loosen the wiper motor shaft nut like you were going to remove the arm and rotate the wiper further counterclockwise, then tighten the nut in the new position.

 

Mine stopped working. It had factory grease in the tube that had gone solid. Cleaned it out and all ok.
