My $5.80 TMIC Sprayer

[Rosssub]

I've never once used my rear wiper or rear washer since buying the car, so I've removed the tail door interior panel and disconnected my rear wiper motor:

Now I can use my rear washer pump and rear washer switch on my wiper lever for my IC Spray button. Then disconnected the rear washer hose, and connected up a meter of 4mm vac hose. Tied beside the front windscreen washer hose up to the bonnet. (Passenger side pump is rear washer, hose goes straight into passenger guard. There's an OEM hose joiner near pump).

These bits are from the Mitre 10 Mega Gardening section, 98-99c each. I ended up using 3 elbows so a grand total of $5.80:

I drilled 4mm holes for the spray jets and 3mm holes through the scoops stiffeners for cable ties:

View from the bumper:

Can just see them poking out:

Eventually I'll get one of these 12v adjustable timer switches from Kemo Germany $45-55, Adjustable from 2 sec-23 min:

Then wire in a button on the dash with the timer set to about 5 seconds.

Great idea but wont you fail a WOF now the rear wiper and water sparyer isnt working isnt working?

[Rosssub]

Possibly but only a 2min fix. Change the hoses at the pump and reconnect rear motor.,

dont need that shit for a wof . v spec gtrs have it removed from factory

[Roo]

I\'ve never had a rear wiper for any of my wofs, never had an issue

I did this trick ages ago I should have written up back then

Our old Peugeot 405 never was never fitted with a rear wiper from factory.

As long as the wiper works you will be fine for the WoF

Did you get the timer all set up Ross? Gains?

[Rosssub]

I brought the timer, but it's on the shelf in the procrastination pile. Good things take time...

I use it most days and by the seat of the pants, it does work. Most noticeable on a hot day.

Next meet, you should take a look at Nick's setup. It's the same.

choice : too obvious & easy, surprised it hasnt been posted before : but ye if its there it has to work (generally) for a wof

not saying its dum, as you mentioned easy fix/not life not death deciscion

if you take off the rear wiper then it doesnt need to work Use bung to block hole where wiper once was. Old ladies BMW has no rear wiper
