Mazda 3 rear window washer

heffo500

Hi

Over the past 6 months the rear windscreen washer has stopped working.

I did some investigation yesterday and unfortunately the hoses appears to be blocked somewhere.

I partially removed the bumper and accessed the windscreen washer bottle and pumps, the rear pump is working fine.

I removed the hose on the other end and tried it to see was the nozzzle blocked and to no avail. I tried pumping water from the rear to the front and used a hand pump to try force water but no luck.


Am I no at the stage of replacing the complete hose? Is that a job a DIYer could do? Is anything I can pump in to break down the blockage?


Thanks

Really the best way to deal with blockage is by changing the entire hose.
There may be lots of little bits of crap in there, maybe even bits of the hose itself.

Thanks for the reply, Would it be a big job?

What year is your Mazda 3?
In theory it's easy, but in practise for a first-timer, I don't know..

Its 2006, I have done work on the car before suspension, wishbones, brakes and servicing etc.

I just wonder how much panels and such need to be removed due to the age of the car its probably not worth paying a mechanic to do.

Get a hold of Strimmer wire. It's a hard flexible plastic. It's cheap. Disconnect each jet from tube and push the wire through. If you can access the washer bottle all the better. You can disconnect from that end also and push any blockage through. Check inside the washer bottle sometimes bits of plastic & foil from the screen wash fall in and block the outlet. Replacing the lot is a pain in the hole. The wire will unblock it.

I put compressor air in and blew it out on a civic. It worked a treat

I tried this and it loosened a lot of dirt, I did this several times and drew washer fluid threw the pipe which pushed a lot more dirt out. There was also a load of dirt built up in a non return valve located between the hose and the nozzle which took a while to clean out.

Thanks all for the help.

Glad to hear this easier solution worked for you

Should have checked the fluid levels this time first as that was the problem.
