hi everyone.
im trying to fix my rear washer on my 03 h2.the wiper works fine however the rear washer doesnt work.the front washers work fine.im not sure if one motor runs them both.any suggestions.i tried blowing out the line thinking maybe it was clogged,but it wasnt.
thank you for any help.bill

 

Mine does the same thing. Tagging along.

 

mine does the same thing too. I checked the lines and the pump. Looks like one pump for front and back.

Did anyone fix this issue yet?

 

My 2006 H3 has two pumps front and rear neither of mine work fuses good

 

My 2006 H3 has two pumps front and rear neither of mine work fuses good fuse 9 and 16 when you pull the tank you can see both pumps

 

This could be a tricky one and I can only speak for a 2005 model year H2, but I believe they are the same.

The washer motor is reversable, it spins in one direction for the front washers and the other for the rear. It is controlled by an electronic pulse module housed inside the front windscreen wiper motor (not at the back where you would expect)

If your motor operates and your getting no pumped-water then that susggests a blockage somewhere.

If it doesn't then its probably the Pulse PCB at fault, usually caused by corrosion. It will require good desoldering/soldering skills to repair (my line of work) but hopefully it wont come to that. If it does I have diagrams and pictures to help, but is not for the faint hearted.

I have found this link on ebay which could be your best option, a new Wiper Motor Pluse Board it costs around $75 but double check the Part# (19120103) though it does say H2 2003. Also available on Amazon! ($70.78)

 

I pulled the tank and pulled the front windshield motor out ( rear on tank) , I flushed the tank and cleaned the motor and now front WS motor works . Put it back will wait until spring to repair rear. I guess I had VDC to that pump after all. Hard to function at 5 degrees lol

Will look at pulse module in the spring thanks for your input

 

Great news if you've fixed it!

 

well right under the windshield on the passenger side outside I switch the hose right there it took me 2 minutes now the front works and the back don’t
